REDARC Tow Pro Elite Remote Head Diagram

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.

Once the Tow-Pro Elite is mounted, it will sense - via an internal 3-axis accelerometer - 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.

Tow-Pro Elite Operation

The dash-mountable control knob makes it easy to control your trailer's brakes. In addition to offering fast, simple power adjustment, this knob has an LED indicator that changes color to display different information about the controller.

Redarc Tow Pro Elite Proportional LED Display

While the unit is initially calibrating, the LED light will signal its progress. The LED display will flash green/blue as it seeks to take in information about your vehicle's direction and speed. When the display turns solid blue, the system is set and functioning completely in proportional mode. After this process is complete, the unit will remain calibrated for the next time that you tow. If recalibration is required, it will happen automatically and without LED indication.

You can use the knob to set the maximum amount of power that will be applied to your trailer's brakes. Typically, this power is only readjusted when you experience changing road conditions or if you switch over from a heavy, loaded trailer to a much lighter, empty trailer, or vice versa. To get more power to your brakes, rotate the switch clockwise. To decrease the power output, rotate it counterclockwise.

Redarc Tow Pro Elite Brake LED Intensity

When you apply the tow vehicle's brakes, a red LED light will inform you that power is being sent back to the trailer brakes. As you increase the power with the control knob, the light will glow brighter, indicating the increased braking power.

Should you want a higher degree of control over the trailer's braking, you can use the control knob to switch over to user-controlled braking mode. To change modes, rotate the knob counterclockwise and apply your vehicle's brakes. Then push down on the remote knob twice (2 times within 1 second) and release the brakes.

Redarc Tow Pro Elite User Controlled LED Signal

User-controlled mode is signaled by a green LED. In this mode, the Tow-Pro Elite will apply your trailer's brakes with the same preset amount of power each time you activate the brakes in your vehicle. While in user-controlled mode, the braking power can be adjusted by turning the control knob in the same manner as when you are in proportional mode.

Having this level of control over your braking is particularly beneficial when overlanding or towing a trailer off-road because you may need to alter the trailer's braking based on the specific terrain and situation that you find yourself in. Set the power low if you're towing through sand or mud so that the trailer doesn't stop with too much force and act as an anchor on your vehicle. When on a steep descent, set the power to a higher level to ensure that the trailer's momentum doesn't cause it to push against the tow vehicle.

The Tow-Pro Elite gives you easy access to manually apply the trailer brakes without using the tow vehicle's brakes. To engage the manual override, just push down on the control knob. This will activate the trailer's brakes, helping you to control its momentum.

The manual override will activate your trailer's brakes differently depending on the mode you have selected. While in user-controlled mode it will apply the brakes at the power level set on the control knob to ensure a predictable braking response. When in proportional mode the manual override will activate the trailer brakes in a light manner, which is great for limiting trailer movement while you're cruising.

Simple, Out-of-the-Way Installation

Unlike most proportional controllers on the market, the Tow-Pro Elite has almost no mounting restrictions. It comes in 2 pieces - the main electronic unit and the control knob. Because the only part that you need to be able to access is the control knob, the main unit can be mounted in an out-of-the-way location. So you no longer have to worry about a bulky brake controller scraping against your leg or causing interference with your vehicle's lower airbags.

Redarc Tow Pro Elite Dash Mounted Remote Knob

The dash-mountable control knob can be mounted in a convenient spot that is easy for you to see and access. This can be a blank switch panel, an open area on your center console, or wherever there's space on your dashboard. A universal mounting panel (331-TPSI-001 - sold separately) is available to ensure a clean, from-the-factory look. Custom-fit panels are available for certain vehicles as well.

REDARC Tow Pro Elite Flexible Installation Position

Once you have determined where to mount the control knob, you will want to find a good place to install the main unit. The only mounting restriction for the unit is that the included 3' plug-in cable is able to reach between the main unit and the knob.

Thanks to the 3-axis accelerometer, the main unit can be positioned at any angle. There is also an active calibration feature, which constantly evaluates the direction of travel of your vehicle. This enables the unit to recognize any change in position that may have resulted from potholes or back-country roads and automatically correct itself. Because this feature can read the direction of travel, the main unit can also be mounted facing any direction, allowing for even greater flexibility in mounting.

REDARC Tow Pro Elite Harness

The included wiring harness hardwires into your vehicle's wiring and then plugs directly into the main unit. You can also use a vehicle-specific wiring harness to cut down on installation time. These harnesses are available for most newer trucks and SUVs. One end of the custom harness will plug into your vehicle, and the other end will hardwire onto the Tow-Pro harness that plugs into the main unit. Once all connections are made, securely mount the box using screws or double-sided tape. Do not zip-tie the box to wiring or cables that can shift as you drive.

TrailerMate Custom Wiring Adapter for Trailer Brake Controllers - Pigtail
part number: TM75273

Ease installation of your electric trailer brake controller by using this custom wiring adapter. Simply connect the 4 wires of the harness to your brake controller and then plug the other end into the built-in port beneath your vehicle's dash.


  • 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
  • Stranded copper wires ensure long life
  • Limited lifetime warranty

Installation of TrailerMate 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 port on your vehicle's built-in brake control wiring harness. The harness is located underneath the dash, to the left of the steering column, and it is taped to another harness near the emergency brake pedal.

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.

Product was exactly as advertised. It turn out to be more difficult to find locations for the controller and control knob than expected but worked out in the end. Tommy in product support was very helpful. Vehicle Lexus GX470. 522245

I installed this into my 2018 Tacoma. I'm not super mechanically inclined, but this was a very easy install. I looked at an article on an online forum and watched the etrailer video of them hooking it up to the 4-Runner and that was all I needed. I used tthe brake harness adapter that goes from the brake harness into my old brake controller. (Tekonsha 3017P). I connected the wires from the brake controller to the adapter with butt connectors. Everything else was plug and play. I found a spot under the dash and used velcro to secure it. The remote knob fit into the dash no problems. I used their dash plate to mount it into one of the blank spots. I took the truck out with my trailer and everything worked like a champ. I couldn't be happier. No more banging my knees on the old brake controller that was mounted in a crappy spot before. The remote knob looks like it's from the factory. 529272

This product is well worth it. I installed it on a 2015 Toyota 4runner for use with a travel trailer. I decided to go with the RedArc Tow Pro Elite for aesthetics. Installed very easily and looks stock when in Auxiliary location. Traveled 1,400 miles a few days after the install with the trailer and it did GREAT. Couldn't ask for better. The employee's at etrailer were extremely helpful when deciding what product to purchase and shipping was faster than estimated. 495172

Great idea, makes for a very clean look, lets you put the trailer brake control almost anywhere on the dash or console. One does not have to lean down to operate the brake controller anymore. It installed nice in a 2018 Silverado, good thing the box can be mounted in any position, hard to find room under the dash in new trucks. 478028

This thing Is very slick!!! Compared to the other controllers I've used in the past this so much nicer. Install is more advanced as I had to take part of the dash apart on my pathfinder to get at the back of the blanks. But sooo much nicer than drilling holes in you dash and banging your knees on this ugly box that is always in the way. This looks way closer to OEM. One great thing is that the box can be mounted any way and hidden. It takes the unit a little while to learn, about 20 brakes or so. My only complaint would be there was no install blanks available for my type of vehicle. So I used the universal which sits over the blank hole instead of flush. This is a minor detail overall compared to the alternative. Over all works very well, looks very slick, and is very user friendly. One thing I really like is how easy it is to adjust up or down on The fly, just turn The little knob. Even if your not looking at it you get a satisfying little click. The only one I would buy now that I have one. Recommended, high quality, and worth the extra money. 515026

Installed in 2018 Jeep Grand Cherokee Trailhawk. Easy hook up to Jeep OEM towing harness. Wire colors were different between Jeep and Redarc but easily matched between the two plugs and documentation provided. Located control switch on shift console with control module dial anchored in location as videos show. Needed to grind down plastic cross hatch stiffener on underside of shift/cupholder console using Dremel tool to obtain a flat surface to mount and anchor the control switch. 547472

This was a researched and implemented purchase to my 2018 Toyota Tacoma PU! Very satisfied with the installation "look" and functionality. I also purchased the plug and play wire harness that utilized the OEM "Tow Package" wire connection. Would recommend this over the "other" aftermarket units available as this looks factory "I think even better than" what Toyota offers in the Tundra line of units. Suggest if you are in the process of selection view all the [on-line] videos on the unit. Review and study the PDF instructions for familiarity. As an FYI I had the unit installed by a local "Pro" show whom had never seen a Redarc unit. They now want to offer and carry it for customers. 517607

RedArc install on 2008 Toyota Tacoma. The RedArc works great. Clean install without the ugly control box to knock your knee on. Very well constructed. Trial run was a trip from CA to MN through the mountains. Brakes worked smoothly and didn't even know the trailer was there. 492658

The REDARC cost more than other brands, but is much more user friendly and worth the extra cost considering your life will depend it. My experience with etrailer was unbeatable: best pricing and knowledgeable folks who actually answer the phone. My unit shipped free and arrived in 3 days. 563284

Just installed the Redarc brake controller in 2008 Silverado. First, it is nice and compact. Watched the video to install and tried in my truck. Had a hard time getting it to fit in the same space. When I tightened it down, it came apart. Had to take everything apart and reinstall making sure to keep it flat. Not easy as my truck has no flat surface to mount it. Mounting the control knob was easy as there was a nice space to the left of the column in the lower panel. To take the panel off ,remove the bolt holding the brake release, it makes it easier. Have to finish wiring and will review again after I pick up the trailer. Took me more than 2 hrs. so far, but I am 72 and can't limbo anymore. 574986

Came with a harness to plug into a factory connector, which made installation pretty easy. However.. The knob assembly comes with a template, which is incorrect. Got the hole reamed out so it fits, only to find out the washer that is supplied makes the mounting surface so thick, you cannot mount the assembly. Had to mount without the washer, and you'd never know it. I just installed it, so have not hooked up a trailer to it yet. 474562

Just bought the Redarc Tow Pro Elite. Installed it in less than 30 minutes. The controller hides in the glove compartment. Hooked up my new trailer and the Redarc “auto learned” in a matter of a few minutes of driving. Didn’t take long for me to forget that the trailer was back there, even when hauling 4 horses 558135

The Redarc Tow Pro Elite was installed on our 2016 Honda Pilot this was exactly what I was looking for it looks like a factory installed brake controller. Pros: The Redarc Tow Pro Elite was easy to install match the wires with the harness wires and that’s it this is a very nice system .The unit is small which is great gives you multiple options to mount the unit under the dash. Cons: the 90 degree fitting on the Ethernet cable gave me some trouble with installation Operating: To see if unit is operating correctly it needs to be connected to a trailer. Once connected to the trailer apply brake and the system will light up and follow the instructions to setup you unit. 2016 Honda Pilot Installation: I mounted the unit above the emergency brake under the dash there was plenty of room to mount it there .I was able to secure the unit using heavy duty zip ties and industrial two sided tape. I used the recommended butt connectors to attach the wire from the Redarc to the Quick connect wire. Once connections were made the system was all hooked up. FYI on installation :If you ordered the trailer hitch and had it installed from the dealership they should have given you the extra arts from the Kit to install a brake controller. To save a few bucks it comes with a quick wire harness and a 20A mini fuse. The fuse is very important you need to install it in the secondary fuse box under the dash follow instruction from the Kit my system didn’t work because fuse was not installed. Another FYI is when installing the switch reverse Ethernet cable use the straight part not the 90 you run into issues because on the backside there is a metal plate and it wont allow the you to push the switch in all the way and it wont sit flush. 498083

Cleanest install over the typical knee killer hung under dash. Wasn’t super impressed by install kit offered for traditional unit install for my 2014 Tundra. Found this unit on website while pricing out, this by far is the way to go. I got the switch plate kit for the best look (I painted lettering) and made a ridged mount bracket for the unit (solid mount required from the controller, can’t just tie to harness). Took me 2 hours top to install and it’s as close to a factory unit as you can get. Switch is mounted under the ac controller and the unit is mounted on left side of steering column hole was already on the truck. Only drilling was on the bracket I made. I had the factory harness to plug unit into truck and wired it to the one from REDARC for the controller. It’s well worth the effort. 571008

I just got this unit installed! Etrailer made it plug and play easy for me by providing the correct pigtail adapter the first time. It took awhile only because I needed to figure out where I was going to locate everything. Once that was decided it went quickly. Reading the directions goes against the “man card” possibly but it was helpful to know how the unit learns its’ orientation. After a short drive with many brake applications it was set to do its thing. Works wonderful and it is really nice to not have a knee knocked under the dash panel!! 515243

The controller was received promptly and installed in our 2018 Winnebago which is on a Ford E450 chassis. The control knob was installed in the center of the dash next to the battery jumper switch and the control module was attached to the drivers side of the engine cover out of the way of the drivers legs. It was connected to the factory brake controller connector via the 3040P connector spliced into the Redarc module connector. It was tested by the method described in the manual and so far seems to be working OK. Will not be towing a trailer for some time so can't give any feedback on actual usage at this point. 480818

The etrailer team made this install super easy. I was able to dremel out the stock Tacoma dash blank to make the brake controller fit. The dremel with the right bit works great. I did have a bit of trouble locating the correct connector on the wiring harness but once it was located the rest was a breeze. I'm still not completely sure on the controller mounting location but it's up and it's secure. I get to test the controller out soon so I'm hoping for good results. 486729

I am disappointed with the "Dash Mounted Remote Head Assembly". When installed according to directions, if the unit is tightened as per instructions it will not allow the override or switching between manual and proportional modes. The only way to continue to be able to depress the knob is to leave the head unit loose. The head nut cannot tightened per instructions and still allow mode changes. Unit was installed in a 1998 Ford F150 and placed on the dash near the steering column. 570526

I contacted our Red Arc contact and they believe the section of the dash you have the knob installed into is too thick. You will need a mounting panel part # 331-TPSI-001 to allow the control knob to depress all of the way. Please keep in mind this mounting panel will only install into dashboards that are less than 9/32 thick.

Installed the Redarc Tow-Pro Elite Trailer Brake Controller in my 2016 Chevy Colorado Attached are the pictures. I put it next to the light control knobs where it could be seen from the drives position through the steering wheel spokes. 499943

I have installed and used several different trailer brakes over the years, the installation of this unit was easy to moderate, but the operation of the brake system is far superior than other units I have used. I installed the unit in my 2016 Chevy Colorado v6 and did a recent 340 mile round trip, at freeway speed and then up a and back down a, steep at times, mountain highway. Often, I find I have to turn the brakes output force down when I get off a freeway and into town if the brakes have gotten warm and get grabby. I found this unit didnt require this as often, and sometimes not at all, and when it did it was easier to do so. The output knob has clicks you can feel, so you can turn the unit down 3 clicks when you in town and then up 3 clicks when you get back up to speed on a highway. It has numbers on the dial, but bottom line is you dont have to take your eyes off the road to look at it to make the adjustment! I used the Proportional mode for the trip and it was much smoother than my last unit, especially handling the rush hour stop and go traffic didnt get grabby. The ability to switch on the fly between Proportional and User Controlled operating modes worked flawlessly, as I tested it on the dirt road when we got to camp. I did laminate the card they provided on how to switch modes, and put it in the glove box, as it is a 4-step process, and I typically can only remember 2 steps of any processes after about 2 days just me. Also, the automatic parking brake if you stop for a while worked very well and was a nice extra I didnt realize I liked and needed. The fact you can mount the controller Main Unit and the Remote Head Assembly in different places and in any position made the installation extremely nice. Under the drivers kick panel, of my truck, is a metal plate that can be unbolted, so I was able to mount the Main unit on this plate while working on my work bench, much easier! I was also able to mount the Remote Head in a place I could see it while driving. Again, I found this was not as necessary as I thought, because of the click feature, but you need to mount it where you can find it quickly if you need to push the Manual Override Mode button to stop trailer sway. Because I could mount the Remote Head where desired it gives the final installation an OEM look, which is nice and not in the way. The only issue I had was the Remote Head unit I received was faulty. Once I pushed the Manual Override Button in it got stuck and staid that way unless I pulled on it faulty return spring. The manufactures sent a new one right away, and the new one works with no issues. The only sort of hard part with the installation is you have to take some care mounting the Remote Head unit, as you have to drill a large and small hole very close to each other, and the spacing tolerances are very tight. To do this I drilled the large hole 1st. The unit comes with a plastic washer with both holes in it, so I put the drill bit back in the large hole, put the plastic washer over it. This let me use it as a guide to locate and drill the small hole. I had to drill the small hole 1st with and undersized bit, that fit through the small hole. You then have to go back with the correct sized bit and finish drilling out the small hole it has a tab that goes needs to go into the hole.

  • Where to Mount Redarc Tow-Pro Elite Brake Controller on 2020 Chevy Silverado 1500
  • The Redarc Tow-Pro Elite Trailer Brake Controller # 331-EBRH-ACCV2, along with the Plug-In Adapter # 3064-P for easy installation, is an excellent choice for your 2020 Chevy Silverado 1500. One of the many benefits of the Tow-Pro Elite is the small, unassuming profile of the control knob itself, which basically allows it to mount anywhere you have the space. I went through our customer reviews and it looks like there should be a great location on the left side of the steering wheel on

  • If your 2018 Jeep JL Wrangler Unlimited is equipped with the factory tow package, which should include a 7-Way connector at the rear bumper (you can check to be sure), the only additional components you will need outside of the Redarc Tow-Pro Elite Brake Controller # 331-EBRH-ACCV2 itself is the Tekonsha Plug-In Wiring Adapter # 3073-P and Tow Pro Adapter # 331-TPH-017.

  • Comparing Curt Spectrum and Redarc Tow-Pro Brake Controller for 2018 Toyota Tundra
  • Both the Redarc Tow-Pro Elite # 331-EBRH-ACCV2 and the Curt Spectrum # C51170 Trailer Brake Controller offer a sleek OEM design that gets away from the traditional knee knocker mounted options that take up a lot of space in the cab. Between these two brake controllers though I do recommend going with the Redarc # 331-EBRH-ACCV2 for a couple of reasons. The first reason is an aesthetic one. One of the main benefits of both controllers is the subtle design that tries to blend in with

  • Recommended Trailer Brake Controller for 2019 Toyota Tundra SR
  • At this point (June '19) trailer brake controller makers like Redarc have not had time to get their hands on the 2019 Tundra SR for doing test installations but there is one trailer brake controller that I can assure you will work fine for you so long as your truck has a functioning 7-way trailer connector like # PK11893. The Curt Echo # C51180 installs without any cutting or splicing of wires in the truck. The installation consists of plugging it in at your 7-way, plugging the trailer's

  • Best Brake Controller Recommendation for 2019 Jeep Cherokee
  • The best brake controller I can recommend for your 2019 Jeep Cherokee is the Redarc Tow Pro part # 331-EBRH-ACCV2 with the custom fit harness for your vehicle part # 3014-S. The reason I recommend this brake controller is because unlike other bulkier brake controllers the only thing that mounts on the dash or center console is a small knob that is used to control it. If you check out the picture I attached you'll see how small of a foot print the controller takes up. The rest of the controller

  • Where to Mount the Tow-Pro Elite # 331-EBRH-ACCV2 on a 2017 Chevrolet Silverado 1500
  • The great thing about the Tow-Pro Elite # 331-EBRH-ACCV2 is it's versatility when it comes to choosing a location to install the control knob. Since the control knob is smaller and the box that it connects to learns the direction of travel as you drive you can virtually mount it anywhere. If you check out the attached picture and installation video you can see that we mounted it in the center console for one application. If you would like a clean looking installation you can use the

  • Brake Controller Recommendation and Install for 2020 Subaru Ascent
  • I'd give the Tekonsha # 90195 the edge for ease of use. The full LCD display provides the status of your braking system at a glance, while the # 331-EBRH-ACCV2 Redarc Tow Pro Elite uses colored LED's to indicate problems. The display of the P3 is much more intuitive and user-friendly. However, some folks absolutely hate the appearance of a typical brake controller and want it to be as hidden as possible. If you fall into that camp, the Redarc Tow Pro Elite might be a better choice. Performance

  • Brake Controller Installation in 2019 Ford Ranger
  • We have not yet (as of April 2019) had a chance to install any wired trailer brake controllers on a 2019 Ford Ranger so for guidance I checked with my most trusted brake controller expert at Tekonsha. Based on what I could learn about the truck if the Ranger has a factory-installed 7-way it should have a standard brake controller connection port above and to the left of your left knee when seated; this will be near the kick panel. You will want to look for a connector that matches the

  • Should Proportional or Time-Delayed Controller be Used for Towing a Horse Trailer with a 2018 Tacoma
  • If you are towing on level ground or rolling hill areas then a proportional brake controller like the Prodigy P3 # 90195 is preferred. This kind of controller senses the deceleration of your tow 2018 Toyota Tacoma and applies the brakes in your horse trailer at the same time and with the same intensity as the brakes in your Tacoma. This gives you a very smooth braking experience that your horses will appreciate. Really one of the only times that a time-delayed controller like the Pilot

  • Best Brake Controller for a 2019 Ford E-450 Cutaway
  • The best brake controller for your 2019 Ford E-450 Cutaway is the Redarc Tow-Pro Elite Trailer Brake Controller part # 331-EBRH-ACCV2. The Tow-Pro Elite is very similar in design to a factory trailer brake controller.

This will provide a very clean look and will allow you to mount it in many different locations whereas a standard brake controller

  • Best Hidden Brake Controller for a 2018 Jeep Grand Cherokee
  • I do have a similar type of brake controller for you but the Reese Towpower Compact IQ Brake Controller part 8508700 is just not a very popular option hence why we do not currently carry this controller. Instead, I recommend the Redarc Tow-Pro Elite Trailer Brake Controller part # 331-EBRH-ACCV2 which has the same hideaway design as the Compact IQ. The Tow-Pro Elite is one of the most innovative controllers on the market. The control box that this controller uses can be mounted anywhere
