I wired my 1954 Chevy Belair bumper to bumper using a new Painless wire harness. Also converted it to 12 volts. Never wired a complete car before. Had numerous questions and the techs at Painless were a great help. Would I do it again, it would be easier the second time around. Considering a rewire on my 1955 truck. It takes alot of time and patience. Good luck.
