Help (Towing Question)

[ghettoracer]

I have a Ford factory hitch on my Expy and its a Ford 7RV blade on my outlet. I am using a 7RV to 4 pin adaptor connector and the brake and blinker lights work but the running lights dont work on the trailer. Im thinking its a blown fuse. I looked on the Ford fuse diagram and doesnt tell me which one it is for the running lights on the tow package. Can someone please help. Thanks!

I just checked all the fuses they seem to be fine, there is no power going to the trailer marker prong on the 7RV outlet. Any suggestions?

Unfortunately it sounds as if you are going to have to trace the wires and see if there is a bad wire that is grounding itself to the car.
