Running lights out

[KLedder]

On my way home last night towing my car trailer I realized my running lights were not working on the trailer. Brake lights and blinkers still work though. I got home an unhooked the trailer and pulled out the test light breifly in the dark and cold driveway. Found out there is no power coming to the 7 pin connector on the truck for the running lights. Rather than start tearing into the harness in the dark I decided to wait until today to dig in further. Short of tracing this back foot by foot through the harness anybody have any guess' as to what might be wrong. Any TSB's I should know about. I figured I would start by checking all the fuses and go from there. Kind of odd as I checked the lights before I left and they all worked.

Found it... blown fuse for trailer parking lights. I wouldn't have guessed they had a seperate fuse just for the trailer parking lights.

Well if I had read your post earlier, could have told you. It's actually one of the better safety features I have seen added to our trucks.
