I found an owner's manual online for your 2007 Ford E-250 and it looks like the fuses for a trailer are in the following locations:
Passenger Compartment Fuse Panel -
15 - Trailer battery charge relay,Cluster, BSM
39 - Trailer tow electric brake, Center High-Mounted Stop Lamp (CHMSL), Brake lamps
Power Distribution Box (in the engine compartment) -
8 - Trailer battery charge relay
24 - Trailer tow running lamps and back-up lamp relays
26 - Trailer tow turn signals
C - Trailer back-up lamps relay
D - Trailer running lamps relay
E - Trailer battery charge relay
If all of these look good then let me know and I can help you troubleshoot further. I have also attached a link to a helpful article on troubleshooting wiring as well as our selection of replacement wiring for your E-250.

My fuses are good however when testing truck wires at the rear the only one with power is the running lights
