PCM Wiring Pinout

I am swapping my 2.5L for a 5.3 ls motor. I want to eliminate the wires in the Jeep PCM not used. Anyone know where i can get a pinout chart or better yet, a chart telling me exactly which wires to take out? Thanks in advance.

You have to get the pin out for both. Leave the bulk head plug from your jeep in place. When you have the pin out for both start splicing the new wiring harness to your Jeeps bulkhead wires. I found the pin outs I need just using Google
