Trailer right turn/stop not working problem

2023 Power Wagon. I was given a very old boat recently. The trailer wiring was sketchy and the right turn and right brake light was not working. It needed to be upgraded anyway, so without checking as to why, I rewired the trailer with new led lights and new wires for a 7 way. Right turn and stop still did not work. Tested the new trailer wiring and it was good. I also have a Putco light bar on my truck and recently the amber right turn on the bar has stopped working so I thought it may be Putco wiring harness causing the problem. I removed the Putco pigtail behind the bumper and put the plugs back OEM. Again no right turn signal or brake light on the trailer. Note the taillights on the truck work as normal. A lot of assumed goose chasing, but in the end there is a lack of power to the right turn and stop wires to the bumper female 7 way that I could have discovered if I had just tested the truck's 7 way connection to begin with.

So again the trailer running lights work. It is only the right turn and stop wire that is not getting power from the truck. I'm not getting anything obvious out of the manual, so the question. Is there a fuse location that would only effect the towing right side turn signal and stop light?
 
Is there one for individual sides? Hmmmm. All I know and it may help if you are chasing wires, Yellow wire is for the left side. Yellow has the letter "L" (left) and Green wire is for right. Green has the letter "R" in it. Does it have to be the 7 way? You could slice in a 4 way into the trailer harness with out chopping off the 7 way male. Most of the newer Rams have both 4 and 7 pins at the same location.
 
Yes, F81. I just figured it out. I had no fuse in F81. I have never pulled it and it would have been there before as my PUTCO light bar right turn signal was working when I installed the bar. I do know that when my truck was in for warranty work on my windshield washers and recalls, it came home without the factory fuse puller in the fuse box. And it would have been sometime after that when I first noticed the putco bar right turn not working. All I can think is someone pulled that fuse for some reason or by mistake. Easy fix though.
 
I like this when there are positive outcomes to a question/problem solving. I'm sure there is enough "experiences" 'tween us all to make a hell of a truck.
 
I know older thread but on my 2022 ram 2500 53, and 81 fuses check good. No signal on one side other works. Run lights work.?? Any ideas.
 
Oh checked the 4 pin connector as well no right left works? Traced back to wire connector no signs of any damage.
