That should be for the 02 sensor signal wire.

Currently I do not no the year of the harness in the car. It was modified to fit the 93 body harness, was done by someone else. I believe it was an 89 if I remember correctly.
Man! This 'pin the wire to connector' stuff can be confusing, glad I have an unmolested car. Mine is a 89 gt stick so if I can compare wire colors for ya let me know.
I all so have a 91 stick computer harness stored in my junk er, parts room, I think I have the 02 harness. I will look later.
Why was the harness changed?
That could be a mess. Is it possible for you to pull the 02 harness out and look for a part number? Or maybe match up the wire colors to a diagram? Maybe time consuming but not impossible to fix.The car was a 4 cylinder and converted over. Then had a engine fire and well it got mended with another harness
The messy part here is that you don't know what year harness you have, so wire colors may not matchup. I believe the pinouts are correct, but again, without knowing what you have, hard to say which to do.
Do you know if the transmission harness has the plug for the NGS on top of the t5, and is that hooked up.
I might try this. Any way to test continuity from pin 30 at ecu to one of the three wires in question? You may need clutch in or t5 in nuetral (if the NGS is hooked up) to do this. If you get continuity on one wore, that's you pin 30 wire. Then it's a matter of which one to pin to.

NGS? Bare with me on acronyms. I know the only thing plugged in is the speedo cable.
Nuetral gear selector. It tells the ecu the car is in gear or nuetral. There's a switch on the t5 top cover, and one at the clutch pedal. They are wired in parallel and if open, you get a permanent code 67 and can't run engine codes

Yup.
I'd still test for voyage on 46 first though.
