When a trailer’s 7-way connector gets worn out or corroded, there’s no need to replace the whole harness. This Roadmaster plug gives you just the connector end you need to get back on the road. It’s the simple way to repair or refresh your wiring without starting from scratch.
The 7-blade design is what most trailers use for running lights, brake lights, turn signals, and electric brake control. This plug connects at the vehicle side to keep everything working together safely and reliably when towing.
You don’t have to worry about brand or model compatibility here. The universal fit makes it easy to replace an existing 7-way plug on just about any setup that uses standard trailer hitch wiring.
Roadmaster builds this plug to handle constant connect-and-disconnect cycles and outdoor exposure. It’s made to hold a secure connection trip after trip, so your lighting and brakes keep working every time you hook up.

Hi, everybody, Andy here with etrailer.com. Let's take a quick look at this replacement Roadmaster seven-way round plug. Now this plug is something that you'd pick up if your existing trailer wiring plug is worn out, damaged, or just giving you headaches. Over time, these plugs can take a beating. They get exposed to weather, road grime, and constant connecting and disconnecting. If the contact start corroding or the casing cracks, you could end up with flickering trailer lights, poor braking signals, or even a total loss of connection while towing, which is not fun or safe.
So by swapping in this replacement, you're basically restoring a clean, solid electrical connection between your vehicle and trailer. This is built to fit directly into the Roadmaster wiring setup that you already have, so you're not gonna have to worry about compatibility. Plus, having a fresh, reliable plug means that your trailer lights, brakes, and turn signals are all gonna work the way that they should, giving you peace of mind when you're going down the road. So this should be a pretty simple installation. You're gonna get exactly what you see here.
