Can anyone tell me what this plug goes to? It's the cut one in the picture on the far right side. The other three plugs go into the ECM. I got this with a TPI set-up purchase off ebay

I have a chilton manual, just haven't had a chance to trace wires to see what it may be, I was hoping someone knew already.

It came out of a 1985 Iroc camaro TPI 305.

Thanks for the help!

That goes to the dash harness. It connects to the ALDL plug, speedo, TCC control and a few other things

Thanks!

I have a question, is the ADL plug the thing that you plug the code reader into?

I'm putting this in my 82 corvette

Yea, thats what it is. Assembly Line Diagnostic Link. Too bad its used alot more OFF the assembly line than on it.
