i have heard that same year models work together i have done a swap too but i used a stand alone harness so i didnt have to deal with most of it

I bought a 2001 v6 spd camaro and swaped a T/A 98 LS A4 into it. i used to whole harness form the T/A from head light to tailight when i did the swap.

im not sure if you can intergrate harnesses. like your stock chassis harness and a LS engine harness??

THere are three general harness's that are in your car.
Chassis harness
Engine bay harness
Engine Harness

I would assume the same year and same model would swap, assuming you swaped a LS engine & engine bay harness. then i would believe your chassis harness would be fine.

I re-wired the LS1 Harness for my swap..click on the part in my sig that describes my Engine, it will take you to my Swap Thread that has that info..

i see how your wiring harness has 3 plug ins for under the dash what year model wiring harness do you have?

I started with a 1999.. it had the Blue and the White, I added in the Black one. Read through the Guide, I mention where I did that.

i was told by a guy i know that he thought if i go back to a 98 harness that it would be all plug and play with my harness on the car since its a 98. does anyone know if this is true or will i still have other wiring to do to make it work if so please tell me what and explain if u can.. one other ? is if i go with the 98 harness will i have to use a 98 pcm cause a buddy of mine has hp tuner for a 2000 and i was gone go with a 2000 computer so we could tune it with his.. will it work ive heard stories about 99 up pcm not working with 98 harness but dont know all the details... Thanks

i've heard from someone that a 98-98 swap is plug and play. Ask a member "Chets Bird" He swapped a 98 ls1 in his 98 v6
