The Painless Wire Harness is an excellent product but it's not an easy or quick task. Painless makes it as easy as I think can be but you need to allow sufficient time to work through this in a very methodical manner. My project car is a 1963 CJ5 where the original (fuseless) wire harness had a major meltdown so it needed to be replaced. Now I have a harness that should last a very long time. The 12 circuit harness has more electrical options then I could use on such a simple car. Now I have power to wire future electrical accessories such as a radio, cigarette plug adapter and maybe a cabin light. I would highly recommend this wire harness to anyone that needs to rewire their car.
