Draw-Tite I-Command Trailer Brake Controller - 1 to 4 Axles - Proportional
part number: 5535

Brake controller activates trailer brakes in proportion to deceleration. LED screen shows settings and diagnostics. Features 3 boost levels. Automatically levels when mounted within 90-degrees in the vertical plane.

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
  • Automatically levels - internal sensor detects deceleration even if controller is not mounted level
  • Boost setting lets you adjust the aggressiveness with which the brakes are activated
    • Get full power output faster by pressing the plus button to increase activation speed
    • Achieve smoother braking by pressing the minus button to supply power gradually
  • Easy-to-read LED display shows controller activity
  • Short circuit protected
  • Built-in, slide-bar manual override
  • Quick and easy installation
    • Mounting bracket and hardware included
    • 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 4 axles (8 brake assemblies)
    • Designed for use with electric brakes only
  • Mounting angle: between -20 degrees and 70 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.


As long as the I-Command is properly mounted according to the included instructions, the controller will automatically level, sense the tow vehicle's deceleration, and adjust the trailer's braking accordingly. 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

The I-Command offers a boost feature that gives you more initial braking power for 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 14 percent or 28 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 GVWB114%
Equal to tow vehicle GVWB1 or B214% or 28%
Up to 25% more than tow vehicle GVWB1, B2, or B3* 28%
Up to 40% more than tow vehicle GVWB2 or B3* 28%


* 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 I-Command offers advanced safety features to prevent damage to various components of your towing setup. Integrated reverse battery protection shields the brake controller and your trailer's breakaway system from shorts.


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 lever is easily accessible. Pushing this lever engages the brakes on your trailer with full power.


LED Display

The I-Command has a digital LED display to keep you informed of your trailer's braking. The display shows the gain setting when the control is activated. It can also be used to check for connectivity with your trailer, to determine your boost setting, and to troubleshoot.


Automatic Leveling and Simple Installation

Because this controller operates with an internal inertia sensor, it must be mounted between -20 degrees and 70 degrees in the vertical plane. The I-Command 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.


The automatic leveling feature of the I-Command ensures that the brake controller continues to function even as you drive up steep hills or through the mountains. Mount the controller at a vertical angle that is between 0 degrees (level) and 70 degrees, and the controller with level itself automatically.


Installation of the I-Command requires that you either purchase a custom wiring adapter designed to plug into the controller or that you hardwire the controller directly into your vehicle. To hardwire the controller, you must remove the plug at the end of the integrated wiring harness.


Installation Accessories

For 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.


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

Tekonsha Plug-In Wiring Adapter for Electric Brake Controllers
part number: 3016

Install your electric brake controller quickly and easily with this custom wiring adapter. Simply plug one end of the adapter into your brake controller and then plug the other end into the built-in harness beneath your vehicle's dash.

Features:

  • Wiring adapter eases installation of your electric brake controller
  • Custom connector end plugs into the built-in port beneath the dash of your vehicle
  • Other end plugs into the back of your electric brake controller
    • Compatible time-delayed brake controllers: Draw-Tite Activator I (5100), Draw-Tite Activator II (5500), Draw-Tite Activator III (5520) and Tekonsha PowerTrac (39523)
    • Compatible proportional brake controllers: Tekonsha Prodigy (90185), Tekonsha P2 (90885), Tekonsha P3 (90195), Tekonsha Primus IQ (TK90160) and Tekonsha Voyager (39510)

Installation of Tekonsha Brake Controller Adapter

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 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.

Installation pix (3) as installed in 2020 Subaru Ascent... as you requested. Final assembly.. controller mounted and harness wrapped in white tape Bracket mounted in Subaru Ascent dash. Must drill hole in pretty leather but solid plastic base underneath is sufficient for solid mounting. Trial installation ....Harness wired into Subaru pigtail for testing and adjusting the brake controller. Initial wiring used wire nuts before final installation where I used "butt connectors" For info: 1. Dealer clueless on need for brake controller but offer a $600 tow (hitch) package that includes hitch (2" receiver) and 7 pin and 4 pin connectors. Those connectors are wired properly to provide alternator charging to trailer battery, brake lights, turn signals and trailer lights...just does not activate electric trailer brakes which they claim 2. Subaru hitch installation also includes brake controller pigtail (in plastic bag in glove box) 3. Subaru brake controller wiring plug under the dash, hidden behind a wiring bundle that was taped with pink tape. I understand the 2 high end Ascent models have this wiring connector included but dealer unaware. Google posts provide good, generic information on this wiring location but they recommend a larger brake controller which I felt was too big for he location I selected... thus I selected a smaller controller. If this was your profession, this kit from etrailer and the Subaru connector and pigtail would allow for installation in less than an hour. 776404

The wiring adapter I ordered was easy to install by following the included instructions! It is vehicle specific ,so I ordered one that fits my 2019 silverado 1500.It plugged into the 4 prong receptacle inside the block box under the dash to the left of the brake pedal against the fire wall.The other end plugged into the brake controller that I ordered(the wire adapter fits several different brands) I installed the Kenosha Primus IQ. Both items had concise, clear instructions with them.After finishing the install I plugged in the travel trailer and set the the brake controller by the instructions and it is working great!The install took me about 20 minutes. 735744

I purchased this for my 2014 Chevy Silverado long bed regular cab 4x4 work truck. It plugged in and worked fine and is great quality. The only disappointment was that it is too short in length. I would have liked to mount the controller right of the steering wheel, but it does not reach. It is only long enough to reach left of steering wheel. Not the end of the world. It works great. 121121

I tried finding the controller I wanted locally which ended up costing more time and money Then it should have. One of the places I stopped at was getting info from etrailer web page then adding his ridiculous mark up. When I got back to my office I ordered it from etrailer myself and bought exactly what I was trying to find locally but for much less money even with two day shipping. Beyond all that etrailer is the easiest place to shop and their tracking of my shipment couldn't have been any easier. From here on out if etrailer has what I'm looking for life will be just that much better. Thanks etrailer. 388783

Comments: A) It was a challenge to find the correct wiring for the red control wire for my 3rd generation Toyota 4Runner (1996). It would sure be nice to have a pigtail adapter that worked with that model, but I understand there would be a million different types of pigtails. I have suggestions for anyone else in this predicament with a 4Runner. B) The wiring diagram for the Draw-tite I-command Brake Control suggests this is always active -- directly wired to battery. Instead of plugging unplugging the pigtail, a rocker switch would be good. What is the idle current (amperage) draw (drain on battery)? How about current draw while actively braking? This would specify the type of rocker C) There is little description of the "gain" setting (vs the "boost"). How is this value dialed in for a particular load and boost setting? switch. 391425


Comments
So far very well. The boost needs to be changed for highway vs city driving B1 vs B. Perhaps this is a function of the Casita brakes, but brakes grab & lock up if I dont reduce the boost in city driving.

I put this controller in my Chevy truck and even though it is the cheapest one you can find, it works great. A few days later, the "top rated" one in my Suburban quit working, so now I have two of these controllers. They are adjustable for each of my trailers. You could spend six times as much for other controllers but I can't see that you get a better product than this one. 501979


Comments
A year later I still love both of these. I pulled heavy trailers over the Rockies this year without a second thought. With the same controller, I pull my flatbed empty and dont worry about the tires smoking. 5 stars.

The Tekonsha (item 3016) wiring harness allowed me to move my Tekonsha brake box controller from a Honda to a GM product with effortless ease. Instructions of where the harness connection was located in the new location (exact fit). The ability to have no splicing of wires and a clean, factory style, connection for a low price with a trusted manufacturer was a must. Always happy with Tekonsha products and ETrailer service. 513732

Ordered this for my 2008 Toyota Tundra to be able to pull a 25 foot travel trailer. This has been the easiest install. It takes literally 5-10 minutes to locate your quick connects and attach it to the dash. I mounted it as close to the middle console to help keep it away from my knee and legs. I used a black magic marker to blend the screws into the black frame. Once connected it automatically does everything else for you. I would recommend strongly on purchasing this trailer brake connector/quick connect along with using this etrailer. The shipping was extremely fast and communication was great prior to its arrival. I watched a YouTube video on my truck to make it even easier to install. 371551

I had purchased and used the Tekonsha Prodigy P2 Trailer Brake Controller on my 2000 Silverado with good results. When I got a new-to-me 2104 Silverado, I thought I could just buy a new cable and I was correct. It was delivered quickly and plugged in with no issues. The new truck's lower dash panel is more vertical than the older truck and I didn't want to drill holes in it for the mount, so I purchased heavy duty Velcro tape and cut it to fit. It has worked without issues. 446054

This has been the best and easiest purchase during my short journey of outfitting my 2008 Nissan Titan SE to haul a 27 ft camper. This has been the easiest install. If you're not mechanically inclined like myself no worries at all. It takes literally 5-10 mins to locate your quick connects and attach it to the dash. Once connected it automatically does everything else for you. You receive a set of directions just make sure you read them first and save yourself some money and do the install yourself. Once the camper was connected to the truck it was automatically detected. Can't get any easier than just connect and go. I would recommend strongly on purchasing this trailer brake connector/quick connect along with using this company. The shipping was extremely fast and communication was great prior to its arrival. 344916

2015 GMC Sierra 1500

As expected, service and pricing from etrailer was exceptional. 8th order in the past year and always satisfied with the customer service side of a transaction. The cable was "factory" from Tekonsha and was of very good quality, but it was about 8" too short for me to mount the brake controller on the right side of the steering column away from the door. I had an old wiring adapter from my previous truck and cut and spliced in a 12" section so that I could mount the controller where it was least in the way and easily accessible to me, the driver. And, if I need to move the controller in the future I now have plenty of slack. One more step, but not a big deal. All is good! 559160

THE CONTROLLER MOUNTED EASILY AND PERFORMED AS STATED. I'VE BEEN CONTENT WITH THE DRAW-TITE DELAY STYLE CONTROLLER I USED FOR 30 YEARS BUT THE PROPORTIONAL STYLE 5535 IS A MUCH BETTER CONCEPT. IT ACTS LIKE THE TOW VEHICLES BRAKES BY APPLYING MORE BRAKE THE HARDER THE BRAKES ARE APPLIED. I'VE ONLY USED IT ON ONE TRIP ON DRY ROADS WITH NO HARD STOPS SO IT MAY REQUIRE SOME TWEAKING THE MORE I USE IT. I TOW AN ENCLOSED 24 FOOT CAR TRAILER AND SET THE CONTROLLER MID RANGE ON BOTH SETTINGS AS MY STARTING POINT. 293519
