1997 TJ 2.5 to 2001 4.0 conversion wiring issues!!!

I have been working on converting my 1997 2.5 TJ to a 2001 4.0 for a while and I have everything installed except for the wiring. I had to go from a 30RH to a 32RH to work with the 2001 4.0L i bought. I have welded new shackles on the frame and made everything work except the wiring. I cannot get it completely finished. I have all the wiring diagrams for a 97 and an 01 and I can't quite figure it out. I am hoping someone has done something simmilar and can help me figure out what wires go into each harness to communicate properly. Any help is great, thanks!

More info on exactly what you have done might help. For example, are you changing PCMs? Are you trying to use the original wiring harness or one from a 2001 4.0? How far have you gotten & what specific problems are you having?

Here are a couple threads with similar changes that may (or not) help.
