Hi, Cohort!
Wouldn't surprise me if you had to take it to a Crossfire dealership. My '04 Coupe was whacked by a deer last March (left front panel, door, headlight assy., mirror) & the body shop ran into the same issue. I had to drop it off at a dealer where they reset the ECU (I think.......they reset something!).
Why did they have to lengthen wires?
