My '86 Firebird had a minor engine fire in the coil and EGR area. Due to that, I'm looking for a replacement engine harness. I don't require one that is complete or pristine (although that would certainly be preferable, lol) but I at least need the portion that covers the egr and throttle body area. I'm not sure what years will interchange, but the egr pigtail and IAC pigtail may have changed in the 3.1L years.

 

I've got 2 harnesses that should work for you; depending on your ride. Both of these are ECM harnesses,... they do NOT include the ENGINE harness or the Headlight Harness.

1985 MPFI, Automatic

1987 MPFI, Stick

I believe both of the harnesses are pretty much still fully intact. If your still looking and are interested just get back to me and I'll send some pics.

 

Yep, still looking. I believe the '87 harness would be a better choice due to my '86 being a 5-speed.

 

Sorry so slow,... i had to step away from the world for a while.

This morning I pulled-out the harness for verification; it IS an 87 harness. My investigation was VERY limited as I'm short on time right now, but i did spot a couple things; full harness from C100 all the wat to C207, the positive battery cable was there, the HEADLIGHT harness is NOT included, & it looks like the HVAC harness connector plug has been removed. I know its been awhile so i wanted to at least W//B to let you know it's available. if your still looking and need more info just send me a PM and I'll stretch out the harness and get you more details.
