Where Are the Trailer Light Fuses Located On a 2014 Ford F-250

Question:

I cut my trailer wires when backing up, they were pinched and cut. Its a large toy hauler with back up lights, charging lead, right/left turn, trailer brakes. I repaired cut section but now have no turns, brake,s, brake lights. I do have running lights though. I’ve checked every single fuse on the in-cab fuse block. I’ve replaced the three relays in the engine bay fuse block. I bought the truck used, and no manual. Are there other fuses in the engine block that pertain to the trailer lights? Are there any other inline fuses that might trip before it gets to the aforementioned fuse blocks? Thanks in advances.

I have listed for you the trailer light fuse locations on a 2014 Ford F-250 below. The trailer light fuses will all be located in the engine bay fuse block, not the interior fuse block.

22 - 30A - Trailer Tow Electric Brake
26 - -30A - Trailer Tow Park Lamps
70 - 10A - Trailer Tow Backup Lamp
90 - 25A - Trailer Tow Battery Charge
100- 25A - Trailer Tow Turn Signals

If all of these fuses check out then you will want to test the pins inside vehicle side trailer connector. If you don't have power here then there is an issue with the vehicle's wiring and or computer. If you do have power here then you will need to start working your way back to see where the power stops.
