The main difference between 4-pin and 5-pin trailer connectors is that the 4-pin connector provides basic lighting functions such as tail lights, brake lights, and turn signals, whereas the 5-pin connector includes an additional pin to support an auxiliary function, typically for powering reverse lights or a trailer's electric brakes. The extra pin in the 5-pin connector makes it more suitable for trailers with more advanced lighting or braking needs.
