Since the fuses and relays of your 2014 Ford F-150 are in place and not blown but you are not getting power to the passenger turn signal or brake light on the trailer connector there are a few possible causes.

First using a circuit tester like # PTW2993 test the wires going into the back of the trailer connector to see if the wire came loose from the inside of the connector.

If no power is there then trace the wire back towards the front of the vehicle checking for power every few feet, and also look for any damage that could cause power to stop.

If you cannot find any damage or power then test both sides of the fuse with the circuit tester and make sure there is power on both sides of the fuse. If there is not power on either side of the fuse then there is an issue with the wiring between the fuse box and the battery that will need to be identified and corrected.
