Searched and found the schematic. Plug pulled from 2000 Firebird. Need to connect to 96 Firebird LT1 PCM.

Problem: Diagrams I found match plug perfectly. 2-purple=serial data
4-black= ground
5-black/white= ground
16-orange=12v batt.

I can only find these wires and I have them tagged:
Tan=serial data signal wire
white/black = diagnostic request signal
purple = output field service


I have the 12 volt wire correct and ran the 2 grounds to the neg batt post. Purple wire with pin 2 and no codes, scanner error. Also tried the tan with pin 2 same thing.

this could be pin 2 or pin 9

not sure

This should be pin 6

You need to find a pinout for the 96 camaro DLC

Anyone have that pinout schematic?

Oh, read directions first! Plug in scanner and turn key to on position, yep I'm an iiiidioooot! Key in the on position code PO123 throttle position sensor A circuit high input. Definitely the cause of the high idle and probably everything else.

Yea, all OBDII from what I have seen is just 2, 4, 5, 16.
I know that the OBDI uses 9, and a couple of other ones, some of them went to the Auto Transmission Position Sensor when I was removing all the wires that dealt with that for my T56 Swap.

And yea, the Key on helps..
