I have lost power to my tail lights on 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.

 

If you have no tail lamps, I would start by checking F10, 20 AMP.
This feeds the N.O. contacts for the TT parking lamp relay.

This is assuming that the S/T/.. lights for the RH and LH sides work correctly ( you made a note of : Everything else is getting power ).

This is also assuming that the parking lamps on the 7 pin, as well as the 4 pin are not working ( not just a problem with the 4 pin only ).

Good Luck

 

right, my tail lights on my truck are working, its only the 4 prong plug that feeds my trailer that doesnt have power for the tail lights. The brake and turn signals on the trailer are working. I'll look at it later tonight to see if I can find F10 and check it.

 

You were right, fuse 10 was the culprit. I dont know how I missed that in the book. Thanks for the info

 

b/c you don't cheat like me, by dowloading the PDF so you can do a search for the term you are looking for, rather then try to read what each one does !

 

good idea
