does anyone live in north jersey i am in west milford my mechanic has had car with all parts to complete job for 2 weeks he is stuck on the wiring any help would be greatly appreciated

what's he trying to wire up?

3800sc 2000 gtp into a 1987 fiero gt using wiring harness from 3800sc and comp. car is auto.

Which thread do you want your question answered as you have 2 (I think) asking the same thing?

Don't you have to piggyback another ECM to the harness ? The schematics from GM should use the same/similar colors of wires, but I've not personally been involved with any V6 swaps hands on that is.

to this thread thanks. sorry but its driving me crazy
