REESE® Towpower manufactures a full line of trailer electrical connectors to plug your trailer into your tow vehicle's electric system. For more than 70 years, we’ve supplied connectors to the towing industry, original equipment manufacturers, and even the military, so you can rest assured that our products are top-of-the-line when it comes to quality and safety. Our 4-way flat connectors are primarily for light duty trailers that require only limited lighting functions like right and left turn signals, stop and tail lights. We also manufacture 5-way flat connectors where a fifth wire hooks up to your backup lights. This allows you to deactivate the hydraulic surge brakes on your boat trailer when your vehicle is in reverse, so you can back up your trailer without locking the brakes. REESE® Towpower also manufactures a Professional Series 6-way pin connector and a 7-way blade connector for medium to heavy duty trailers – the preferred connector for the towing and RV industries. Our comprehensive line of connector products also includes mounting brackets; 4-way testers to check your vehicle’s lighting circuit; and a polarized connector to connect 12V accessories.
