Sorry, I can't answer that. I only have the schematics for my truck, a 2016.

 

I posted 3 pages in this thread above #19,#20,#21, from a '19 I know the fuse numbers change but was curious if the wiring logic changed between model years.

 

All of these fuses that you noted I checked...physically pulling the fuse out and visually checked it or int he case of the 34-36 fuses, i checked continuity. All were good.

Cool. I'll check that in a few.

 

Ok, I've had a chance to compare these schematics with the following observations:

Diagram 1 of 6
Everything is the same (circuit numbers, wire colors, and component pinouts) except some of the connector numbers are different.

Diagram 2 of 6
Everything is the same except for the addition of a Trailer Tow Alarm circuit (CAT13) to the TRM on the 2016.

Diagram 3 of 6
Everything is the same except for wire colors and inline connector number.

Diagrams 4 and 5 of 6
Everything the same except VBATT is a different circuit number and wire color.

Diagram 6 of 6
Everything is the same except for some connector numbers

 

OP, do you have a good scan tool or access to FORScan? There are a multitude of DTCs related to the TRM (Trailer Tow Module) and TBC (Trailer Brake Control Module).

 

I do have a good scan tool but I don't have forscan

Well apparently, that was it. It was plugged in but the one wire was dislodged within the connector. I jiggled it and the turns were working on the trailer. I removed the connector and re-crimped and its now working perfectly.

I really appreciate the help of everyone on here who without your inputs and knowledge, I would still be racking my brain tying to figure out what the heck is wrong. So Thank You!
