1993 yj with 2.5,ax5, converting 4.0 HO from 1994 cherokee

I have a 1994 Cherokee with a 4.0 HO, auto trans. I want to put the engine and trans into my 1993 YJ Wrangler. My Wrangler currently has, 2.5, ax5.
What is the best/easiest way to do it. I don't know where to start. If anyone can relay the details, I would greatly appreciate.

My sons and I did this same swap into a 91 wrangler. It is fairly easy to get the 2.5 out and cut off the motor mounts. I was able to reuse the old ones. Bolt them onto the 4.0l and set the entire drive train into the wrangler. You can then weld the mounts to the frame after you get everything lined up to your satisfaction. The most difficult part of this swap for me was the electrical. I brought everything from the cherokee: (ecu,wiring harness,tranny ecu) and put them into the wrangler. The 91 wrangler had a split bulkhead in that 1/2 of it was for all the front lighting. The other half contained the few wires you will need to get things to work. This is the part that took a lot of study and searching. Not everything I needed was in the firewall bulkhead. The 91 YJ had some wires coming through a fire wall grommet to a different connector. Get online and read up. This is a common swap. It took chiltons and haynes from both vehicles and a purchase of a wiring cd for both vehicles to get all the wires I needed for the odd stuff like 4wd lights, backup lights, fuel guage, and other sending units etc. I also had a cable run speedo and took out the electric sending unit and kept the mechanical unit. I replaced things like water pump and belts etc. I did not have A/C in the wrangler but kept the 94XJ a/c comp. intact just in case I decide to add later. There are many things not included here. I did not document anything as it has been done already, but if you get into a situation you can find the answers here. Good luck. It was well worth the effort.
