    • Get full power output faster by moving switch forward to increase activation speed
    • Achieve smoother braking by moving switch in opposite direction to supply power gradually
  • Digital display is easy to read
  • Built-in, slide-bar manual override
  • Quick and easy installation
    • No need to mount level like proportional brake controllers
    • Mounting bracket, wiring harness and hardware included

Time-Delayed Braking

The Activator III applies your trailer's brakes when the brake pedal in your tow vehicle is engaged. Every time you apply the brakes in your vehicle, a signal is sent - via the brake switch - to the Activator. The controller then sends power out to your trailer brakes to activate them with an intensity set by you, at a rate determined by you. Both the amount of braking power (output) and rate of application (sync) can be adjusted to suit your preference, the road conditions, type of trailer and size of the load. To determine which levels are best for your application, you must test out your towing setup and choose what feels best.

A time-delay controller is so named because there is a delay between the time that you initially apply the brakes in your tow vehicle and the time that the controller reaches maximum power output. Unlike a proportional brake controller, which activates your trailer's brakes based on the deceleration of your tow vehicle, the Activator sends power out in the same way, with the same gradual delay, no matter the braking situation. Although this delay always exists, it can be adjusted by changing the sync setting.

Sync Settings

To adjust the aggressiveness of your trailer's braking action, use the slide control on the side of the Activator III to change the sync setting. If you want to reach maximum power output faster, move the switch forward. To get smoother braking action, move the switch backward, thus supplying power to the trailer brakes more gradually. You can alter the sync setting to suit your driving preferences or to improve handling based on changing road conditions or varied trailer loads.

Quick, Simple Installation

Because inertia plays no role in the functioning of this controller, you do not have to mount the unit at any particular angle. As a result, mounting options are limitless, so long as you can still easily access the controller. After mounting the unit, hardwire one end of the included pigtail harness directly into your vehicle. The other end plugs into the brake controller.

Installation Accessories

For even easier installation, a vehicle-specific wiring adapter is available for most newer trucks and SUVs. One end of the custom adapter plugs into your vehicle, and the other end plugs into the controller - no hardwiring required.

Note: If a custom brake-control wiring adapter is not available for your vehicle, one of the following will be required:

20-Amp circuit breaker (9506P - sold separately) for 2- to 4-brake applications

30-Amp circuit breaker (38630 - sold separately) for 6- to 8-brake applications

See also's exclusive 7- and 4-way brake-control installation kit (ETBC7 - sold separately) if you don't already have a 7-way plug at the back of your vehicle.

Installation of Tekonsha Brake Controller Adapter

This adapter plugs into the 5-pin connector on your vehicle's built-in brake control wiring harness. The harness is located underneath the dash, to the left of the steering column, taped to another harness near the emergency brake pedal.

To install your electric brake controller you need to connect the wiring of the controller to your vehicle. Certain manufacturers offer pre-wired options, typically known as tow packages, wherein these wires are run for you from the dash to the trailer connector on the back of your vehicle. Often, a brake controller wiring harness is included with your tow package. This harness plugs into a port beneath your dash and connects to the four wires of the brake controller. If, however, you have a brake controller with a plug in place of the four loose wires, you can use the Tekonsha adapter.

This adapter requires no hardwiring. It is designed to plug directly into your electric brake controller for the simplest installation possible. Because there are no wires to connect, installation is not permanent. You can unplug and remove your brake controller at any time and securely stow it away.

Video Transcript for Trailer Brake Controller Installation - 2010 Toyota Tundra

Today on this 2010 Toyota Tundra we are going to install part number 90885-3040P. First thing we will do is show you where the port is on the vehicle, this has a factory tow package. It is going to be underneath the dash on the left hand side. First thing we are going to do is plug the adapter cord into the factory port right here. Next, we are going to take our ground wire and ground it to the piece of sheet metal right here next to this fastener. :31

Then we will take our cord and route it behind the dash and over to our location where we are going to install our brake controller. We will let that sit for now. There is not much room to install the brake controller. This is because we can not do anything in this area here because that is where the air bag is. So what we are going to do is mount it offset. We will mount it to the flat spot here on the plastic. Make sure there is nothing in the way. We will have the bracket offset this way. 1:08

Now when we install this we are going to use just one side of the bracket. We are going to put our screw on this side and this side to help hold it up. Now that a second to set your brake controller up, make sure it is straight and aligned with the vehicle. Then we will use the other screw to help set it in place. Now we will plug the adapter cord into the back of the brake controller and then install the brake controller on the bracket. Snug up the screws. 1:56

Now this is tight quarters, what you can do is use a bit and a 1/4 inch wrench on the end to help you get a little extra torque in. With that, our brake controller is already installed. There you have it for part number 90885-3040P.

  • Troubleshooting a Draw-Tite III Brake Controller OL Code on a Trailer with New Brake Assemblies
  • The OL code you are seeing indicates that you have a short on the brake output circuit. This can be a lot of things such as corrosion on the trailer plug to exposed wire somewhere on the circuit. Since you just changed the brake assemblies I would start by checking the connections you made to wire in the brake assemblies. There may be a loose wire thats not making good contact or shorting out. Or, there could be corrosion on the connector as that is usually the culprit in these situations.
