Features to know about

One Connector for Every Trailer: Dual 7-Way and 4-Flat Plug

Switching between trailers with different wiring types can be a hassle. The TowSmart ProClass trailer connector solves that by giving you both a 7-way blade and a 4-way flat socket in one compact plug. You can tow campers, utility trailers, or boat trailers without swapping connectors or messing with adapters.

Clean Look and Secure Mount: Oval-Mount Design

Loose or hanging connectors can get damaged fast. This oval-mount socket installs neatly on your hitch or bumper for a tidy, secure setup. The design keeps the plug easy to reach while protecting the wiring from strain and road debris.

Built for Vehicle Ends: Ready for Hitch Wiring

This connector is designed for the vehicle end of your trailer wiring system. It ties into your existing hitch wiring to give you reliable power for trailer lights, brakes, and accessories. The solid construction holds tight connections so your signals stay consistent trip after trip.

Universal Fit That Keeps You Rolling

No need to worry about compatibility headaches. With its universal fit and dual-style connection, this TowSmart ProClass plug works across a wide range of towing setups. It’s a straightforward, durable way to make sure every trailer you hook up has the lighting and power it needs.

Video Transcript for Review of TowSmart Custom Fit Vehicle Wiring - ProClass Connector Oval Mount 7 Way 4 Way - TS49RR

Hi, everybody, Andy here with etrailer.com. Let's take a real quick look at this TowSmart ProClass trailer connector, oval mount seven-way and four-way flat. Now, this socket is going to fit your standard oval factory cutouts. And as you can see here, it's going to give you both a seven-way and a four four-way flat trailer connector. And this is gonna be ideal for tow vehicles that need to switch between trailer types. And this is a very durable socket.

It's sealed, so it's gonna help protect against and block road grime. And if you notice here, both of our covers here are spring-loaded, so they're going to do a good job of keeping those sockets clean when they're not in use. And I just wanted to put a ruler to this to give you some overall measurements. So, looking at the overall length, we're sitting at about five inches. And then, looking at the overall width, including the socket, about 3.5 inches, not including the socket, about an inch.

And then the height, about 2.5 inches or so, maybe slightly under if you wanna get technical about it. But if you happen to have any other further questions that I did not cover with you today, don't hesitate to reach back out to us. We do have a variety of products from TowSmart, so maybe this isn't exactly the one that you're looking for. Take a look at the other options that we have, and like I said, if you give us a call, we'll be sure that you're getting exactly what you want and need. Well, I think that's gonna wrap up our quick look today.

I do hope that it was helpful for you. Again, my name is Andy. Thank you for joining me.

This item does not work with my 2024 GMC 3500 HD because when fully inserted, the collar bottoms out before the pins make contact.

  • Recommended 7-Way and 4-Way Connector for a 2024 GMC Sierra 3500 that Can Be Used At the Same Time
    Hey Scott. To add a 7-way and 4-way connector to your 2024 GMC Sierra 3500 that can be used at the same time, I recommend the TowSmart ProClass Trailer Connector item # TS49RR. It's going to replace the factory one and mount in the same position on your bumper. It is going to plug directly into what's called a USCAR connector. This is the standard wiring connector available on American cars with factory tow wiring. The covers open the opposite direction on the TowSmart ProClass Trailer...

  • Can the 7-Way and 4-Way Be Used at the Same Time on the ProClass Trailer Connector TS49RR?
    They sure can Craig! The covers open the opposite direction on the TowSmart ProClass Trailer Connector item # TS49RR, allowing you to connect both a 7-way and a 4-way wiring harness. Please note that you will still be limited amperage wise by the towing circuit you connect the ProClass Trailer Connector item # TS49RR to. If you are just running low draw LED accessories like an LED tailgate light bar or hitch step light with the 4-way, while your main trailer is plugged into the 7-way,...
