Are the wiring harness for a 99-00 and an 02 the same? any help is appriciated.

 

01-02 wiring harnesses won't have the EGR wires... as far as similarities to run the car... yes I believe they're all the same (Probabl a diff beteween M6 and A4 harnesses though?)

Basic operation though they should be similar enough (other than the A4/M6 issue)

 

ahhahahahah yeah EGR uh what is that....lol that thing is long gone.............its on a turbo car.......thank you for the prompt reply horist
