yes i think there is a fuse in the fuse panel but id have to check. If nothing else you can temporarily wire up a 4-flat or whatever connector you need by tapping into the taillight wiring. My truck has the plug in the bumper and it also has a secondary plug under the truck just in case. Never had to use it though.

I had the same problem when I had my Cheby Avalanche, I actually traced all the wires on my bass boat trailer and everything looked fine. Then I hooked up to the former Mrs. Hammer's Grand Cherokee and had lights, turn signals, etc.
The owners manual didn't list a thing for trailer lights, so for the hell of it, I just started pulling fuses. Came across one that was blown, a low capacity one, was either 10 or 15A. Replaced it and everything worked fine...

No trailer lights
I had a similar problem with a boat railer and found that I had a bad groung wire on the truck. Assuming you have power at your truck plug, you can check the ground by connecting a piece of wire from a clean part of your frame to a clean part of the frame of the trailer. Keep the trailer plugged in at the same time. If lights come on when touching the wire to the frame, new ground wire to truck frame would be the answer. Sometimes when you have a bad ground on the truck, the trailer gets grounded through the hitch but that is if there is no grease on the ball, no rust on hitch pin, etc.
