88 tbi 350, with 93 454 tbottle body with adapter plate.
I put a 1993 454 throttle body on my 88 350 tbi pickup. The connectors for
the IAC and TPS are different though, i was able to splice the tps one on
fine. But with the IAC one i have no way of knowing where
green/white,green/black, or blue/white, blue/black go. The connector on my
88 harness and tb is square, the connector on the 93 454 tb is rectangular.
Anyone ever done this swap? or have a 93 454 truck and can get me a picture
or describe to me which wires go where etc.
this will sound dumb, but look for stuff on line, like 454 throttle body wiring guide, best of luck with that
