Proportional Braking

What is proportional Braking

The Tuson DirecLink is unique in that it connects directly to your vehicle's computer network, constantly reading data from your vehicle to give you proportional braking. Proportional braking means that your trailer brakes mimic your tow vehicle's brakes. Using multiple data parameters, this brake controller will analyze your tow vehicle's braking and momentum. It will then send out enough power to your trailer brakes so that they are activated with an intensity that matches. The result is uniform braking across your towing setup, saving wear and tear on the tires and brakes of your trailer. No push-pull action - just smooth, proportional braking every time.


DirecLink Operation

With the main unit mounted out of sight, the remote puts control of your trailer's brakes right in your hand. In addition to offering fast and easy power adjustment and a manual override, it keeps your cab clutter-free and your towing experience simple.


Tuson DirecLink remote

Using the up and down buttons on the handy remote, select the brake scale for your trailer. This will set the amount of power the brake controller sends to your trailer to bring it to a stop; how much you'll need will depend on the weight of your trailer. You'll want to set the brake scale as high as you can without locking up the brakes. There is no need to adjust this setting unless you are going from an empty trailer to a fully loaded trailer or vice versa.


Tuson DirecLink remote manual override

The remote also puts the manual override right in your hand, great for stopping sway or controlling your trailer's momentum in emergencies. To engage the manual override, just press the trigger. This will activate the trailer's brakes and brake lights without you having to apply the brakes on your tow vehicle, perfect for limiting trailer movement while you're cruising.


Tuson DirecLink review

Low-Speed Brake Adjustment

The DirecLink has a unique feature to make your braking smoother: low-speed braking adjustment. When you're cruising on the highway, you need a different amount of braking power to slow your trailer than when you're driving slowly through town. The low-speed braking adjustment on this controller adds the option of a secondary setting to the brake scale. Use the sub-menu on the remote to set the low-speed setting. The DirecLink will use this level of braking scale whenever you're towing below 30 mph, so you have smooth, safe, and comfortable braking at any speed.


Customizable Settings

In addition to the essentials of towing, the Tuson DirecLink has an extensive menu of extra features for configuring the controller to suit your needs and preferences.


Trailer Size

At the standard brake scale setting, the DirecLink offers 20 levels of braking. This is designed for trailers less than 10,000 lbs. For trailers more than 10,000 lbs, the DirecLink has an additional 20 levels to choose from, making 40 total, so you have more flexibility to find just the right brake scale for your larger trailer.


Adjust Braking Power for Long Stops

When you're waiting at a red light or stuck in bumper-to-bumper traffic, you don't need your trailer brakes on at full power. The longer you sit there, the more likely they are to overheat. To keep your trailer's brakes from wearing out prematurely, you can set a different braking level for when your vehicle is stopped. You can set it between 5% and 30% of the full brake scale, and that will keep your vehicle and trailer in place on a steep grade or a slippery boat ramp without overdoing it.


Maximum Brake Limit

The maximum brake limit feature lets you fine-tune your braking so you can find the perfect blend of safe and comfortable braking. It allows you to set a high braking level for your manual override, especially important for large and heavy-duty trailers, while moderating your normal-use braking. So if your brakes lock up at 75% of your set brake scale, you can dial the maximum brake limit back to 70%, while still having 100% braking power available for an emergency. You can tow with peace of mind without sacrificing a comfortable ride.


Tuson DirecLink brake controller

Real-Time Diagnostics

Because the DirecLink is direcly connected to your vehicle's computer, it is able to access its data and offer a large range of diagnostics, including:


  • Trailer connection
  • Tow vehicle battery voltage
  • OBD-II network connection integrity
  • Brake controller ground and power connection
  • Brake switch voltage
  • Blue wire voltage and current output
  • Blue wire short
  • Engine RPM
  • Transmission temperature (only available for Ford and GM vehicles using VPW/PWM network protocols)

Simple Installation

With a vehicle-specfic harness, the DirecLink offers an easy, plug-and-play installation. If no custom harness is available for your vehicle, use the included wiring harness to hardwire directly into your vehicle's wiring, and then plug into the controller. The other harness on the DirecLink plugs right into the OBD-II connection port on your vehicle. Once you plug this harness in, the DirecLink will automatically configure to your vehicle's system.


The DirecLink can be mounted at any orientation, so you can install it wherever's convenient for you. Use the included cable ties and the corner holes to secure the main unit to a stable location where it won't shift or move. The remote comes with a flush dash mount and a swivel dash mount with adhesive so you can put it on your dash with no drilling required.


Installation Accessories

See etrailer.com's exclusive 7-way upgrade kit for brake controller installation (ETBC7 - sold separately) if you don't already have a 7-way plug at the back of your vehicle.

Complicated to install - used mechanics shop for install - had the wrong OBD interface cable initially, delayed / complicated further.

Unit functions well. Happy with it overall and would recommend it.

Manufacturer and e-trailer were readily available to provide extra support.

Great controller and easy to use. The hand held feature makes this tremendously easier to utilize especially through the mountain passes along with being less obtrusive when not in use as you can just disconnect the controller and put it in your storage compartment.

Everything arrived before due date and was well packaging. You all rock, and also, the items are good. . Best place to order all your trailer and truck accessories.

The brake controler itself works great... I had only 1 problem... I was told to wire it direct to the batteries and not to try to connect to the ignition switch... I found later when not in use and my truck parked it was draining my batteries.... So I put a switch in it.. Other than that its a good system...

See what our Experts say about this Tuson RV Brakes Trailer Brake Controller

  • Difference Between Tuson Heavy Duty Truck Module Kits for DirecLink Brake Controller
    The difference between the two is the 9-pin Deutsch connector they are compatible with; one is for green 9-pin Deutsch connectors (which have a slightly larger pin size) and the other is for the standard 9-pin Deutsch connector. So you wouldn't be able to use either on your truck, you would need to look at your 2007 Volvo 670 VN to see what color the 9-pin connector is; this is typically found under the dash. That will allow you to determine the right connector: - Tuson Heavy Duty Truck...

  • Installation Process For A Trailer Brake Controller In A 2022 Toyota Highlander
    Before you can install a trailer brake controller in your 2022 Toyota Highlander you'll first need to make sure that you have a 4-pole wire harness for your lights installed and then a 7-way wire harness to get your brake function. If you don't already have a 4-pole installed then you'll want the Tekonsha # TK74FR if you have a factory tow package or the Curt # C59236 if you don't. From there you can install a 7-way # ETBC7. The # ETBC7 will have a 4-pole connector to connect to the 4-pole...

    I spoke to Tuson and the DirecLink Base Model Trailer Brake Controller # 335DL-100 can have some issues with some of the Dodge trucks up to 2007. They mentioned that it is actually an issue with the truck's systems, but again, not all of them. Unfortunately, the only way to tell if there is an issue is to try the # 335DL-100 and see if it happens. If it doesn't, you are good to go. However, if it does happen, you just need to let us know and we can set up a return.

    Hello Kevin. In regards to the Tuson DirecLink Base Model Trailer Brake Controller # 335DL-100, the black 12v wire does need to be connected to the battery for constant 12v power. They also recommend that the white wire be connected to the negative battery terminal for proper ground.

  • Can Tuson DirecLink be Used with Semi Trucks
    Since even semi trucks like what you have use OBDII connectors the Tuson DirecLink Base Model Trailer Brake Controller # 335DL-100 that you referenced can be used. The module of this is what interprets the brake signal from your tow vehicle and decides how much brake pressure to apply. As long as your current adapter setup has a brake output circuit that makes it's way to the trailer brakes that wouldn't be an issue either.
