When crosswinds or passing trucks try to push your trailer around, this system steps in before you even realize it. The Tuson Trailer Sway Control System - Electronic - Up to 4 Axles uses built-in sensors to continuously monitor trailer motion. If sway begins, it pulses the brakes on one side of the trailer to bring everything back in line. It keeps working until the trailer is tracking straight again. Because it ties into your trailer’s electric brakes, it works automatically and doesn’t interfere with your brake controller or any built-in vehicle sway control.
If your setup doesn’t allow the use of a weight distribution hitch, this unit provides a dedicated way to fight sway. It’s the only sway control system designed specifically for trailers with electric brakes, including 5th wheels and goosenecks. Instead of adding heavy mechanical components at the hitch, it mounts directly on the trailer’s frame and handles sway electronically. It’s a great option when a mechanical sway bar isn’t possible or practical.
Once your trailer is stable for 30 minutes, the Tuson unit automatically enters sleep mode to conserve your auxiliary battery power. Tap the brake pedal or use your manual override and it wakes up instantly. That means you don’t have to worry about draining your trailer battery while parked or between stops—everything happens automatically.
This system isn’t just smart—it’s proven. In SAE J2664 trailer sway testing, even with aggressive oversteering, the trailer stayed within 7 degrees of the tow vehicle’s path. The sealed housing resists water and road grime, and the LED indicator light alerts you to normal operation, sleep mode, or any issues. Designed for electric brakes on trailers with 1 to 4 axles, the module measures 5-3/4" long x 3-1/2" wide x 2-1/4" tall and connects using a clearly labeled five-wire harness. It’s maintenance-free, weather-resistant, and built for long-term reliability.
Mount the LED display where you can see it in your rearview mirror, and you’ll always know when the system is active or if it needs attention. Once installed—typically a 3-5 hour job—the system works automatically every time you tow. Just hitch up and go, knowing your trailer’s sway control is already watching out for you.

I love this product . No more trailer sway. No more white knuckles when getting passed by 18 wheelers No more 50 mph with strong crosswinds.This is the best money I’ve ever spent in in some 50 years of trailer ownership.

Sounds like piece of mind when on the road, Robert. Where are you headed off to this summer with the camper?

Marvin, in this case I would use page 8 in the manual to make sure that it is wired correctly. Take a look at Figure 1 on page 9 to make sure the wiring on the left side of the trailer is correct. Check that only the PURPLE and WHITE wires are connected to the left side trailer brakes wired in parallel and not in series. It is very important that the trailer brake controller wire from the tow vehicle [blue wire] is ONLY connected to the BLUE wire on the TSC and NOT connected directly to the trailer brakes. I would then take a look at the troubleshoot able on page 10 - match the way the LED is behaving to the chart to see what is going on with it. If this does not work for you please let me know.

I wanted to reach out to you in regards to your review on the Tuscon braking system. You mentioned that it is taking a lot of sway before the system is working and I wanted to ask a few follow-up questions before I reach out to the manufacturer. Are you using a brake controller as well. If so what brand is it or was it from the factory? Does you GMC have an automatic leveling system? How many brakes do you have on the trailer or how many axles?

I reached out to the manufacturer about the experience that you had with the sway controller and it has led me to ask you a few questions. What are the highway or road conditions that you have been pulling your trailer? Tuson advises that the goal of the system is to only apply the brakes when the sway levels approach a medium level at higher speeds and not to activate on the smaller sways or at slower speeds. Are you experiencing sway at lower speeds or in town? Are you also using a sway control weight distribution system or only the Tuson system? You may consider adding on a weight distribution system for in town use. The Tuson system can work in tandem with it for when greater sway conditions apply.
Do you have a question about this Weight Distribution Hitch?
