Tekonsha Brake Controller - TK90160

Proportional brake controller automatically levels when mounted within a 90-degree vertical range. Includes digital display, 3 boost levels, battery protection and continuous diagnostics. Easily transfer between different automobiles.


Features:

  • Brake controller activates trailer brakes in proportion to your vehicle's braking action
    • Automatically adjusts trailer's braking based on deceleration of tow vehicle
    • Activates immediately - no pausing like with time-delayed brake controllers
  • Automatic-leveling ability - internal sensor detects deceleration even if controller is not mounted flat
    • Position anywhere from 0 degrees (level) to 90 degrees in the vertical plane
  • 3 Boost levels let you adjust initial braking power and aggressiveness
  • Continuous diagnostic check alerts you to any potential problems
  • Integrated safeguards protect your vehicle and trailer
    • Minimizes drain on car battery when not in use
    • Prevents trailer brakes from overheating by reducing power output to them during prolonged stops
  • Easy-to-read LED display
  • Built-in, slide-bar manual override
  • Quick-disconnect feature lets you easily remove and store the control when not in use
    • Replacement wiring harness (sold separately) and replacement bracket (6927 - sold separately) required to move the controller from one vehicle to another
  • Plug-in, vehicle-specific brake-control adapter (sold separately) can be used for certain applications to reduce installation time


Specs:

  • Application: trailers with up to 3 axles (6 brake assemblies)
    • Designed for use with electric brakes only
  • Dimensions: 4-3/8" wide x 5" long x 2-1/2" tall
  • Mounting: between 0 degrees (level) and 90 degrees in the vertical plane
  • Limited lifetime warranty


Proportional Braking

With a proportional brake controller, you can get heavy-duty emergency braking, general braking or slow-to-an-idle braking for your trailer automatically. The intensity with which your trailer brakes are activated and the rate at which they are applied are dependent on the deceleration of your tow vehicle. This means that, unlike time-delay controllers - which send the same amount of preset power to your trailer brakes every time - proportional controllers are able to adapt to every braking situation differently. So, if you slam on the brakes in your truck, your trailer brakes will activate with that same extreme intensity. And if you merely slow down as you approach a red light, your trailer will gradually brake in the same manner. Just set the initial power level, select a boost setting, and you're good to go.


As long as the Primus IQ controller is properly mounted and is pointed in the direction of travel, it will sense - via an internal inertia sensor - how your tow vehicle brakes. This inertia-based sensor responds to the deceleration of your tow vehicle as you brake by signaling the controller to 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. No push-pull action - just smooth, proportional braking every time.


Power Boost for Heavy-Duty Towing

Aside from smoother, more efficient braking, Tekonsha's Primus IQ brake controller also offers a boost feature that gives you more initial braking power for those times when you're towing heavy loads. You can switch boost levels so that the power output to your trailer brakes automatically starts out at either 13 percent or 25 percent of the predetermined power setting.


So, if you boost the initial power so that your trailer brakes activate with 25 percent of the overall intensity at the start, the brakes will reach maximum braking faster. This is particularly beneficial if you are towing a heavy load because the intensity required to stop that load may be far greater than that needed to halt your vehicle. Therefore, sending out more initial power to the trailer brakes - and causing them to reach maximum braking faster - allows you to better control the trailer so that it doesn't push your tow vehicle before coming to a complete stop.


If your trailer weighs less than your tow vehicle, no boost is needed. But if you wish to set the boost so that your trailer leads the braking of your towing setup, you can select level B1. The following table gives an indication of when you might use the different boost levels and the power increases that they offer.


Approximate Gross Trailer WeightBoost LevelIncrease in Initial Power Output
Less than tow vehicle GVWB113%
Equal to tow vehicle GVWB1 or B213% or 25%
Up to 25% more than tow vehicle GVWB2 or B3*25%
Up to 40% more than tow vehicle GVWB3*25%

*Both B2 and B3 offer a 25-percent boost in initial power. But the braking curve for B3 is more aggressive than that of B2. This means that, even though you will start out with the same intensity when using these boost levels, you will get an overall more aggressive braking experience with the higher level. So if you use B3, you will reach maximum braking sooner than if you use B2.


Safety Features

The Primus IQ offers advanced safety features to prevent damage to various components of your towing setup. For example, when it is not in use, this brake controller will be in power-saving mode. In this setting, the power draw falls to minimize drain on your vehicle's battery.


When you stop at red lights, or any time that your truck and trailer are at a standstill with the brakes applied for more than 5 seconds, the Primus IQ's "hold" feature will activate. When this happens, the power output to your trailer's brakes will be reduced to just 25 percent of the preset power setting so that the brakes will not overheat.


If ever there is a time that you need to brake your trailer separately from your tow vehicle - when traveling down a steep incline, for example - the manual override is easily accessible. Pushing this slide bar engages the brakes on your trailer with full power. In addition, when you activate this override, the brake lights on your trailer will illuminate, properly warning those behind you of the braking action of your rig.


In addition to all of those safety features listed above, the Primus IQ offers diagnostics such as:

  • Open ground
  • Overload
  • Output short
  • Faulty mounting
  • Power loss
  • No trailer connection

Automatic Leveling and Simple Installation

The self-leveling feature of the Primus IQ ensures that the brake controller continues to function even as you drive up steep hills or through the mountains. Simply mount it in your cab at a vertical angle that is between 0 degrees (level) and 90 degrees, and the controller will level itself automatically.


Correct Primus mounting90-Degree Primus mounting

Note: The Primus IQ must be mounted on a level horizontal (side-to-side) plane and must be lined up with the direction of travel for the internal sensor to function properly.


Installation is a snap. After mounting the Primus IQ unit in your cab using the included bracket, hardwire one end of the included pigtail harness directly into your vehicle. The other end plugs into the brake controller. To transfer the Primus IQ to another vehicle or to remove it for storage, just unplug the unit and snap it out of the bracket.


Installation Accessories

For even easier installation, a vehicle-specific wiring adapter (sold separately) 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

The brake controller that I received worked very well. The plug and play brake controller adapter (3016) - not so well. After looking at all the reviews I decided to order the Primis IQ brake controller along with the wiring adapter (3016). I talked to Susan (customer service) and asked how long the wiring adapter was. I wanted to make sure I had enough wire to go from my fuse box to the controller. She told me the length was 35 inches. This was enough for me so I ordered it. Everything came to me in just a few days. Unfortunately I didn't measure the adapter wiring prior to installing the brake controller. When I started to wire the adapter to the controller I found out that the wire is only 27-28 inches long including the plugs. With a lot of stretching I was able to just get the adapter connected to my fuse box and my controller. If you purchase the adapter (3016) make sure you measure the distance from your fuse box to your controller prior to drilling holes in your dashboard or you may have to relocate your controller. I am pleased with instructions that are sent with the product. They are very well done and easy to understand. 568074

Can you tell us exactly what the issue was? According to the Tech Services folks at Tekonsha, theres nothing unique to your model year Escape that would prevent the successful installation of this brake controller.

Replaced an older brake controller with the TK90160. Installation was very straight forward and took less than a half hour. Hooked up the trailer, went to an empty parking lot, tested everything and adjusted the Boost feature. This unit is a superior brake controller. I do a lot of freeway driving as well as mountain roads (ie steep stuff) and I love the feeling of the trailer and the truck’s brakes working together. 563689

Great product. I followed the online video from ETRAILER.com for a 2017 Chevy Colorado with excellent results. My truck is a 2018 Colorado which has the same wiring (no plug n play like the Silverado). Made sure the color coding of the 4 wires were connected properly as described in the video. All you have to do is pay attention to his instructions. Now I can safely pull my 16 foot trailer loaded with tractor. Thanks, Hugh 554796

I have not connected the device as of yet. However delivery and price were on point. I have a 2005 Toyota Tundra that does not have a factory tow package and I need to know exactly were to connect into the brake switch. The truck does have the 4 prong connection so I can use the ETBC7 kit that will definately save several wire connections. The kit came with a great diagram. It is just the exact location to connect the one wire on my specific vehicle. 424889

I have not hauled with this brake controller yet, but given the ease of installation and simplicity of controls i'm not sure how i could be disappointed. For my hauling needs (Only a 6k gvwr 2 axle trailer) this is perfect and a reasonable price for a proportional controller. Better yet was etrailer.com not setting false expectations on arrival. There are "two-day guaranteed" shippers that often fail to meet, while etrailer estimated a realistic travel time and actually beat it by a lot! 554652

  • Is Using a Brake Controller Necessary for Towing a Trailer
  • If the trailer is equipped with electric brakes and you want them to actuate, you'll need a brake controller. A brake controller is a fairly small investment that will go a long way to keep you safer when towing. There are two types of controllers, the older time-delayed variety and the newer proportional type. I'd recommend going with a proportional controller like the Tekonsha Primus, part # TK90160.

  • Installing Brake Controller in 1995 Ford F150 with Aftermarket 4-Way Trailer Connector
  • Since your truck is apparently not equipped with the factory 4-way connector, the brake controller output wire has not been run to the rear of the truck. You will need the 4 to 7-way trailer connector adapter, part # 37185 and the brake controller wiring adapter, part # 3035-P. The adapter would plug into the connector under the dash, and the other end would plug into a Tekonsha Brake controller, or if you have another brand you'd just cut off the black connector and wire it to the controller....

The flipper switch on the side of the controller does control the aggressiveness of the brake application. With the lever flipped back away from the front of the controller the braking will be delayed, straight down will be normal, and towards the front is aggressive.

  • Troubleshooting Tekonsha Primus IQ Trailer Brake Controller That Shows Connected But Doesnt Work
  • Testing the brake controller is fairly easy. Sever the blue brake output wire near the brake controller leaving enough room to reconnect it and then apply the manual slide. Using a circuit tester like part # PTW2993, you should get output to the controller side of the wire you severed. If the manual slide activates the trailer brake output wire properly, try the brake pedal. If the brake pedal activates the brake output properly also then the problem is farther back either in the vehicle...
