Which pin connects ECU and ATTESSA?

[blind_elk]

Just fitted a RB25DET VVT engine (ex Stagea) into my R32 GTS4, and replaced the ECU with a wire-in Wolf 3D 4+. Now the "4WD" light is on.

I understand the factory ECU has a connection to the ATTESSA ECU (presumably to tell ATTESSA that engine is running). Does anyone know:

1 which wire?

2 How to I connect it to fool ATTESSA

TIA

anyone?

I think its pin 56, can someone confirm, and tell me the colour code of the wire.

OK, solved the second question. Just need confirmation on the colour coding of the wire.

Come on, someone out there has a R32 GTS4 that they can go out and have a look at the ECU connector.

Please?
