Rb25 - R32 Swap Question

[Zimm]

I got the rb25det series 2 swapped into my r32
I am running nistune and Running Rb20 engine harness and coils

I am having problems with my gauge cluster,
The tach wont work (did before)
and the fuel and oil pressure gauge when I start the car max out
the speedo works and when I hook my comp up to the ecu it shows the rpms there

So im guessing somewire maybe crossed or no ground im not sure but I checked all the engine harness wires and there all good

anyone got an idea on why this is happeing

Or maybe if anyone knows how to get just the tach to work that would be awesome, if not I will have to buy after market tach which I didn't really wanan do

Sounds like a few wiring problems under dash.

RPM signal goes from CAS to ECU and then to dash. If seeing rpm at ECU, then it's a problem with the wiring from ECU to dash. The manual has a wiring diagram in the back that should show wiring and where it goes from ECU to dash. Next to each line is say YB or similar to say Yellow Black wire, so know which wire is which from ECU plug.

Wiring diagram looks like this (for R33 and you need the R32 version) -

the #7 pinout doesn't have no signal when running it did show .07volts when ignition was on I believe
