RV Braking System Tuson Sway Control Electric Brake Trailer Brakes TSC-1000

When a sway control hitch is not an option for your squirrelly trailer, use this instead. It ties into your trailer or camper's electric brakes to dampen sway the moment it starts. Works with all major OEM and aftermarket brake controllers.

Features:

• Automatically corrects sway so that you don't have to slow down or reach for your manual override
  • Uses sensors to continuously monitor your trailer for any type of sway, detecting it as soon as it begins
  • Returns stability and control quickly by feathering the brakes on one side of your trailer at a time
  • Remains active until your trailer is tracking straight again - ideal in those times when sway keeps building
• Won't interfere with your brake controller or with any sway control that's built into your vehicle
• Offers an alternative to sway control hitches
  • Great for vehicles with hitches that aren't rated for use with weight distribution
  • Only sway control solution for 5th wheels and gooseneck trailers
• Conserves your trailer's auxiliary battery life
  • Enters sleep mode after 30 minutes of inactivity
  • Wakes up when it gets a signal from your brake controller
• Automatically disables in rough off-road conditions to prevent unwanted braking
• Displays the module's status using an LED light display
  • Indicates normal operation, sleep mode, system issues, and more
• Resists water intrusion and road grime with weather-resistant housing
• Requires no maintenance
• Mounts on your trailer and splices into its wiring

Specs:

• Application: electric brakes on trailers with 1 to 4 axles
  • Not confirmed for use on ABS trailer brakes
• Module dimensions: 5-3/4" long x 3-1/2" wide x 2-1/4" tall
• LED cord length: 10'
• Wire configuration:
  • Purple: driver's-side electric brake output
  • Pink: passenger's-side electric brake output
  • White: trailer frame ground
  • Blue: brake controller from tow vehicle
  • Black: 12V DC from tow vehicle trailer harness

Quick Tip: If you typically have a lot of sway, take a look at your trailer's load. See if you can spread the weight out better to lower your tongue weight. A lot of times this will improve your ride, but if you still have sway, it'd be a good idea to invest in this device.

You might be used to applying the manual override on your brake controller to control sway. The Tuson sway control does this for you, automatically. It uses a built-in inertia sensor and a computer that continually monitors the angle of your trailer as it tracks behind your truck (the technical term is "yaw"). When your trailer starts to get off track, the module sends a pulsing signal to the brakes on the opposing side that the wind gust is coming from, which nudges your trailer back in line. After 30 minutes of smooth sailing, the unit enters sleep mode. But, just tap on your brakes or apply the manual override, and the unit will wake up and get back to work.

Electronic Sway Control that Works with Factory Tow Packages

When engineers at Ford, GM, Dodge, and Toyota took the Tuson sway control (TSC) out for a road test, they found that it worked in concert with their built-in brake controllers and sway control systems. In some cases, it even engaged before the vehicle's built-in functions. This shouldn't be a surprise because the TSC is based on the same technology used in automotive vehicle stability systems. So, if you need something that handles great on the trailer side because your truck already has sway control, this will create a super-stable setup.

Tested to Meet SAE Standards

The TSC also meets the SAE J2664 standard for trailer sway testing. Despite aggressive, exaggerated oversteering - more than what the SAE test called for - the trailer veered no more than 7 degrees off track from behind the tow vehicle. And if you own an F-150 or F-250, Ford has also verified that the TSC meets the towing requirements set by SAE J2807.

How To Install the Tuson Sway Control

1. Mount the module on your trailer frame's centerline, parallel to your axle(s)
2. Splice into your trailer's wiring
   1. Split your brake circuit into 2 separate ones
   2. Wire the left and right brakes to the module - requires 14-gauge wire extensions (sold separately)
   3. Connect to your trailer's 12-volt battery, breakaway switch, and trailer plug

This device installs permanently, and most people say it takes about 3-5 hours to do so. Tuson's installation manual is quite thorough, so please consult it - or a qualified electrician - when you need to.

The module should be installed on your trailer frame's centerline, parallel to your axles. This is usually a spot on the chassis, 5' to 10' directly behind your coupler. On smaller campers, an ideal spot may be right under the nose of your trailer. On larger 5th wheels, a flat mounting location may be found further back, as shown above.

To achieve independent left- and right-side braking, you're going to have to split your single brake circuit into 2 separate ones. To do this, you need to run 14-gauge wire extensions (sold separately) from the module to the respective sides of your trailer, where they'll be tied into to the wiring on the back of your brake assemblies. After that, connect the Tuson unit to your trailer's 12-volt auxiliary battery, breakaway switch, and trailer plug.

Quick Tip: Because this device relies on your auxiliary trailer battery to work properly, make sure it is fully charged before leaving on your next trip.

Finally, mount the LED light in a spot where it will be easily visible from your rear view mirror so you can tell right away when the system is working normally, it's in sleep mode, or if there's an issue that requires some troubleshooting.

To make sure the system is installed correctly, just plug in your wiring harness, power up your truck, and apply the manual override on your brake controller to wake up the TSC. The LED status light should be flickering green. If it isn't, check Tuson's installation manual for a step-by-step guide on how to troubleshoot.
