Help with fuse, no trailer lights?
I have no left (or right, can't remember) trailer lights. Test light on the plug on back of the car is dead on the left side, and this fuse panel labeled left has no power either with a test light. The opposite side works fine. All fuses are good, even swapped some around. Checked under hood too.

Re: Help with fuse, no trailer lights?
Not sure what a junction plate looks like, there is a mess of wire bundles under there all with factory plugs. Plus the trailer harness runs up the left side of the truck, not the right?
I did some further test light work. The 15 amp fuse is the left brake turn (for trailer) so it's a shared circuit. The blinker works, but the brake does not. The right side (red one underneath blue one) works fine, lights up for blinker and brake.
Any other suggestions? Thanks!

I know on the four pin connection it has a running light a left turn/brake. A right turn/brake and a ground
I am going to check my wiring diagrams and see if the trailer harness routes to the junction plate under the right rear fender or not and see where it goes if it doesn't
