2013 F250 Super Duty, when using the bumper trailer harness I have no right turning signal or break light
I have two trailer harness connection, one in the bed and the other at the bumper. Put a tester on both, one in the bed works correctly - one at the bumper has no indicators for the right turning signal or right break light. Do they run off the same fuse relay? Diagram for my truck is showing only one relay for the right side turning signal and break light.
