Re: 86 engine tpi
I have a tpi harness from a 1987 GTA if it will help, or are you wanting to stick with the big cap HEI?

Re: 86 engine tpi
FYI: 1987 and 1988 Engine bay wiring is NOT the same !! 87 Uses and ENGINE and a seperate ECM harness,... the 88+ cars use 1 HUGE harness for the Engine AND the ECM wiring combined. ( Headlight harness also changed from 87 to 88. )
I've got an TPI ECM harness from an 86 IROC automatic. You can see the details here:

If you need an ENGINE harness,.... I should have one of those too, but I'll have to check into that t be sure.
Send me a PM that includes your ZIP for a shipping quote if your interested.
