So, the wire harness for the 02 f4i has been discontinued. Is it possible to take from another 01-03 harness to replace mine. One of the previous owners went ham on the wire harness in the headlight area my guess is wiring aftermarket directional. Same thing with the rear tail section my guess the same they put a fender eliminator on. Please any help with this wire harness would be much appreciated.

 

In theory all of the 01-06 harnesses should be the same, I am not aware any any significant changes that should have affected the harness.
I could however be wrong.
