Jeep connector pin extraction tool

Got a 2004 Grand Cherokee that needs some harness work. Rather than splice and solder, I'd like to replace individual wires between connectors, so I need a pin extraction tool(s). Problem is I can't find much info on the make of the connectors throughout the vehicle, nor what type of extraction tool would be required. First efforts are for the door and shifter harnesses. What do I need for those?

These are the electrical pick that we used in the assembly plants when repinning connectors.
