I bought a BBK 58mm throttle used off here, and it is a 94-97 throttle body for my 93, only difference seems to be that I can't hook up my idle air controller(IAC) to it cuz the harness's are completly different, is there a way to make this work? I was thinking, what if I were to just pull a 94-97 IAC harness of a 94-97 Z28 from a junkyard and cut my current harness off and splice in that one.. would that work? If not what do I have to do to use this throttle body on my 93 Z28??

 

anyone know?

 

Yes it will work if you use the newer iac harness the wire colors will be the same. Thats the nice thing about driving older gm and not the blue oval.
