Hi SSV364
I'm currently using early (E1 I think) Gauges with an E3 module.
You can mix and match the gauges and modules, however there are a couple of things to keep in mind.
1) The module tells the gauges what position to be in (Eg 50% deflection). The module does not actually send the
raw data to the gauge for interpretation. (Eg it does not send 15V, it tells the volts gauge to move the needle to 50% or the halfway point)
2) With the White gauges, there are two types (The only difference is the faces).
Narrow readings (E1, where the max voltage reading is 16V)
And
Wide readings (??? E2 I think ???, where the mac voltage reading is 18V)
E3 models use Wide readings.
Soooo, what this actually means is if you are using narrow reading gauges from an E1 model,
and these are connected to a wide reading module, then the needles will be pointing in the wrong positions. (Much lower than what the actual values are)
(Eg I have narrow E1 gauges, and an E3 module, and the needle NEVER goes above 12V (When in actual fact the voltage is around 15V)
Likewise, if you went the other way, and fitted an E1 module (Narrow Readings) to E3 gauges, then the needles will be positioned much higher than the actual values.
Looking at your gauges, you have Wide reading gauges, so you will be fine if you use an E3 module.
Having said this, the electronics in the gauges are all the same, its just the faces that are different.
You can get Narrow, or Wide reading white faces for the HSV gauges on eBay, which is what I have done to correct my problem.
I hope this information helps ?
