1991 GM Sierra Main Engine Wire Harness?

ldeneale · September 10, 2006

We have been looking for a main wire harness for the engine of a 1991 GM Sierra V8 5.7 350 gas engine. If anyone can help it would be great and take a load off. The Chevy house said it would be $1200.00. I can't afford anything that expensive. Thank s in advance for all the help!

Junk yard would probably be your best bet. How bad is it damaged? Connectors and wiring can be repaired by the dealer to like new condition.

If you still have the old harness and it has all the connectors on it, I'd say get a wiring diagram and re-wire it yourself. It'll save you a TON of money.
