Hopkins' Multi-Tow Adapter attaches to an existing 4 flat to bring the lighting functions to both the 7 blade and 4 flat connectors, leaving electric brakes, auxiliary power, reverse lights, and ground as the only functions that need to be wired. The exclusive Multi-Tow design feature adds multiple towing options from one connector by providing sockets for towing both 7 blade and 4 flat trailers. Pre-wired adapters allow the consumer to create a custom Plug-In Simple wiring system appropriate for any towing situation.
