Need help on motor swap.

I have a 1989 Jeep YJ and I am putting in a 89 Cherokee 4.0 motor in it and I need a little help on the wiring side. I know that this motor is less popular but the price was right. so anyone out there help me out? what wires need to be spliced into the wrangler harness. Thanks

OK just a update... I found a 94 cherokee 4.0L motor and am getting ready to put it in . 4.2 is out and 4.0 is ready to go I know I will need to do something about the CPS maybe the hesco one. my only concern is the wiring as the harness was cut off at the firewall connector. I have searched and found a few posts about the wire conectors bur most list the terminal number. is ther anyone that has the color to color connections that need to be done? I looked at the motor swap tech posted here on the forum but a lot of the links are dead.
Thanks

OK my wire colors are a little different, any body have the diagram from a 87 wrangler? or are they the same colors?
Thanks

H2 on the engine harness, G5 on the IP side. It depends on how you rewired it to make it work on where they are at.
