A 4-pin to 7-pin trailer adapter allows a vehicle with a 4-pin connector to connect to a trailer with a 7-pin connector. It typically converts the basic lighting functions (tail lights, brake lights, and turn signals) from the 4-pin connector while the additional pins on the 7-pin connector can be used for auxiliary functions like electric brakes, reverse lights, and a 12V power supply.
