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

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

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.

We do not have any instructions for this item either, but I do a help article that explains the details of how to install this item. This is a hard wire application for Draw-Tite or Tekonsha branded brake controllers, this is where the black plug end will install. The loose wires will then be connected to the corresponding functions on the vehicle: Blue: trailer brakes White: vehicle battery negative terminal Black: vehicle battery positive terminal Red: cold side of stoplight switch

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

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.

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

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

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

Probably the easiest thing that I have ever done in the automotive world. The online guide was perfect! Easy to read, follow, and explained very well. When I contacted customer service about what I needed, not only did they explain things to me, but the representative sent (via email) pictures, prices, and part no. for the items I needed. It took the hunting and surfing out of it. I figured with customer svc. like this, why try to search for something a dollar cheaper. I will probably always go here from now on. 855246

  • Does a Brake Controller Have to be Hardwired in 1991 Chevy C/K Truck
  • Yes, a brake controller will need to be hardwired into a 1991 Chevy C/K Series truck, though the installation is not something overly difficult. To install the brake controller I recommend for your truck, the Draw-Tite I-Command Trailer Brake Controller # 5535 you will need the Brake Control Plug-In Harness # 20127, which plugs into the I-Command and has four wires, a black power wire, white ground wire, blue brake wire and red stop light switch wire.

  • Flashing E.r Error Code on Draw-Tite I-Command Trailer Brake Controller
  • The "E.r" error code you have on the Draw-Tite I-Command Trailer Brake Controller part # 5535 means it is inoperative so it must be replaced as they are not serviceable. This is outlined in the troubleshooting chart section of the owner's manual. I am not really sure of the correlation between the brake controller going bad and a brake line failing but nonetheless it will need to be replaced. I recommend the Tekonsha Voyager Trailer Brake Controller part # 39510 which is similarly priced

  • Installing Draw-Tite I-Command Brake Controller on 2012 GMC Sierra
  • To install the Draw-Tite I-Command Trailer Brake Controller # 5535 on your 2012 GMC Sierra, you will just need to add the Pigtail Harness # 20127. If your Sierra is equipped with a fully-functional 7-Way connector, there is not a plug-in-play style port present under the dash, but all the needed wires are already run. What this means is that the installation will not quite be a plug-and-play process, but all you will need to do is connect the brake controller wiring to the vehicle wiring

  • Brake Controller Recommendation for 1999 Ford F-150
  • The brake controller we recommend is the Tekonsha iCommand # 5535. This controller is a fully proportional brake controller that applies the brakes of your trailer in the exact same speed and strength as your tow vehicle brakes. This style controller is much safer and easier on braking components than a time-delayed controller. For your truck you can use the wiring adapter # 3035-P, for a direct plug in application.

  • Do All Proportional Brake Controllers Have to Mount the Same Way
  • Proportional brake controller like the iCommand part # 5535 that you referenced can not be mounted on their side since they use an internal inertia sensor to decide how hard to apply your trailer brakes.

  • Draw-Tite I-Command Trailer Brake Controller 0.9 Error Code
  • The fact that your old controller and the new one, # 5535, both had errors and/or were acting strangely indicates that the issue could be with either the controller wiring harness or the vehicle's wiring. What you can do is splice in a jumper ground wire to the brake controller white wire and attach the other end to a bare metal surface. Ideally you would ground it to the negative battery terminal but for this test you can attach it to a metal surface in the cab somewhere under the dash.

  • Troubleshooting Hopkins Reliance Brake Controller that Stopped Working with Brake Pedal
  • The Hopkins Reliance was a very problematic brake controller when we carried it. We found it had many bugs that required frequent resets and it also was prone to internal problems that took it out of commission. I'd suspect highly that yours is bad based on our experiences and everything you've tested so far. So I would recommend you replace it with an iCommand part # 5535 and you'll have a much more reliable controller that will work better as well.

  • Electric Trailer Brake Controller Recommendation for a 2009 Volkswagen Touareg TDI
  • I recommend the Tekonsha P2, # 90885. It is one of our highest rated and most popular brake controller models. If your Touareg has a factory tow package, then you will just need to connect the wires from the brake controller to the tow package wires under the dash. The tow package wiring may be located behind the lower appearance panel beneath the dash and to the right of the emergency brake pedal. It may be on the left, wrapped in grey foam. I have included a link to an FAQ article

  • Do the Tow Ready and Tekonsha Brake Controller Harnesses use the Same Guage Wire
  • The Tow-Ready part, part # 20127, and the Tekonsha part, part # 7894, use the same size wires. The blue and black wires are 12 gauge and the red and white are 16 gauge. They are the same part other than wire length.

  • To install the Tekonsha PowerTrac Brake Controller # 39523 in your 2006 Ford Escape, the red wire on your brake controller harness # 20127 needs to be connected to the stoplight switch under the dash in your vehicle. There should be a wire for the stoplight switch on the back of the brake pedal. You will want to use a circuit tester, like # 40376, to find the wire that has signal only when the brake pedal is depressed. Testing the wires is the best way to be sure which wire is the one

  • Does the Tow Package Wiring on a 2008 Chevy Colorado Match a Brake Controller Color for Color
  • On the 2008 Chevy Colorado with a factory tow package, the wiring for a brake controller is located under the dash, to the left of the brake pedal. The wire bundle should have a white tag on it that also lists the functions of each wire. You will need to match the wires to the brake controller by function, not by color. On the brake controller, white is ground, black is 12 volt power, blue goes out to the trailer connector, and red is in from the stop light circuit on the brake switch. It

  • What Do I Need to Wire a Basic 4-Way Trailer Connector on a 1996 Toyota Tacoma Pickup
  • Since the 1996 Toyota Tacoma has separate turn and brake signals, a converter is necessary. Fortunately, there is a plug-and-play harness, part # 118379, available for your Tacoma that makes installing very easy. It simply plugs in-line with the tail light connectors behind the tail light housings. Then you connect the ground wire to a good ground point on the truck frame and you are done. I have added a link to the part and a video of it being installed on a 2000 Tacoma. I have also

  • Installing a Trailer Brake Controller on a 2012 Dodge Caravan with Tow Package
  • I spoke with a colleague who worked at Chrysler and he stated that they do not put the trailer hitch and 7-Way wiring on the Grand Caravan at the factory. That is something that the dealer installs. In any event here is what you will need to do. The brake controller will need to be hardwired into the vehicle. The white wire on the brake controller will need to get connected directly to the negative terminal on the vehicle battery. The black wire will need to connect to a 30 amp circuit

  • Installing a Brake Controller on a 1988 GMC K 1500 Pickup Truck
  • GM did not install a brake controller adapter port in the C/K series pick up trucks, so there are no plug-in adapters that will allow you to install a brake controller without having to run wires. If you already have 7-way connector at the rear of your truck, then you could use wiring kit # 5506. This kit includes a duplex wire to run a brake output circuit from the brake controller to your 7-way and to run a wire from the brake controller to the battery (via the circuit breaker) and

  • How to Find the Brake Switch Wire to Install a Brake Controller in a 2013 Ford Edge
  • Traditionally (at least from 2004 to 2007) Ford has used a green wire on the brake switch to attach to the red wire on a brake controller. However, the only way to know for sure is to test the wires using a circuit tester like # 40376. Manufacturers can use any wire they want and if they run out of the normal color they use, they grab whatever is available to keep the assembly line moving. To test the wire use the circuit tester to probe the wires. You need the one that only shows power

  • Recommended Wiring Harness for 2018 Buick Enclave and Tekonsha Brake Controller
  • For your Tekonsha Brake Controller, the custom wiring harness # 3026-P is not a confirmed fit for your 2018 model as it was for your 2011 model. At this time we don't have a confirmed fit from any of our manufacturers. It appears that Buick has changed their connector and the only fit at this time is hardwiring the brake controller. For that, you can use the Replacement Brake Control Plug-In Harness for Tekonsha and Draw-Tite Brake Controller 12" Long # 20127. I've attached a wiring

  • Brake Controller Wiring Functions to Install on a 1990 Dodge D250 Pickup
  • The red wire that disappears under the dash of your 1990 dodge D250 pickup is input from the brake switch and will go to the red wire on the brake controller. Blue is output to the trailer brakes and connects to the blue wire on the brake controller. White is ground as you know and connects to the controller white wire and the fused red wire is for power which connects to the black brake controller wire. If you had switched the other red wire and the blue wire nothing would have happened
