I installed the "Painless" kit. Although it wasn't painless.
I have to admit though that I had never wired a car before and in about 4 months I did it. I recreated original harness' with Molex connectors so I could unplug any harness to work on it. This will test your patience but I made sure I did something every weekend, sometimes I broke something but in the end I got it all to work.
I used there generic 12 circuit harness, plenty for my Mopar.
Take care and sounds like enough guys here can help you out. I know I used the forum for that (DC.com)
Take care
Michael
