On what car?

1G's are easy, three wires.
DLC pin 1 to ECU pin 1.
DLC pin 10 to ECU pin 2.
DLC pin 12 to ground.

IF YOU CAN FIGURE THIS OUT FOR ME STEVE I WILL TRULY CONSIDER YOU A WISEMAN. shit sorry about the caps. i just remembered that the diagnostic port came off a 91 and the main harness is from a 93. i dont think there should be a difference should there? thanks in advance.

Pin 1 on the DLC has a Yellow wire.
Pin 10 on the DLC has a White wire.
Pin 12 on the DLC has a Black wire.

The rest are for different functions other than datalogging.
