Unless you’re a born electrical wizard, wiring a trailer for towing can be a little intimidating. But if you have a RAM Truck with the available, integrated 4/7 pin trailer connector, the difficult part is already done.
As the name indicates, the RAM connector includes both four-pin flat and seven-pin round electrical receptacles, pre-wired into the vehicle’s electrical system and ready to go. You need only to plug in your trailer’s harness. These two popular connector types provide compatibility with the vast majority of trailers produced these days.
So which connector should your trailer use?
The four-pin connector is generally sufficient for most types of light trailers, for example utility haulers and pop-up tent campers. The four pins provide connections for the trailer’s tail, turn, and stop lamps, which are required by law, not to mention for safe and worry-free towing.
The seven-pin connector is called for with larger, heavier trailers including car carriers and large campers. The additional terminals support connections for features such as electric trailer brakes and reverse lamps.
The Ram’s 4/7 pin connector also provides clear, simplified circuit schematics embossed right on the cover, a handy feature. If you need additional info or assistance, be sure consult your local RAM dealer.
