Plug-In Simple Adapters take the guesswork out of vehicle-to-trailer wiring. Pre-wired adapters allow the consumer to create a custom Plug-In Simple wiring system appropriate for any towing situation. Multi-Tow Adapters provide two towing options from one vehicle-end connector creating a true customized Plug-In Simple! wiring system. Hoppy Multi-Tow's provide either a 7 RV and 4-wire flat connectiion or a 6-way round and 4-wire flat connection. Hoppy now offers a complete line of L.E.D. vehicle-to-trailer adapters. The new patent-pending L.E.D series incorporates built-in trouble shooting. If the trailer lights are not functioning correctly, you can isolate the problem by simply looking at the adapter. If the lights on the adapter are functioning, it's a trailer-side problem. If the lights are not functioning, the problem is with the vehicle.
