If your trailer has surge brakes, there is no electrical connector to the trailer, other than a 4-pin for lights and signals. With surge brakes, the brakes are activated by a connection through the hitch, if I recall correctly. If your trailer has electrical brakes it will have what is called a 7-pin Bargeman plug which will mate with your truck electrical connection. The 7-pin plug has the wiring for the brake controller as well as lights.
