so i just bought an 87 camaro for my first car but needs some serious wiring work.. the main problem im having is im not getting a spark witch apparently could be a number of things.. the engine is actually an 1989 s10 v6 2.8l with multi port injection, i have both the 87 and 89 computer. alot of the wires have been randomly cut and tied off to others (was the old owner lol). so what i think im looking for is a new wiring harness but i don't know enough to go buy one my self. do i need the harness for the 87 body or for the 89 engine? i would assume there to be compatibility issues between the two... any ideas or tips or just about anything could be a big help, Thanks.
