Rb20det Ecu Wiring Pinout

[Min_R32]

Hey guys, i need to find these four connections on my ECU. Ive never touched the wiring on my ECU before and just wanted to make sure that i have the right wires.

I need:

+12V Ignition Switched pin

Ground Chassis 0V

Oxygen Sensor signal

Airflow Meter signal

Now ive found this ecu diagram pinout

Now im pretty sure that for the 12v ignition switched im looking at pin 45, and for Ground 0V im looking at pin 10 or pin 20. (Please correct me if im wrong)

Im not sure where the other two pins are, could anyone help I know how to check these with a multimeter but i just wanna make sure first =)

Ok i think i just found the airflow meter signal, on pin 27. It says rear is that the oxygen sensor?? or the AFM???

=/ i found another diagram which says the exhaust gas sensor is pin 55 which on the diagram above says nothing.... The voltage on the oxygen sensor usually fluctuates when the throttle is blipped so i think i can test for that one. But if anyone could just double check for me! it would be appreciated.

Pin 29 will be the O2 sensor signal.

+12V Ignition - Pin # 59.

Ground Chassis 0V - Pin #50,60.

Oxygen Sensor signal - Pin # 29

Airflow Meter signal - Pin # 27

I'm guessing you need to wire in a SAF-C and possibly an Apexi TT? If so you may also need:

Throttle signal - Pin # 38

Knocking signal 1 - Pin #23

Knocking signal 2 - Pin #24

RPM - Pin # 7

Good luck
