Could not find a harness to suit my 49. Stock with a generator, 12 volt and turn signals. Next choice? Made my own. If you can trust the crimps you make on the terminals its a piece of cake. I used the schematic from the shop manual and ran one wire at a time. As an example there are only a few wires from the fuse block forward and the longest is less than 4 feet. Under dash is more difficult because of location but it would be that way with an aftermarket harness anyway. I don't care about originality.
