It sounds like you have a short in your system if I am understanding you correctly. I recommend starting at your trailer connector and checking the wiring behind it for function using a circuit tester like # PTW2993. I've attached an article to help with the pin/function locations which will be consistent even if the color wire is not.

If you have the wiring functions located where they are working, you can also determine which wires are not working and trace them back to where they are working. If you find the issue is indeed at the circuit but your tail light functions are working on your truck, then you can use the Pollak 7-Pole, RV-Style Trailer Connector Socket w/ Wiring Harness and Mounting Bracket # PK11898 to splice in the wiring functions for a new trailer connection.
