I found swap instructions for a 93-97 A4-M6 swap. They used the A4 harness and made it work. Is this possible to do on the 98+? i can get the pigtails they needed, but i dont know if the wire colors are the same.

Anybody know????

 

Somebody has to know this???

 

I don't know if it's the same but one way or another it is possible if you splice into the wires b/c you can use the same pcm with a different flash file.
