Hey there, RV and trailer owners! Got a truck but missing the right wiring hookup for your trailer lights? This universal 7-way RV wiring harness is exactly what you need. It's a brand new, unused harness that comes in original packaging (might not be fancy retail boxing, but it's sealed and ready). Made by CM, it's designed for the truck side, meaning it connects from your vehicle to the trailer's 7-pin socket. The harness has bare wire ends, so you can customize the connection to your truck's wiring setup. It's all black, made with durable plastic connectors, and rated for standard 12-volt systems. Since it's universal fitment, it should work with most trucks and trailers that use a 7-pin setup. Just a heads-up: there's a California Prop 65 warning (some components might contain chemicals). Installation is pretty straightforward if you're handy with automotive wiring. Width is about 2 inches. Perfect for towing campers, utility trailers, or horse trailers. Get your lights, brakes, and turn signals working safely on the road!
