Default Differences in engine & underhood harnesses

Can anyone confirm the difference between Camaro vs Trans Am wiring harnesses for LS1 cars? I have a 2002 Trans Am and I have no engine harness or underhood harness. What would work, and be CORRECT? I assume Camaro harnesses will not work because of headlights, or am I wrong here? Are there provisions for headlight motor circuits tucked in the Camaro harness? I'd appreciate it if anyone could give me a run down on the differences of LS1 F body harnesses. Thanks!

-Dan


PS... first post in the LS1 section LOL.

the engine harness's are not different. the underhood vechicle harness's are different. the main difference is the headlights. the rest of the stuff is the same.

So the engine harness is the same all through 1998-2002, other than the difference of A4 vs M6?


The Camaro underhood harness does not have provisions for the headlight motor circuits of a Trans Am?

1998 Engine harness is specific to '98 cars as they use analog inputs for dash and PCM. '99+ will pretty much interchange. '01 and '02 harnesses will not have EGR connectors in them but will work just fine in a '99. A4 and M6 harnesses are specific also.

Body/engine bay harness is specific to Camaro and Trans Am, they will not switch. I possibly have the body/engine bay harness if you need one, let me know.

Thanks Tim. Reason I ask all this is because I bought a 2002 Trans Am that is missing the underhood harness and engine harness. These are fairly inexpensive so I want to get them right now, it would also be nice to put the windows up LOL. I just bought a '99 Camaro underhood harness after being told that the Camaro harness did have the circuits for Trans Am headlights, but it would be just a pigtail and a separate headlight harness for a Trans Am would plug in. I guess this is probably incorrect but I can't verify because the harness isn't here yet.

Do you have any harnesses for a 2002 TA?

front harness are different but can make them work, engine harness's are the same between the camaro and firebird but the years are different. stay away from 98 front end harness and the engine harness. 98 **** is bascally a year all on it's own
