*Project* 1997 XJ 4.0/AW4/NP231 into a 1993 YJ
 

I recently purchased a 1993 YJ which has high mileage and %-speed tranny issues. I have located a complete 1997 4.0/AW4/NP231 all bolted together from a 1997 Cherokee. The biggest problem I have found so far is that the donor vehicle was crushed without the seller removing the TCU/ECU/wiring harness. What challenges am I looking at in order to complete this swap?

Any and all comments are appreciated!
