Recently purchased 6.0L diesel 2006 F250 with approx. 99,600 miles. Haven't been able to get the tail lights on my boat trailer to light up. The turn signals, brake lights, and flashers all work fine. The wiring harness on the trailer has been replaced, but still no lights. The Ford repair folks say it is a fuse but none seem to be blown. Any Help?

Check these fuses first, have uploaded image for you.

7-PD CONNECTOR 2005-2006 VEHICLES

1. Check Fuses F1.9 and F120 in the battery junction fuse box, located in the engine
compartment, left rear side and Fuses F238 and F2.1 07 in central junction fuse box,
under the dash panel, left hand side.

Also I assume you have a 7-pin connector correct? Some people replace them with four pin so I just wanted to check.
