88 GP SE A18 ECM Pin Out ?!?!?

I posted this on 60 degree v6, but I thought I'd try here too in case.

 

I'm in the process of doing a turbo swap onto my 88 GP with a HM 282. I have all the mechanical done, but I'm having trouble with the ECM Pin outs. I have a FSM for my car, and it doesn't list a wire being at A18, where I want to put the wastegate solenoid wire, but sure enough there is. I've looked all through my manual and I cannot find what the hell A18 is in my car. I found one reference in the back that has all engine connectors, and it shows a black w/pink tracer being located there, but doesn't describe it in any way. Does anyone have any idea what this could be?

 

Thanks,

Jon

Yeah, I found it, it was for the air pump. I was just looking at the whole engine wiring harnese in the FSM. It has pin outs for everything minus that 1 wire. The manual actually lists the wires from A1-A22 but it skips A18. It's like they deleted that line.
