Trailers require electrical hook-ups that make towing safer for you and others on the road. In fact, while each state has its own laws and regulations governing everything from size limits to weight restrictions, the one thing they all have in common is that your trailer must be wired for tail lights, brake lights and turn signals. This is accomplished by connecting your trailer to your vehicle’s electric system. Unfortunately, not all trailer electrical wiring is compatible with the wires of your car, truck, van or SUV. Fortunately, REESE® Towpower manufactures a full line of trailer electrical components for everything you need to get your trailer lights up and running for safe towing. We manufacture T-Connectors, wiring converters, wiring connectors, adapters, brake controls and more to make towing safe for you and the drivers around you. Best of all, our products install quickly and easily with simple do-it-yourself instructions.

    Product Description
    REESE Towpower Professional Series combination connector offers the most convenient way to wire your vehicle to accommodate both a 7-Way connector and a 5-Flat connector. The 5-Flat connector is designed to handle the needs of most boat trailers where the surge brake systems need to be deactivated when backing up the trailer. Most 4-Flat connectors can also be plug into the 5-Flat connector giving greater flexibility to tow different trailers. The heavy duty stainless steel spring on the gasket sealed 7-Way connector cap, assists in keeping moisture and dust out of the electrical connections when not in use. Removing the snap on wire protector allows full access to the tin plate terminals for easy wiring. Look for other durable Professional Series REESE Towpower products to meet you electrical towing requirements.
