After the wiring and installation comes the more time consuming process of shaving the door handles. And that is actually the shaving part. We tried two different methods on this Camaro. On the passenger's side, I cut out the keyhole and the handle as one piece and created a patch panel the exact size then MIG welded it in. On the driver's side, smaller patch panels where the door lock and handle used to be were fashioned and welded directly over the holes. The later was the best method. I'll explain why in a minute.
