Fitting the HSV Triple Gauge Pod for the Chevrolet VE Lumina

  • HSV Triple Pod Gauges fitted to a VE Calais
    The following guide provides information on how to install the HSV triple gauge centre pod to a VE V8 Calais.
    Note: Most of the steps used in this guide will also be applicable to other models such as the Holden SS-V, Holden Berlina and Pontiac G8.
  • To remove the existing centre ventilation vent assembly, you will need to remove the following,
    The horizontal dash strips,
    The passenger side lower trim,
    The glove compartment,
    The drivers side lower trim,
    The Headlamp switch trim,

    To remove the horizontal dash trims, start from one end of the trim, pulling the trim outwards with an even amount of force.
    The horizontal trim pieces are held in place using a number of clips, which can be disengaged by pulling the trim piece outwards, away from the dash, as shown in the following image.
    Remove both trim pieces, which will allow you to access the upper glove box screws, as well as unclip the upper headlamp switch trim clips. (which will be covered later).

    Next, you will need to remove the lower drivers and passenger side trim pieces, located in the drivers and passengers foot wells.

    To remove the drivers side trim piece, you will first need to remove the two screws used to hold the OBDII connector in place.
    Next, to remove both these trim pieces, simply pull the trim piece downwards, starting from the back of the trim piece, disengaging the 3 clips holding the back of the trim pieces in place, and a further 3 clips used to hold the front of the trim piece in place.

    The following image shows the passenger side lower trim partially removed.
    This image shows the drivers side trim, partially removed.
    Unclip the foot well lamps from the trim piece by rotating the bulb holder anti clockwise.
    Next, unclip the electrical connector for the module located on the passenger side trim piece (If fitted).
    Finally, remove the trim pieces from the vehicle.

    The following Image shows the passenger side lower trim removed, as well as the clip locations.
    Removing the Glove Compartment
    Next, we will need to remove the glove compartment from the vehicle.
    NOTE: If you have factory navigation fitted, it will be nearly impossible to remove the glove compartment completely from the vehicle.
    It is recommended that if factory navigation is fitted, that you use a box, or stand to hold the glove compartment in place when all the mounting screws have been removed, so as not to place pressure on the Navigation module wiring harness.

    Firstly, remove the fascia surrounding the boot release switch, inside the glove compartment.
    Once the fascia is removed, you will need to remove the screw located beneath the fascia.
    Next, locate the second screw cover on the other side of the glove compartment.
    Remove this cover, and remove the screw located underneath this cover.
    Next, locate and remove the 2 screws located at the bottom of the glove compartment, used to hod the bottom of the assembly in place.
    These screws would have been hidden underneath the lower passenger foot well trim.

    Once you have these screws removed, you will need to remove the 4 upper glove compartment screws.
    The following image shows the location of these screws.
    Finally, with all the glove compartment mounting screws removed, the glove compartment assembly can be removed from the vehicle.

    Removing the Headlamp switch trim
    To remove the headlamp switch trim, Pulling from the top of the drivers side instrument panel trim that holds the headlamp switch assembly, carefully disengage the 2 clips on the outer side, and the two clips on the inner side of the trim, allowing the trim to be swung downwards slightly, and allowing access to the headlamp switch assembly.
    Disengage the headlamp switch assembly electrical connector by depressing the plastic tab on the connector (located on the right hand side of the plug), and pulling the plug away from the headlamp switch.
    Pulling from the bottom of the drivers side coloured instrument panel trim, disengage the remaining 4 clips holding the back part of the trim in place.

    Do not attempt to remove the trim yet !
    Next, carefully attempt to manoeuvre the trim plastic located nearest to the gear shift selector, downwards, trying not to scratch the steering column trim plastic.
    Take you time with this step, as the coloured trim panel does flex enough to allow you to do this, but it is fragile, and could easily break if you use too much force.

    Once you have the Inner most plastic coloured trim below the steering column plastic trim, attempt to manoeuvre the outer side of the trim around, and below the steering column plastic trim, again being carefully as to not scratch or damage the trim.
    Finally remove the trim from the vehicle.

    Removing the centre ventilation pod assembly
    To remove the centre ventilation pod assembly from the vehicle, you mist first remove the centre dash speaker grill.
    To do this, pull the grill upwards, towards the windscreen, starting from the back of the grill.
    There are four clips used to hold the grill in place, an disengaging these clips requires some force, although it is not impossible to do.
    With the centre speaker grill removed, locate and remove the two mounting screws located at the front of the centre ventilation assembly used to hold the assembly in place.
    Finally, remove the centre ventilation assembly by pulling the back of the assembly upwards towards the windscreen, disengaging the rear two clips holding the assembly in place.
    Next pull the assembly away from the dash, to disengage the two front clips use to hold the assembly in place.
    Finally, remove the assembly from the vehicle.

    Next, you will need to replace the dash centre ventilation ducting.
    To do this, simply remove the single screw, located in the picture below.
    Next, remove the Level 3 Dash Centre Ducting for the Calais from the vehicle by pulling the duct outwards, away from the dash.
    Finally, install the new Level 2 Dash Centre Ducting, as shown in the picture below.
  • The following step is probably the most fun, and easiest step.
    Firstly, the factory plug must be routed down the RHS of the radio stack, from the top of the Dash.
    The factory plug should have a plastic clip allowing the plug to be secured to the vehicle, using one of the available plug mounting holes locate behind the radio stack side trim pieces.
    Route the factor wiring neatly down the side of the radio stack, and mount the plug BEFORE finally fitting the HSV triple pod gauges.
    Once the factory wiring has been routed, simply clip the HSV triple gauge pod in place, and secure the pod using the 4 screws used to hold the previous pod in place.
  • With the above components removed from the vehicle, wiring for the HSV triple gauges should be relatively simple.
    In order for the HSV triple gauges to work you will need to make 6 wiring connections to the vehicle.
    These connections include,
    2 Connections to the Headlamp switch Connector (Ignition and Ground),
    3 Connections to the Steering Angle Sensor Connector (GM High Speed LAN Comms Enable, GM High Speed LAN Serial + and GM High Speed LAN Serial -)
    1 Connection to the Body Electronics Module (Interior Illumination)

    Firstly, you will require a suitable lengths of cable (around 2 meters) of different colours to help aid in identifying which cable goes where.
    The cable should be run from the left hand side of the Radio, (Where the HSV Pod Triple Gauge Connector has been mounted), through the back of the radio, up along the drivers side of the radio, and around to the light switch, Steering Angle Sensor, and Body Electronics Module.
    NOTE : For Left Hand Drive vehicles, the the steering angle sensor is located on the right hand side of the steering column, and the Light Switch, and Body Electronics Module is located on the Left Hand Side of the steering column.

    The following image details the connections that need to be made to the HSV triple gauge wiring harness.
    To connect to the HSV triple gauge wiring harness you could either cut the wiring connector off the harness, and splice the new wiring directly on to the wiring harness (Not Recommended), or you could source a male plug that is suitable for connecting to the harness as is.
    At present, I am unsure where such a plug can be sourced.
    For this example, I was lucky enough to have the Magnetic Ride Control Track Button, and its wiring harness included with the triple pod gauges that I had bought, and the switch wiring plug was an exact match for the factory triple gauges.

    Once you have a suitable plug, with around 2 meters of extended wiring, you can begin to route the wiring around the dash, and to the various modules that require connecting.

    Connecting to the Headlamp Switch Wiring Harness
    The first an most easiest connections can be made to the Headlamp Switch Wiring Harness for the Ignition Power and Ground.

    The above image will give you some idea of the wiring locations for the Headlamp Switch Wiring Plug.
    Locate the Pink Wire with Blue Stripe on the Headlamp switch wiring harness (Pin 10), and connect the Ignition Power line from the Triple Gauge Pod wiring Plug.
    Next locate the Black wire (Pin 4) from the headlamp switch wiring harness, and connect the Ground wire from the Triple Gauge Pod to this wire.

    Connecting to the Steering Angle Sensor Wiring Harness
    The Next connections to be made are the Data connections GM LAN +, GM LAN - and GM LAN Active (Power) which are connected to the Steering Wheel Angle Sensor Female inline connector.

    The above image will give you some idea of the wiring locations for the Inline Steering Angle Sensor Connector Wiring Plug.
    Locate the BROWN with BLACK STRIPE wire (Pin 3) on the Female Steering Angle switch wiring harness, and connect the GM FAST LAN + line from the Triple Gauge Pod wiring Plug.
    Next, locate the BROWN wire (Pin 1) on the Steering Angle switch wiring harness, and connect the GM FAST LAN - line from the Triple Gauge Pod wiring Plug.
    Finally, Locate the Blue wire (Pin 5) on the Steering Angle switch wiring harness, and connect the GM FAST LAN ACTIVE POWER line from the Triple Gauge Pod wiring Plug.

    With the Power and Data lines out of the way, the final step is to connect the back lighting control wire to the Triple Gauge Pod.

    Connecting to the Body Electronics Control Module X5 Wiring Connector
    The final connection to be made involves wiring in to the Body Electronics Module for the Tripe Gauges back light control.
    This wire connection determines when the gauges should be illuminated, as well as the illumination intensity when using the dimmer switch, or stealth mode.
    This connection is the most difficult connection to make, as gaining access to the body electronics module is a right pain.
    It is located on Right Drive Models just above the accelerator pedal.
    Locate the White wire with yellow stripe (Pin 24) from the fifth connector (Brown) on the Body Electronics Module wiring harness, and connect the Backlight Control wire from the Triple Gauge Pod to this wire.

    Once you have finished this connection you should be ready to test the Triple Pod Gauge Operation.
  • To test the Triple Gauge Pod wiring simply switch the Ignition Switch to the On Position.
    The First time the Gauges are powered up, they will attempt to automatically zero themselves.
    One completed, without the engine running you should see the Battery voltage reading show something around 12V to 14V depending on your battery condition.
    The Oil Pressure and Oil Temperature Gauges should be sitting on the Zero marker.
    If this is not the case, them you may need to adjust the zero position on the gauges needle.

    Finally, start the engine.
    If you have a post MY08.5 Build car, then both the Oil Pressure and the Oil Temperature gauges should display a reading.
    If you have a Pre MY08.5 Build car, the Oil Temperature Gauge will not function.
    This is normal, and to rectify this problem you will need to have the Oil Temperature reading enabled on your vehicle.
    This can be achieved either with a Tech2 tool, or by using tuning software such as EFI Live, which will allow you to enable the Oil Pressure reading to be broadcast on the GM LAN bus, and be available to the Oil Pressure Gauge.

    Finally, switch the park lamps to the On Position.
    The Gauges should illuminate with the park lamps in the On Position, and the ignition switch turned On.
    If the Park lamps are turned off, or the ignition switch is turned off, then the triple gauge illumination will also turn off.
