Appreciate the responses, guys! Hate to hijack a little..

You'll use 90% of your jeeps harness and just add some of the donors into it. As for schematics I used fsm's for both my jeep and donor. They are by far the best in my opinion. Do not let the wiring scare you!
I'm trying not to let it scare me, but it always looks like the multicoloured spaghetti of doom.
I'm thinking that keeping the AX-15 will keep some of it even simpler. I'm not a big fan of having my gears chosen for me, hah.
One of the things I can't find clarification on, is that with using the V6 bellhousing and the Jeep AX-15, are you required to change the flywheel to the Ram 2500 one? Or can I retain the Jeep flywheel? I keep reading about using the Ram manual flywheel with the AX-15.
I kept looking at wiring harness prices, and I just absolutely cannot stomach the cost of a minimum of $700 for very similar wiring.. The idea of this swap is to do it on a decent budget because it uses a lot of the same parts to keep it MOPAR, doesn't require new gauges or a possible 2-piece driveline, fly-by-wire, etc, like the Chev 5.3/etc does. I think with such dissimilar harnesses I could see paying, but indeed, all my research indicates that even many of the wiring colours remain the same.. depending on your donor.
Thanks for reading the whole thing. Good luck with yours. Do a build thread when you get going on it.
I used FSMs for both vehicles, and wouldn't have done it without them. They are simply the most complete wiring and pinout diagrams available. The wiring harnesses were remarkably similar between the two vehicles, and really the hardest part is getting started. I stared at the harnesses for a long time before I actually got to cutting. Get familiar with the two harnesses and make a plan on what it should look like when done.
I did mine a little differently. I used the Dodge engine wiring harness and spliced in the few Jeep connectors that I retained (fuel pump, speed sensor, 4WD sensor, etc.). It made more sense in my situation to use the Dodge wiring instead of the Jeep because my injector plugs were different, adding the auto relay and fuses, park/neutral switch, etc., etc. Regardless of the method used, you need to trace every wire to make sure you know what it's going to.
There's more than one method available to remove the fur from a feline.
I absolutely will. I have the build thread up for the one ton swap already, but I'm not sure if I'll create a new thread for the motor swap. We'll cross that bridge soon enough! The truck is in good enough shape that the girlfriend is actually going to drive it for a month or two while I get all my ducks in a row.
FSMs it is. I'll have to source them. The ALLDATA diagrams seemed lacking, honestly.
I believe (keyword) it may make more sense in my case to use the Jeep harness for the majority of it, as I am retaining the manual transmission and have the 4.0L currently in.. But right, as you said, more ways than one.. I'll make sure to label every wire in the harness regardless.
I have other questions, but I'm blanking on them right now!
