What is a Wiring Splitter?

A wiring splitter is an essential tool for towing trailers, as it allows you to connect the electrical system of your vehicle to the trailer. It acts as an adapter, converting the wiring from one type of connector to another. In this case, the wiring splitter converts a seven way plug to a four prong trailer connector.
