I agree with the wiring. I just replaced all of the wiring in my truck, but had to reuse some of the wiring like the hazard harness. I made for a much smoother job than if the wires had to be spliced. I have the original 63 custom options book around here somewhere, il find later. The same hazard light was used in several chevy models, so looking for one in a car site might give more options, just beware of the possibly difference in connectors. If find the book and see what chevy says.
