Anybody try a "painless wiring harness"

I used KWICK WIRE .... ( bought it a while ago at a meet ) cost around $200 for a 16 circuit set up..... I changed everything including the connectors on both ends. I didn't want to use 40 year old connectors....Originality to me, is not as important as unwavering functionality. all of my connections/connectors are soldered. It was pretty easy, time consuming but easy. DO NOT IMAGINE FOR ONE SECOND that you can do this in a weekend ( talking about changing everything out OR wiring from scratch).... THIS is NOT a weekend job not matter what product you use. PLAN ON a full 7 days 8 hours per day to do this ( this includes "frustration time" and some BEER time) to do it RIGHT.
VERY MUCH HELPS is you have the original schematics for you year & model....Ma Mopar does some funky confusing stuff to save wiring "chin bone connected to knee bone" type stuff and the switches and lights are engineered to be connected like that. so if you plan on using original switches GET A SCHEMATIC BEFORE YOU START and spend a few days tracing down what goes where.... break it out by circuit makes it much easier

WARNING: If you "slap it" together and dont make solid soldered connections or properly bundle/friction tape the wires....YOU WILL PAY for it later. I have seen a few guys "rewire" their cars using butt connectors, crimp connectors and twist & tape splicing ...they got in done in a day & a half....... headlights dont work steady, tail lights & brake lights are random, radio cuts out, car has trouble starting.....
taking the time to do it right, is well worth the time spent in the long run...ya your car will be down for a while PICK a rainy week and you wont miss much

most of the "kits" are about the same in quality, so SHOP for price within the reputable brands.

OR you can pay $3600 to have an "original MOPAR harness" made from your VIN. It will have all the correct connections all soldered and correctly bundled...but that is a
chunk o change for a non concours vehicle

good luck
