I just rewired my whole car.
I went with a K&R unit.
I was very impressed!!
It came with every single wire and they were all labled and color coded.
It also came with a huge laminated diagram that was very easy to follow.
It comes with a sweet switch pannel also.
They also have great customer service.
I found them at a MOPAR show.
I went with the super duty.
It is not the cheapest by any means, but in my opinion its the best!
Here is a link to them.
