Default engine and trans swap

I have a 98 gc and a 94 gc and am going to do an engine swap along with the trans and tc what all would I need to change from the 94 to my 98. The 94 has a front pass wreck and the frame was bent. The engine is fine with no damage. Any help will be appreciated. I am doing the job 4th of july weekend. Thank you

The engine's use different PCM's, and the tranny's use different TCM's. A lot of the harness might be different too but I'm not sure. Someone with more ZJ experience, and electrical knowledge will help I'm sure.
