So I am new and this is my first post, however i have been reading posts on titan talk for 6 months. I have searched this forum for two hours today before i decided to register. My problem is I bought a used 09 Titan SE w/o big tow. I have since added a receiver hitch in order to have the ability to pull a trailer. I added a Prodigy P2 last week. When I hooked up to the trailer I needed to pull I do not have trailer brakes. The controller gives me the "n.c" for "no connection". I have power to the controller and also have all running, brake and turn lights on the trailer. I believe I have all relays since I have lights. Any suggestions would be greatly appreciated.
