I am restoring a 1960 Plymouth station wagon with a heavily damaged wiring harness. 40% of the harness has been monkeyed with (at some point someone added a trailer light plug, AC, fog lights, home made voltage regulator, and a lot of other mess). The other 60% of the harness is cracked with wires cut or missing connector ends. The current harness is basically trashed. I was looking to totally replace the harness, and update to a harness with fuses, electronic ignition, and alternator. So far the best option that I have found is this Painless 1966-76 Mopar Harness https://www.painlessperformance.com/wc/10127.

Has anyone else had to replace their entire harness?
What suggestions do y'all have?
Just curious, does anyone know why the original harness had no fuses?

I also got xtra long due to worry about the rear tail lights. I like the painless stuff, I am going to do some documentation on mapping as that will be the pita...

it had no fuses because it was 1957 ... people didnt put giant speakers, electric fans, electric fuel pumps, crazy dvd players and aftermarket stereos with amps in their cars

they had some cirbuit  breakers on various parts.

I bought a f.s.m and all the correct color and guage wires and built my own. The total harness only cost me about 200 dollars.

I was very happy with the American Autowire harness that I installed in my '55 wagon.

Yeah i need to replace the whole front to back wiring harness on my 58 Belvedere. The wires are so brittle from age I'm worried about just moving them around will snap them. Also its been spiced at the lighting spots cause my car has been converted to 57, and then back to originality as a 58 again. I'm probably going to get the universal 21 circut for Mopars by Painless wiring harnesses. About 500 bucks, not too bad.
These cars (also other makes in the 50s) dont have fuse boxes. Personally, i think its unsafe to not have a fuse box, its like just asking for shorting out/possible electrical fire to happen. Fuse boxes started in the 60s. Just another reason why i want that new wiring harness so bad, it has a fuse box in it.

Jackie: this video is good to watch even though you are installing a new harness. He is an automotive instructor and car restorer. Yes, the accent is thick, but after a few minutes you will get used to it. The steering wheel video that he made this year is good also.

Wow, i sure wasnt expecting to see that 57 Plymouth! Went to the video, thinking it was of some other car rewiring. When i saw that 57, i'm sure i jumped. Thanks Marc, saved this video, should help me out when i get to this stage.
