connecting newer xj to the rear mj harness???

[Mnh88xj]

i have an 89 comanche that I'm completely rewiring with a harness from a 94 cherokee. The newer style cherokee harness by the kick panel doesn't plug into the original mj body harness. my question is should i use the cherokee rear harness or does the newer (92ish comanche)rear harness plug right in, or should i splice some wires by the plug ..or maybe somebody makes an adapter??  any help or insight on this would be appreciated. thanks
