I posted this over in the electrical forum but figured I would give it a shot over here too since its a '05 and there are way more people that check this one out.

I have lost power to my tail lights on the factory 4 pin hookup on my '05 XL. Everything else is getting power. I looked it up in the book and all I could find is relay 201, it seems to be OK, swapped relay 202 over into it (fog lights) and it didnt fix my problem. Is there any other fuse associated with the tail lights on the trailer plug? My tail lights on the truck are working fine. I used my neighbors 16' trailer the other day to pull a bush hog and I think his lights must of shorted something out. Any help is appreciated.

 

Did you change relays 201 and 202 inside the truck "left kick panel" or did you change the ralays 201 and 202 in the right drivers side motor compartment??

 

inside the truck, I dont have a 202 in the block under the hood.
