EZ wiring harness on a 1963 Plymouth Valiant??

I've installed the harness but in a 71 Scamp. It will work in your car just fine. It is not a 1 day job and honestly took me about 3 weeks to do it. I laid the entire harness out to where I wanted each wire to go to. I ran thru the FSM wiring and double and triple checked everything, all before I cut my first wire. I also bought a good crimp tool and all the connectors, heat shrink, and anything else I needed ahead of time. Take your time and do it correctly and you will be very happy! Like Bob said, if you run into any problems give Sean a call he is great!
