Is the scan tool route something I could get my dealer to do if I walk them through it? Or you have your own personal scanner? I was trying to avoid the extra wiring with resistors if possible but not really a big deal to fab a harness with them inline

The dealer can only add options that Chrysler has made accessible to them in the DealerCONNECT system. The particular options will vary depending on the truck. I've heard that early Express models have the option for LED tails and front signals because the black express group came with them. I have not confirmed this.
I use the AutoEnginuity tool that I've discussed in more detail in other threads.
Do tell....
See above.
the factory led tail lights have a signal wire that goes back to bcm to check if tail light are working. I saw in 2500 and 3500 they have a feature in bcm to disable bulb out checking because they usually add more lights for (police, construction, fire). But I have yet to see how to disable this in a 1500. Please keep us updated
On trucks without factory LED tails, adding LEDs will generate a bulb out warning because of the lack of current draw. The official solution is to add/cut a wire (2500/3500 only) or add resistors. On trucks that came with LED tails, there is the fault sense wire you mention. It checks the state of the turn signal and the truck will hyperflash if it thinks there is an error. If you replace them with different LED tails, you need to add relays to put the right signal on this line.
In my case, when I tested, I set the options for LED brake, parking, and signal lights. I had no hyperflash or warnings. I expected that this would make the truck behave like a factory LED truck and the fault sense wire would be needed, but it didn't seem to be. It's possible that it is an additional option that I didn't enable. Admittedly, my testing was with one light and not for very long. Once I get my new lights in, I'll reevaluate and if there are issues I'll either add resistors or try to find the fault sense wires at the BCM so I can add relays there.
Feed us baby birds with all the particulars when you can.

I made the adapters for the other side last night and since I knew what I was doing this time, took photos of everything. I'll post details once I can sit down in front of my computer as it'll be too much to do from my phone.
