Got a slide-in truck camper and need to tow a trailer behind it? This Oyviny 7-way Y splitter makes it super easy. It's a simple plug-and-play adapter: one 7-way female plug connects to your truck's socket, and the two 7-way male plugs let you hook up both your camper and trailer lights at the same time. No cutting or splicing wires – just connect and go. The adapter is about 20.5 inches long with a black nylon loom protecting the wires, and the male plugs have spring-loaded dust covers to keep out dirt and moisture. It's built with sturdy ABS plastic housing, brass terminals, and thick copper wiring (1-10 AWG, 2-12 AWG, 4-16 AWG) for reliable conductivity. Perfect for RVers, haulers, or anyone towing double trailers. It keeps your lighting system legal and safe, so brake lights, turn signals, and running lights work on both units. Installation takes seconds, and it stores easily when not in use. If you're setting up a combo rig for camping, work, or play, this splitter is a must-have accessory that saves you a headache. Durable, functional, and straightforward – exactly what you need for hassle-free towing.
