I have done direct change outs of engines and transmission but not when major electrical is involved? I also have dealer service manuals on both Jeeps that I purchased just for this project. I no it would be smart of me to sell my 89YJ and just purchase a newer one with a 4.0 in it but I like my Jeep and want to hang on to it.


89 YJ, 3.5" Black Diamond Lift, 33" tires, 8000lb Warn, 4.0 91 XY engine swap.
