My guys i got z 1988 vert. Wire harness was cut up pretty bad. Belive the person who owned car before me was running a carb. I believe the computer in there is for a 305 tpi. Im not sure if i can use it for my 350 tpi swap or should i get a 350 ecm.. Im looking to purchase a wire harness that will fit and work for a 88 iorcz. Thanks alot. I have purchased numerous parts from this site so let me know... I'll go to the wrecking yard probably tomorrow to see if i find something good but until than let me know..!!!

Thanks guys

 

The harness you can use from a 88 or 89. The only difference is the 89 will not have the cold start injector.
if you post the letters off your computer chip I can identify it.
For a harness you can adapt one from speedway motors.
