Replacing R32 Gtr Oem Gauges

[Scooby]

Guys;

this follows on from a thread on gauge accuracy in an R32 GTR. I understood from a gauge repair place that sometimes if you remove standard gauges (I'm looking at building a custom dash as I don't want to have gauges all over the place) it has undesirable side effects ie I've read a recent thread saying that removal of the oil temp gauge has made the oil press light illuminate but I haven't witnessed this myself.

Can anyone definitively state what is required when replacing the standard gauges in terms of wiring etc? Not concenred about power or sensor connections, but anything that might not be immediately obvious such as a connection between computer and gauge that needs to be maintained etc. In other words are there any traps?

Thanks

Hi - having this issue at the moment.

Unplugged the 3 factory 3 din gauges, and the oil light in the dash stays on - upon further investigation, that light shows both warnings for oil press AND oil temp. So, it would appear that when the ECU sees 0V across the oil temp gauge, it throws on the oil light.

So, my thinking is, seeing that I've replaced the 3 gauges with Defi 52mm oil temp, press and water temp gauges with warning, all I need to do is to unplug the lead going to the oil light...

Looking at the (horrible) dash wiring diagram, it seems that if I pull wire 34 going into the dash, this will kill the oil light.

I don't have the car at the moment (will be a few weeks at the shop) so will try it when I get the car back.

Note, justinfox replaced his with the Defi din gauges, and didn't have a problem. Maybe these gauges plug into the factory loom, so no issues?? I can't remember who it was who installed them for him, but maybe a quick call to whoever did it would help too

Hope that helps
