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.

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.

Tekonsha Custom Wiring Adapter for Trailer Brake Controllers - Pigtail - GM
part number: 3016-S

Streamline the installation of your trailer brake controller with this custom adapter. Simply connect the wires of the harness to your brake controller and then plug the other end into the junction box beneath your vehicle's dash.

Features:

  • Pigtail wiring adapter eases installation of your electric trailer brake controller
  • Connector end plugs into the built-in port beneath the dash of your vehicle
  • Wire end connects to the wires on your brake controller with the included butt connectors
    • Compatible with time-delayed and proportional brake controllers from TrailerMate, Draw-Tite, and Tekonsha
  • Limited 1-year warranty


Installation of Tekonsha Brake Controller Adapter

To install your electric brake controller, you need to connect the wiring of the controller to your vehicle. Certain auto manufacturers offer pre-wired options, typically known as tow packages, wherein wiring is run for you from the dash to the trailer connector on the back of your vehicle. When this is done, a port is installed at your dash so that you can easily plug in a brake controller.


This adapter plugs into the 4-pin connector in your vehicle's junction box. The box is located underneath the dash, to the left of the steering column, just above the carpeting.


To hook this adapter up to your trailer brake controller, just connect the 4 wires of the harness - ground, power, brake switch, and brake power - to the corresponding wires on the brake controller. If your brake controller came with a plug built into its wiring harness, you will have to cut off the plug and connect to the wires themselves.

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.

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.

Have a 6 year old unit in my 2001 7.3. Kept Old Red and bought a new truck. Tired of factory brake failures and underperformance. Replaced with DirecLink. The low speed braking and holding brakes are available nowhere else. Awesome Tech Support.
