Hope this helps you identify things.
The panel under the dash has 4 black relays at the bottom
from left to right
1st relay is Trailer Tow Relay for Right Turn Signal
2nd relay is Trailer Tow Relay for Left turn signal
Now if you can verify they have power andd are clicking when your turn signals ar eon that says you are getting power to the relay. I also can verify that you ar elooking for a 20 amp fuse and may even be a fuse link off of the battery positive post. A fise link looks like a thick wire but is actually a one time fuse. This part is just a guess.
I know you said all fuses are good but can you double check fuse #1 20 amp that I have circled in the 2nd picture.
