1986. 4.0 SWAP

[Jeepjeff859]

So I am getting to the electrical part of my swap and I am toying with the idea of getting the rear harness of my donor jeep and making the wires longer to reach the back of my jeep instead of adapting the harness to my old rear harness, would this be easier than adapting it?

Need more details on the donor?  XJ? Another MJ?

 

If you're using an XJ donor, you're better off making an adapter plug harness.  There's a DIY guide on CC about it and it's not hard if you have a basic understand of electrical.

I'm using a 1995 Cherokee as my donor, and I'll look up the guide

Also, feel free to look through my build thread as I've tried to compile a pretty good collection of pictures with explanations of how I did it.  You can also PM if you ever have a question.
