HELP No Running lights on trailer
The running lights and marker light on my trailer no longer work when I connect to my 2008, F150 4x2 Supercab, XLT, 4.6 V8 Auto with Tow package. Brake and turn signal work fine.
The running lights, all the lights work on the trailer work when I connect to my Chevy so I know the problem is in the F150.
I have confirmed the ground to the 7 pin and 4 flat connector is good so I am thinking it must be a fuse or relay. Which specific fuse or relay should I check or replace?
Or is there another area or item I should check?
Thanks for you help.

Hey Texas Welcome to FTE and the 2004 - 2008 F150 forum.
Stop guessing and get one of these to troubleshoot electrical concerns. You can at least start at the connecter and work back til you find the culprit.
