R32 GTS-4 with RB25DET 4wd fault

[dieseldog]

I have an R32 GTS-4 with a Stagea RB25DET and it has a 4wd fault. Looking at the flash code on attesa ecu it's missing the TPS signal. Would anyone know which pin on the RB25DET engine ecu is the TPS out put signal that need to run to the attesa ECU and which pin on the ECU is the input from engine. Any advice would be appreciated or if I'm on the right track fixing this fault.

The wiring diagrams are in the workshop manuals, or you can google the diagrams up.

And no, I don't have them with me.
