I just purchased this harness.. its supposed to be for a 94 Firebird LT1.. It's 8cyl.. but the computer connectors are the wrong ones.. now i need to find out if this will work.. can anyone shed some light on this? thanks..

The second photo, the rest of the harness looks correct, but that is DEFINITELY not the right harness. All 94-97 LT1's had nearly the exact same harness with the same ECM connections. Whatever that is, it's not from a Firebird.

If you wanted to use that harness, you could probably get away with it by splicing on the correct connectors, but then you would probably have to do a LOt of repinning to get all the wires in the right place.

 

i've come to the conclusion that this harness will not work.. the injectors appear to be batch fire.. at least inj 2-4-6-8 are same color wires and 1-3-5-7 are same colors .. now i still have to figure out what this is.. so I can sell it.. cause im out about $150US.

 

I'd have to say its a 93 LT1 harness.

 

i think you're right.

 

Mid 90's V8 Cadi's had those same type of connectors for the PCM.

 

I doubt they had the same connectors where it connects to the chassis harness in the top left of the pic.

And probably dont have an opti connector, which i bet he can find on that harness.

 

.....there is an opti connector.
