Just finishing a '64 Chevy C10 using EZ Wire. Good quality wire and insulation. Install just takes a bit of patience. Read the first 4 pages until you are comfortable with what is being said then get busy! Only thing I added were relays for two electric fans powered by two unused circuits (power windows and electric nut crackers??). That way if one gives out the other one trucks on!
Good quality you pay for once. Cheap junk you keep making payments on.
