The best harness for a civvy 12 volt system is one you design, tailor directly to your jeep and build yourself. Body work and engine rebuilding are much more difficult tasks then wiring harness building. There is tons of info for you to delve into and arm yourself for a very nice job. There are several ready made harnesses out there you can read the reviews on. Visit my m38/M38A1 specific web site discussions on this topic at www.willysmjeeps.com

Same situation I was going to buy a 12v harness but found a M170 mis harness and used it and built the sub harnesses from trailer harnesses available on epay worked great

Bought some connectors from Saturn surplus to build my harnesses. Worked out great. Matched up with my ign switch and panel with some wire work.

Download the wiring schematic and understand the harness. Pretty simple but starting with an original harness helped. I just rolled up the slack in the M170 rear harness. Then spliced in the trailer part.

BTW I put a 12v single wire double pulls alternator on off epay $58 works great. Anyone wanting to re convert to 28v no problem the rest of my harness is as 28v was
