Keeping tabs on your trailer wiring can be tricky once you hit the road. The Ark Smart Trailer Connector makes it simple by using Bluetooth to monitor your 7-way connection in real time. You can check the status of your trailer lights and signals right from your phone, so you always know everything is working before and during a trip.

Wiring upgrades usually mean extra adapters or custom splicing, but this connector uses a direct USCAR plug for a clean, factory-style hookup. It’s built as a plug-and-lead setup, so you can connect your 7-blade trailer wiring without cutting or modifying anything.
Switching between vehicles or trailers can be a headache when wiring doesn’t match up. This adapter takes care of that with a universal 7-blade to 7-blade design that fits most setups. It keeps things consistent so you can tow multiple trailers without juggling different harnesses or cords.
Constant use and exposure to the elements can wear out ordinary connectors fast. The Ark Smart Trailer Connector is built tough with a durable plug and lead design, so it stands up to heavy towing seasons and rough conditions while keeping your electrical connection solid.

Hi everybody. Andy here with etrailer. Let's take a quick look at this Arc USCAR plug, seven-way smart trailer connector with Bluetooth. Now let's say you're packed up and you're ready to go and you plug your trailer in and nothing happens. No brake lights, no turn signals, they're all dead. Now maybe you're gonna be on your back in the gravel, underneath your truck, underneath your trailer, looking for the wire that's not working, wondering where the problem is.
Well that's where this ARC smart connector is going to end that guessing game. This is going to check every circuit the moment that you plug in and it's going to tell you what's wrong right from your phone. Now once the trailer is connected, this unit automatically begins a 22nd light test. That's gonna give you time to walk to the back of your trailer and confirm everything is working. Your brakes, your indicators, your reverse and taillights, and the nightlight LEDs are going to kick in when your vehicle's taillights, with your vehicle's taillights.
So if you're hooking up at dusk or in the campground, you're still going to have a clear view of the connector. So I'm trying to point out you got two LEDs here and two LEDs there. So that's a nice feature that's included with this as well. The plug itself is sealed to protect from dust and water and vibration, and it's going to mount easily with the included bracket that you see right here. So this is designed for vehicles with the factory seven way USCAR sockets.
The internal electronics are resin encapsulated for protection against moisture, vibration, and corrosion. And I do like that this cover is spring loaded, so (cover slapping) it's gonna be closed every time it's unplugged. You're not gonna have to worry about if that flap is actually closed or not. And we do have a a gasket in there that's going to keep everything sealed, which is great. Some measurements here looking at the overall width, about three and five 16 inches.
The overall length about almost five inches. The overall height, about three and a quarter inches. Instructions are also included to guide you through the installation and the operation. If you happen to have any other questions, don't hesitate to reach out. We wanna make sure that you're getting exactly what you need. Well, again, my name is Andy. Thank you for joining me.
