Engine Swap

What all would it take to swap a 4.0 out of a 03 Wrangler into a 96 XJ with a 4.0

Grab all of the electronics and wiring as well, to make your life simple. The 2003 will have distributorless ignition, which your 1996 does not (which makes the ignition setup different and the ignition control in the PCM different. And the wiring will differ as well - since you have three ignition coils vice one.)
