I have been looking to purchase a new wiring kit for my 41 plymouth coupe build . From what i have been reading it is a good idea to put most of the circuits on a relay (like most new veichiles ) . I can not find a wiring kit that comes with enough relay's to power all the differnt circuit's . 3 or 4 relay's is the most i have seen in any kit . For the money you would think that these kits would be a little more updated . I ripped out the fuse box from an 98 jimmy that i scraped and in the process of figuring out all the wires for it. Hopefully i can utilize it with the relays.
