YJ Swap...258 to 4.0L

[John B]

I'm looking for any write ups or detailed posts where someone has done this swap.

I have several XJ computers,wiring harness's and fuel systems along with a 96 HO/AW4 to swap in. Need to decide which computer/harness/fuel system to use for son's newly aquired YJ.

Thanks!

When I did mine I liked this article. Also call Hesco in Al. I think they were helpful on the phone.

I considered doing it myself. I bought a wrecked TJ with everything I needed. Man it looks like a real PITA. All those wires. But hopefully everything gose smooth. Good luck.
