If you have tested the pin for the right turn signal at the trailer connector, have you used a circuit tester to probe the wire that feeds the connector? If you get no signal there, you most likely have a blown fuse.

Typically, the fuses that protect the towing circuits are located in a fuse box in the engine compartment. Your owners manual should have more specific information about the fuse location.
