Upgrading Instrument Clusters for the Ford EF II Falcon

Introduction


  • This Document Describes the differences between various models of Instrument Clusters fitted to the EF/EL/NF/NL/DF/DL Series Falcons.
    It also has information on Upgrading an Instrument Cluster, modifications that need to be made, wiring information, swapping odometer readings, and some points to watch out for when performing these upgrades.

    With the EF series of Falcons (and Derivatives), there were four models of Instrument Clusters that were fitted to these vehicles.
    Theses Clusters Featured white Needles, with White Illumination, LCD based Odometers, Seat Belt Warning, and a Unique Diagnostic Mode
    With the Advent of the EL, all these clusters were revised to give a cleaner look, with Orange Needles, Less "Tick Lines" on the Speedo and Tacho, and a new Fuel Door Release Indicator.
    A new Cluster was also added to the range, which was fitted to the XR (Tickford) series of Vehicles.
    This new cluster is exactly the same as the Fairmont Mid Series Cluster, with the exception of a Tickford Logo being placed on the Tacho Section.
    The Following Images of Clusters have been taken from various EF/NF/DF Models, and include,
  • NF Fairlane Instrument Cluster (High Series) as fitted to Fairlane, and LTD Models
  • EF Chaser (Police) (Mid Series Special) Instrument Cluster, as fitted to ex Police Pursuit Models
  • EF Sports Cluster (Mid Series) Instrument Cluster, as fitted to Fairmont, Fairmont Ghia, XR6, XR8 models
  • EF Standard Cluster (Low Series) Instrument Cluster, as fitted to Gli, and Futura Models

    NOTE : If fitting Fairmont/Fairmont Ghia Instrument Cluster to a GLi/Futura/XR Model, it will be necessary to add a Resistor to the Instrument Cluster Circuit Board, in order for the LCD Backlighting to function correctly.
    Please see below for further information regarding this
    A Big thankyou goes out to WAYNE for Discovering this Interesting Quirk with the EL Clusters, and for working out how to fix this problem !

    The EF Chaser (Police) Series Cluster is a special issue cluster, and was made only available to Police issue EF Falcons.
    These Falcons had a number of upgrades made to the vehicle, with the Instrument Cluster being one of them.
    The Chaser (police) Cluster is based on the Mid Series Instrument Cluster, but with 2 very important modifications made to it.
  • Instead of a Diagnostic Mode that is available with all other EF series Clusters, the EF Police Cluster has a Speedo Calibration Feature, which allows the user to calibrate the Speedo, and Odometer Readings with a percentage error.
    These Clusters are very rare, and a re a much sought after item because of this calibration feature, as it makes wheel, tyre, and Diff Changes very easy in regards to calibrating the Speedo.
    The Calibration range can be made between +-10%, with 0.5% increments.

Upgrading and swapping Instrument Clusters


  • With exception to the High Series cluster, and fitting Fairmont Clusters to GLi/Futura/XR models, it is possible to change between different Cluster models rather painlessly.
    The Low, Mid and Police Clusters all use the same connectors, same Bulb holders, same needles, and very similar circuit boards / Needle Assemblies.
    NOTE : Fairmont, Fairmont Ghia, and EL-GT Clusters are missing 1 Resistor, that is used to allow LCD Illumination, with the Park Lamps on !

    When fitting an EF/EL Fairmont, EF/EL Fairmont Ghia, or EL GT Instrument Cluster to an EF/EL GLi/Futura/XR model Falcon, you will Need to add this resistor for the LCD Panels to function correctly.
    Without this resistor, the LCD Panels (Clock/Trip Computer/Odometer/Climate Control) WILL NOT ILLUMINATE AT ALL WHEN THE PARK LAMPS OR HEADLAMPS HAVE BEEN TURNED ON !)
    NOTE : This resistor is not required when Fitting Fairmont/Fairmont Ghia/EL-GT/Fairlane/LTD Clusters to vehicles fitted with a High Series BEM (Fairmont/Ghia/EL-GT/Fairlane/LTD)
    Information for fitting this resistor (and the reasons behind it - are outlined below.

    Some important steps to watch out for when doing an Instrument Cluster conversion will include,
  • 1. As stated above, when fitting a Fairmont/Ghia, or GT Cluster to a GLi/Futura/XR Model, you will need to add 1 Resistor to the Cluster Circuit Board - This procedure is outlined below
  • 2. The Odometer Reading will need to be changed. (Remember your Pink slip will have this reading on it from your previous years Registration - There is a $10,000 fine for Fraudulently Winding Back your Odometer Reading.)
  • 3. If Upgrading from a Base Instrument Cluster, The Oil Pressure Switch will need to be replaced with an Oil Pressure sensor.
  • 4. If adding the Low Coolant Warning Lamp on Gli Vehicles, an extra wire, and a Coolant Sensor switch will need to be added. (Note All Clusters have the ability to display the Low Coolant Output).
  • 5. If adding the Low Windscreen Washer Level Warning Lamp, a new Washer Bottle, with Level sensor, and an extra line will need to be added for the Warning to work. (Note All Clusters have the ability to display the Low Windscreen washer Level LCD Warning).

    Some Common misconceptions with the EF and EL series Clusters include
  • 1. There is no difference with V8 and I6 Tacho sections ! - Don?t ask me why, but I definitely have a V8 Fairlane Cluster fitted to my EF, and it has an Inline 6 motor. The Tacho section on both the original, and Fairlane Clusters are within 20RPM tolerance of each other, throughout the entire rev range !
  • 2. The Odometer Readings can be swapped, changed or kept. The Odometer Reading is held within the Instrument Cluster, not within the EEC-V Engine Management, nor does the Instrument Cluster have a Backup Memory, or a Tamper-proof mechanism to deter Odometer Fraud !
  • 3. There is no Electrical, or Calibration Difference within the Speedo sections of the cluster, in terms of different Factory fitted Diffs, wheel, and Tyre Ratios. Changing Clusters will not alter the Factory Speedo readings.

Adding the LCD Dimming Resistor


  • A Big thankyou goes out to WAYNE for Discovering this Interesting Quirk with the Fairmont Clusters, and for working out how to fix this problem !
    NOTE : When fitting a Fairmont/Fairmont Ghia/EL-GT Instrument Cluster to a GLi/Futura/XR Model, you will need to add 1 Resistor to the Instrument Cluster, in order for the LCD Panels to Illuminate correctly.
    Without this resistor, the LCD Panel(s) (Clock/Trip Computer/Climate Control/Odometer) will not Illuminate when the Park Lamps, or Headlamps have been switched on.
    The reason for fitting this resistor is Fairmont/Fairmont Ghia/EL-GT/Fairlane/LTD Model Falcons use the Body Electronics Module to Dim the LCD Panels, when the Headlamps are switched On.
    The Low and Mid Series Body Electronics Modules DO NOT HAVE THIS FACILITY.
    Fords Method of getting around this problem, was to fit a Resistor the Instrument Clusters for use in GLi/Futura/XR Models.
    This Resistor Feeds the Negative LCD Dimming Circuit, when the Park Lamps are on, and without it, the LCD Illumination Bulbs will not Illuminate.

    Please Note : Fitting this resistor does not apply when fitting an XR Cluster, to a GLi/Futura/XR Model Falcon.

    Finally, it is also worth noting that if fitting a GLi/Futura/XR clusters to a Fairmont/Fairmont Ghia/EL-GT, THIS RESISTOR WILL NEED TO BE REMOVED, and IN ORDER FOR THE Variable Dimming Function to work correctly with the LCD Panels.

    The location of this resistor is on the Instrument Circuit Board, and is located to the right of the RHS Instrument Cluster Connector.
    I.E. You will need to remove the Dials, and the circuit Board, flip the circuit board over, and solder the resistor in the position shown below.
    The Following Picture will give you a better idea of its location,
    The Location of the Required Resistor for LCD Dimming

    The Resistor you will require is a 1Watt, 47 Ohm Resistor.
    The Colour Bands for this resistor are Yellow, Violet, Black, Gold (5% Tolerance, 4 Band type).
    Or for a 5 Band 1% Tolerance type resistor , the colour bands would be Yellow, Violet, Black, Black, Brown.
    Please note though, you will Require a 1Watt type Resistor, due to the currents required by the LCD Panels.
    The following are Catalogue Numbers for the above resistors, from various Electronics stores.
    Jaycar - Cat RR-2542 - 47R 1 Watt Carbon Film, 5% ($0.32 Pkt of 2)

    Adding the Resistor
    To do this, you will obviously need to remove the Instrument Cluster, and Disassemble.

    To Disassemble the Instrument Cluster,
  • 1. Remove the Clear Lens, and Black Plastic Lens Holder by removing the 2 Torx Screws Located at the top of the instrument cluster. (NOTE : You do not require a Torx bit to do this, a flat-headed screwdriver is perfectly adequate.)
  • 2. Unclip the Black Plastic Lens Holder by unclipping the 2 clips at the top, and 3 clips at the bottom of the cluster.
  • 3. Remove the Plastic Masking Lens away from the Dial Faces
  • 4. Remove the 2 Torx Screws, Located at the back of the Instrument Cluster (Near the Bulb Holders). These screws are used to hold the Dial Faces in place.
  • 5. Once these screws have been removed, gently ply the Dial faces away from their respective metal clips. This requires some force to do this, but it is important that you pull the faces directly up and away from the circuit board ! Do not try and Wiggle the faces away from the board.
  • 6. To remove the Cluster Circuit Board, Remove the 2 Torx screws located At the bottom of the Circuit Board.
  • 7. Finally, lift the circuit board from the top, up, and out of the Cluster casing. (Pulling the bottom electrical connectors out from the Casing housing).


    Once the location is found, Heat up the Solder points outlined above, with a soldering iron, and attempt to clean the area of the solder.
    Below the solder are mounting holes for the resistor. Removing the Excess Solder will allow the resistor to be mounted by placing its legs through these holes.
    Once fitted, solder in place, and re-assemble the Instrument Cluster, and test.

Swapping Odometer Readings


  • Obviously, when swapping Instrument clusters, you will want to keep the same Odometer Readings for your vehicle.
    Because the EF and EL series vehicles have a digital Odometer, simply cracking open, and winding the Odometer backwards will not work.
    So how is the Odometer reading changed ?
    Firstly, you will need to know a little bit about electronics.
    The Odometer Reading, as well as the Trip meter, Service spanner setting, and possibly other settings, are stored in a device known in the Electronics industry as an EEPROM, or E2PROM, (pronounced E squared Prom).
    An E2PROM is an Electrically Erasable, Electrically Programable, Read Only Memory, very similar to the Flash upgradeable Computer Bios.
    Anyway, without boring you on how an E2PROM works, the model used in the VDO Instrument Clusters is an X24C44 Surface Mount model.
    This chip is located approximately 1cm to the right of the chunkiest chip, on the back of the Instrument Cluster Circuit Board.
    This is the same position as per the Low, Mid, and High Series Instrument Clusters.
    The Location of the EEPROM, on the Mid series Instrument Cluster

    As was previously mentioned, this chip is surface mounted, that is you will need special tools in order to remove it.
    It is this chip that stores the Odometer, as well as other readings.
    When swapping Instrument Clusters, you will need to De-Solder this chip, and swap it from your Original Instrument Cluster, to your new Instrument Cluster.
    WARNING : I take no responsibility for any Damage that may be caused through any actions that are taken, that are directly, or Indirectly related to the information provided herein !
    This is a small, delicate, and heat sensitive chip, and as such, is very susceptible to permanent damage, which WILL if damaged, render the instrument cluster USELESS !
    Under no circumstances will Matthew I Jones be held responsible for any such damage.
    Remember, this site is provided to you, free of charge, and it is up to yourself to correctly determine what modifications can be safely conducted by yourself !

Adding an Oil Pressure Sensor


  • Because the Low series Instrument Clusters do not have an Oil Pressure Meter, these vehicles do not have an Oil Pressure sensor fitted.
    Instead of the Oil Pressure sender, they use an Oil Pressure switch.
    What is the difference between these Oil Switch sender thingies I hear you ask ?

    The Oil Pressure switch is just that, it switches to Ground when the Oil Pressure drops below a certain level.
    This means that the Oil Pressure switch is only good for Switching a low Oil Pressure Lamp On or Off.
    If a Mid or High series Instrument cluster is used with an Oil Pressure switch, the Oil Pressure gauge will either show 0 Oil Pressure, or very very High Oil Pressure, with no intermediate pressure.

    The Oil Pressure Sender has a constantly variable Voltage, that is directly related to the Oil Pressure.
    Obviously, this variable voltage is required for an Oil Pressure gauge.
    The Mid and High Series Instrument Clusters also compare this voltage, and if the Voltage falls below a predetermined level, the low Oil Pressure Warning lamp is Illuminated.

    The Oil Pressure Switch, and Oil Pressure sensor are located in exactly the same place, and as stated above, if fitting a Mid or High series Cluster, (I.E. upgrading from a Low series cluster), the Oil Pressure switch will need to be replaced with an Oil Pressure sensor.
    These sensors are located roughly about 2 inches above the Oil Filter, on the Inline 6 motors.
    The sensor also has a single wire coming from it, with a spade electrical connector.
    The Oil Pressure sensor can be purchased from Wreckers for around $20.
    Or alternatively, can be bought from Ford for around $50.00 - Ford Part Number EF-9D290-A

Adding the Low Coolant sensor


  • This is a worthwhile modification that can be made to the EF and EL Series model Falcons, as it can be added to ALL Instrument clusters, (low, Mid, and High Series).
    Considering the number of cases of Head Gasket Problems with the EF and EL, this modification could save you a lot of money !
    The only models that do not have the low Coolant Sensor are Unfortunately, the GLi models.
    The Low Coolant Sensor is fitted to the Plastic coolant Bottle, and as such, you will need to purchase a coolant overflow bottle with the sensor hole fitted.
    The low coolant sensor part you will require is 10K888-AA, and will set you back around $80.00.
    The Low Coolant Sensor available from Ford
    If required, the Coolant overflow bottle can be bought from eBay from around $50.00
    You will also require the plug fitting if purchasing a new coolant overflow bottle, which can be obtained from a wrecker, or Ford.
    Fitting the low coolant sensor to the coolant overflow bottle
    Once this part has been fitted, you will then need to wire it up to the Instrument cluster
    One wire is Black, and is connected directly to ground.
    The other wire colour, Yellow/Red, should be connected directly to the Instrument Cluster, low coolant lamp, On the Right Hand Side connector, Pin Number 3.
    Finally, you will need to add the Low coolant sensor Bulb to the Instrument Cluster.
    This Bulb is located right next to the LCD Panel, on the Right Hand Side (With the Back of the Instrument Cluster facing towards you).
    The socket for this bulb may be blanked out by a round paper sticker, simply remove this sticker, and fit a new Bulb and Bulb Holder.

Adding the Fog/Spot/Driving Lamp Warning Circuit


  • A Big thankyou goes out to WAYNE for Discovering this Interesting Quirk with the EL Clusters, and for working out how to fix this problem !
    The EF and EL series Instrument Clusters have the facility for a Fog/Spot/Driving Lamp Warning lamp, just above the Smartlock Warning Jewel, on the Instrument Cluster.
    Although the Facility is there, there are some additions that you will need to make to the Instrument Cluster, in order for this function to work.
    Firstly, a wire must be run to Pin 8, of the Left Hand Side (Passenger Side) Instrument Cluster.
    This wire Needs to have +12Volts running to it, in order for the Spot Lamp Warning Jewel to Illuminate.
    With most aftermarket Spot/Fog/Driving Lamp Circuits being triggered by switching +12V to the Spot Lamp circuit, this should not be a difficult task.
    Once this has been completed, you will need to add an extra Bulb, and Bulb Holder to the Instrument Cluster.

    There is a blanked out socket, just above the Smartlock LED. This socket is blanked out using a round paper sticker, and can easily be removed by simply peeling it off the circuit board.
    Once this sticker is removed, you will need to fit a Bulb Holder, complete with a Bulb to this empty socket.
    It is recommended that a 1.2Watt Globe is fitted to the Bulb Holder, though this is not terribly important (An increased Bulb Wattage will do no damage to the Cluster), you may find that at night time, 2Watt Bulbs may be too bright, and annoying.
    If you have an EF Model Instrument Cluster, then this is all that is required. And you are now ready to test the Spot/Fog/Driving Lamp warning jewels operation.

    Unfortunately, EL Model Instrument Clusters are a slightly different matter.
    These clusters are missing 1 Diode that is VITALLY important for the Spot Lamp Warning Jewel operation.
    For this circuit to function correctly, you will need to add 1 x 1N4004 Signal Diode to the circuit board, roughly behind the Battery Voltage Gauge. See the picture below for more details.
    To do this, you will obviously need to remove the Instrument Cluster, and Disassemble.

    Please see the next chapter for detailed information on disassembling the instrument cluster.

    Once this has been completed, you will need to locate the position that the 1N4004 Diode will need to be soldered in place.
    The following image will assist you in this process.
    The Location of the Diode, for the EL Fog Lamp Warning Circuit

    Once the location is found, Heat up the Solder points with a soldering iron, and attempt to clean the area of the solder.
    Below the solder are mounting holes for the Diode. Removing the Excess Solder will allow the Diode to be mounted by placing its legs through these holes.
    The Diode ! MUST ! sit in the direction where the Silver Band (the Cathode end) is towards the center of the circuit board.
    This is VITALLY IMPORTANT, as fitting the diode in the wrong direction will mean that the circuit will not Function AT ALL.
    Once fitted, solder in place, and re-assemble the Instrument Cluster, and test.

Disassembling Instrument Clusters


  • To Disassemble the Instrument Cluster,
  • 1.Remove the Clear Lens, and Black Plastic Lens Holder by removing the 2 Torx Screws Located at the top of the instrument cluster. (NOTE : You do not require a Torx bit to do this, a flat-headed screwdriver is perfectly adequate.)
  • 2.Unclip the Black Plastic Lens Holder by unclipping the 2 clips at the top, and 3 clips at the bottom of the cluster.
  • 3.Remove the Plastic Masking Lens away from the Dial Faces
  • 4.Remove the 2 Torx Screws, Located at the back of the Instrument Cluster (Near the Bulb Holders). These screws are used to hold the Dial Faces in place.
  • 5.Once these screws have been removed, gently ply the Dial faces away from their respective metal clips. This requires some force to do this, but it is important that you pull the faces directly up and away from the circuit board ! Do not try and Wiggle the faces away from the board.
  • 6.To remove the Cluster Circuit Board, Remove the 2 Torx screws located At the bottom of the Circuit Board.
  • 7.Finally, lift the circuit board from the top, up, and out of the Cluster casing. (Pulling the bottom electrical connectors out from the Casing housing).

Adding the Low Windscreen Washer Sensor


  • The Low Windscreen Washer Fluid Sensor detects when the level of the Windscreen washer fluid falls to a level that allows only a few more seconds of Windscreen washer operation.
    The Warning lamp is integrated within the LCD Odometer panel, on the EF and EL Series Falcons, and surprisingly enough, it is actually available on all clusters.
    Unfortunately, if you have a GLi Model, without ABS, then you will not have the electrical connector, and wiring already available.
    EF/EL Futura Models, and GLi Models with ABS fitted will have this connector already fitted, and wired up, so all that is needed is to add the Low Washer Fluid Switch, which is part of the Windscreen washer Bottle.
    The Windscreen washer Level sensor is a simple On Off switch, and is integrated within the Washer Bottle, using a rubber grommet.
    The sensor can be removed and fitted, but you would probably find that it is easier to simply purchase a new/used Bottle with the sensor already fitted, from a Fairmont, Fairlane or LTD.
    The electrical connector is a Female T piece, and is exactly the same type as used on the Front Turn signals.
    This piece has 2 wires coming from it, 1 wire is connected directly to ground (Black), and the other wire goes to the Instrument Cluster Right hand side connector. (Pink/Yellow wire)
    (See below for Wiring Information, in regards to the Right Hand Side Instrument Cluster Connector).
    As mentioned above, when the Windscreen washer level drops to a low level, this switch conducts, causing the Pink/Yellow wire going to the Cluster to be grounded.
    The Instrument Cluster will then Illuminate the Warning segment, on the LCD Panel.
