yeah, back in the "old days" (or old cars, since the old days are too old for me ) you could repair that real easy in your garage..... but then again those old cars didnt have miles of wiring and 30+ computers in them
Just be glad you dont have a volkswagen, their harnesses are hand made and only come in complete sections.
I.E. if it was in your engine compartment - whole engine harness
Somewhere inside the car that couldnt be repaired - whole body harness, from the dash to the tail lights.
I replaced both on one car, took over two months just to get the new harness' which cost over 4k and then had to pull EVERYTHING out of the car to replace the body harness .
