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 (sold separately) 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.


For assistance in properly wiring the Tow-Pro Elite, please refer to the diagrams below:

I really like this trailer brake system because it was very easy to install and the only part of the system you can see is 1 control knob mounted in the dash. More importantly the system works great. I towed my 23ft trailer 11k miles this last year without any problems.I really liked that i could adjust the brake force as i drove with just the turn of a knob.I increased the force going down long steep hills such as in the Rockies. Great System !

I installed this to tow a 4.5 x 9 off road teardrop trailer with 31 inch tires and 10 inch electric drum brakes. The controller works super well. It has dual modes so that you can select between on road and off road braking profiles. The on-road is proportional and senses the inertial differences and comes on more gently while the off-road mode is instantaneous with user-selected intensity. On steep, rocky, off-camber, 4-wheel-low tracks this controller is awesome, keeping the trailer from trying to push the tow vehicle down the hill or sliding sideways. You can easily change the braking force on the fly by turning the dial, which is helpful when traction conditions change on the slope you are on. I actually use that feature from time to time, i.e. it is not a theoretical advantage. On regular bumpy off-road conditions the brake application is very smooth and not affected by the bumps. On-road manners are also very smooth and predictable. Mounting is fantastic because you can hide the controller under the dash, out of the way, so your knees don't hit it, then put the dial wherever it is easy to see and reach. I put it on the console at first then moved it a month later onto the dash. Attached picture is for a 2017 4Runner dash. The dial uses a standard size for switch gear in off-roading, so you can buy an enclosure for the dial if you want to (carried by etrailer). My only complaint is that it can be hard to tell what mode you are in by the dim light on the control dial. After using it a while, though, it is pretty easy to just feel whether you are in proportional or user-select mode. This complaint in no way is enough to drop down to 4 stars. This is a really nice controller.

Very easy to install! The video provided by etrailer is incredibly helpful. However, it needs to be updated. First, the plug and play harness that is featured in the video is now truly plug and play. There are no wires to be cut and connected, so save your money on the blue and orange heat connectors the video uses. Second, DO NOT BUY THE SWITCH INSERT USED IN THE VIDEO for a 2020 Toyota 4Runner (or really any year model 4Runner) get part 331-TPSI-002 it will insert into the dash without drilling or needing glue. I bought the one recommended and found out about the correct one and had to order it from the A to Z online retailer. Overall a very easy install. And looks very OEM!

Easy install. I bought the 2020 Toyota Tacoma specific patch cable for the controller head unit. As well as the controller potentiometer dash mount. Easy installation. I used 3M double lock velcro strips to attach the controller head unit to the side of one of the hard plastic wiring harnesses behind the driver left side kick plate. The wiring harness was secured with a metal bracket. Prior to install I had to remove three screws, one of which is behind the driver side kick plate. Plus two screws along the bottom of the trim piece that surrounds the steering column along the bottom of the dash. I pushed out the dash blank then pushed in the new "Trailer Brake" blank I purchased,with the redarc controller potentiometer mounted. I did not use the supplied grey ring which came with the redarc unit. I think that would only be used if you had to drill into a dash to mount it. I then made the connections and replaced all the trim pieces. Real easy. Took me about 20 minutes to install. Including reading the installation instructions. Looks like a factory install. I've not tried the unit with my trailer. I plan to this weekend. I'm sure it'll work as advertised. Shipping from e-trailer was fairly quick. Everything came packaged well. The redarc instructions were good. During the programming phase I only noticed the Blue LED would light once when I would apply the brakes. It did this for about 5 brake stops. Then afterwards no more blue light when applying the brakes. I assume that means the units controller head orientation is now memorized and will function as designed once I connect my trailer. The instructions aren't too clear in that respect. But other than that it was a painless install. And looks really good.

I Installed this in a 2011 Ford Expedition. Since I didn't have 4 wheel drive there was a change holder in the dash where the 4x4 selector would have been. I took it out and printed a switch mount with a 3D printer. Very happy with the factory look. Screwed the control box to the steel behind the panel underneath the steering wheel. Every thing works great.

I have installed the brake controller and did prelim tests all seems to be OK! I used a blank panel that was not used in my Honda Pilot, that took me awhile to trim and file the panel, I was going for a OEM look. The control unit I mounted to the parking brake assembly. The wiring was easy as I had a pigtail from my trailer wiring harness and the pigtail that came with the unit. When I fit the remote control in the panel it fit OK and the knob allowed the switch to operate correctly for the half dozen times I tested it. Once I installed the panel-remote combo in the dash all seemed well but then I noticed the knob seemed to slide down the reomte control knob a bit further and would not allow the switch to operate, I guess during my other trials it must not have bottomed out. I used some plastic shim stock I had and put that inside the knob (approx 30 mils thick) and the switch started to operate correctly. We still have a few weeks before we pickup the trailer, but for now it looks like the unit went through it's calibration routine and is ready to control the brakes once we get the trailer. One thing to note the manual mentions sleep/breathing mode this just seemed to be a single cycle rather than a repeating cycle, but I was just using a test lamp.

Working out good, its doing a nice job!I We used it on about 7 trips works very good. I like it is adjustable! Im glad I purchased it once installed everything is out of the way and the LED only glows when the trailer is hooked up.

Installed this on my 2019 Tacoma TRD-OR. The included wiring harness made this plug and play. Hardest part was trying to find a suitable location to mount the unit. I used Scotch Interlocking Fasteners (velcro like) to fasten it under the dash to the left of the steering column to a wire panel. Also used REDARC TPSI-002 Tow-Pro Switch Insert to install the control knob into the lower center dash in an empty switch spot. Nice clean low profile set up. Very pleased so far, will be testing the unit out this weekend.

Installed a REDARC Tow-Pro Elite trailer brake controller today in my 2015 Jeep KL Trailhawk with a factory tow package which I am using to tow a 22' Falcon F-22RK travel trailer. Found a perfect place to install the multi-function Tow-Pro control dial. There is a storage box below the light switch on the left side of the steering wheel that pops out to access a fuse panel inside the dash. I cut some rigid insulation as a backer and a thin piece of brushed metal as a mounting plate to mount the multi-function switch inside the storage box. Works very well and disappears when not in use. Have not towed yet but will update this review if there are problems.

Review of Install on a 2015 Tacoma - Actual installation time, about an hour. Time taken to figure out how to remove the foot rest, left kick panel, and to locate the factory installed controller harness plug, about another hour. The factory guy did an excellent job of shoving the harness connector up, behind and on top of everything so if you did not know it actually existed you'd have given up (small hands would be helpful here). I finally found my connector on top and behind the largest bundle of wires running vertically (it was white). I found a diagram on this site (https://www.etrailer.com/question-281269.html) showing the factory wiring harness and Tow Pro color conversion/match up. The colors were different on my harness but the conversion was the same (see my upload). Of course YMMV and I would not accept what I did without triple-checking it against other sources. I mounted my controller on the trim panel between it and the transmission hump. I used heat shrink crimp connectors to connect the factory harness jumper wires to the Tow Pro provided harness wires. I mounted the remote controler in an unused slot to the left side of the steering wheel (part 331-TPSI-007 purchased from etrailer). It fit perfectly - but you can't assemble it in advance since the controller is too large to fit through the hole in the dash (don't ask me how I know this). I cannot vouch for the Tow Pro's operation as I've not used with a trailer yet, but per the instructions, the unit seems to be functioning as it should without a trailer attached. I hope that this review helps someone save some time with their install.

I received my order today at noon (as predicted & on time). It was very easy to install (thanks to the Redarc Plug-and-Play Wiring Harness for Tow-Pro Trailer Brake Controllers)! The whole operation took about an hour! It looks like factory now on my 2018 Silverado, I'm happy with how it looks and works!

I was hesitant to buy this because of the cost, but I'm glad I did. My Explorer is very limited on space, so a conventional brake controller was not feasible. I mounted the knob/switch on the dash, and mounted the controller hidden away under the dash. I am very happy with how clean the installation is. Calibration was easy, the controller does all the work, you just drive.

The Redarc Pro-Tow Elite I ordered is everything I hoped it would be. I also ordered the optional plug and play wiring harness and dash plate for my 2016 Tacoma and it was truly a plug and play system. After looking at how to videos on YouTube it only took me about 30 minutes to install. It works great and almost looks like it was factory installed. Joshua K very helpful in making my decision. Thanks to all at etrailer.

I can't say enough great things about this controller. I love the discreet dial for adjusting the braking force, and the installation video by eTrailer for my 2016 VW Touareg was exactly what I needed to install this in about an hour. The video even explained the OEM connector parts that I needed from my VW dealer so the installation went perfectly. Highly recommend this to anyone.

I really like how low profile this switch is. Once installed it's very out of the way but still accessible. The hard part for my Silverado was finding a spot with 2.5" of clearance behind a panel for the actual switch housing. Finally found a spot and I'm super happy with it now

The 331-EBRH-ACCV2 Redarc tow brake controller was very easy to install into my Jeep Gladiator. I chose to mount its dial in the lower left dashboard facia simply due to ease of backside access with sufficient clearance for the TPSI-001 switch insert, I did have to trim the back side flanges off of the access cover as is mentioned in the etrailer how-to video, and I used two self-drilling screws to mount the controller as seen in the picture. Note that I used the 3073-P OEM ($xx) harness along with the 33-TPH-017 ($xx) connector converter and the TPSI-001 ($xx) switch insert, but none of those were actually necessary for this installation and can only be used if the JT/JL was built with the tow package wiring included; the Redarc controller comes with its own connector that can be easily hardwired into the vehicle harness. I added the switch insert simply because it makes the installation look more professional.

Installed Redarc on a 2017 Jeep Grand Cherokee. The installation went well - not necessarily straightforward and easy but got 'er done! It's easy to gain access to the area. First open the door forward of the shift and lift the horizontal panel up out of the tab holders. Then open the center glove box and pull up on the panel to release more tabs. Once the panel is free of the tabs, disconnect three wire connectors. Somewhere it said to release the boot around the shifter, but I found it easier to lift the panel as high as possible and push the boot out of the way from underneath in order to get access to the T-25 bolt holding the shifter on. The panel is now free. The Terrain module can be removed by squeezing 4 clips from underneath. The biggest issue was finding an exact spot where it would fit. The place I selected had a roundish flat area underneath the panel but I had to move it more to the passenger side than what was ideal from underneath. In the end, the plug interferes with a protrusion on the shifter but not enough to worry about. Also, the thickness of the plastic was too much to allow the switch to protrude enough. So I Dremelled the back area as much as I could. That wasn't enough so, in talking with Redarc, they said it was OK to remove the inner guts of the switch and sand down the hold offs on the switch. That worked. Note that the instructions say to use a spade bit to drill the 3/8" hole - I just used a regular drill bit but the plastic got buggered up because of it. The electronic module fits nicely at the front end of the area. I took out one bolt and added a few washer to make it sit flat. Haven't had a chance to use it yet with my RV but I'm sure I'll be happy with it. etrailer always does a good job with any purchase - it took longer than I expected, but that may be standard these Covid days.

This is a high quality item, well worth the higher price. The small control head is able to be installed in any location and gives an OEM appearance. The main box only needs to be mounted securely in any position to work properly. It can be placed completely out of sight. I placed a follow up order for a specific adapter plug for my GMC Sierra 1500. I recommend ordering the adapter with the controller to make it a splice free, plug in installation.

I am still very pleased. I mentioned the higher price in my review, but a year later I dont remember the price. The lesson is to buy good merchandise for long term satisfaction.

RedArc Tow Pro Elite brake controller I have a 2020 Toyota Tacoma SR5 with factory installed tow pkg. I did not want a brake controller box mounted externally on lower dash leaving no room for knees. The Redarc Tow Pro Elite is designed to avoid this inconvenience. The main unit can be mounted anywhere out of sight and uses a connection cable that plugs into a small control knob mounted in one of the knock out dash panels. With the help of online videos I was able to install this product soon after it arrived. I like the features RedArc builds into this device like choosing between proportional braking, user controlled braking and manual override, each with distinctive blue, green or red LED indicators. Fantastic engineering designed to work and look like OEM.

Working great for a year. Install was easy took me about an hour and I am no expert. I tucked the controller in the left side panel with some short screws and zip ties. I love that the dial is so tiny. I hate the ones that are under the dash and snag on your knees. My biggest problem was actually finding the wire bundle under the dash. Great product and my brother bought one shortly after me because he liked it too.

Product arrived a day earlier, installed the same day, not used with a trailer yet. That being said, to me this product is a no brainer due to the 3 axis accelerometer that gives a lot of option for installation . Also no brainer to buy from etrailer due to their variety of resources (photo and video) to aid with the setup. The spot where I installed mine was actually suggested in one of their videos and worked perfect

This is a great product! My last brake controller was an under-dash unit and I kept bumping it with my knee getting in and out of the vehicle. This time, I wanted something effective, but inconspicuous and this fits the bill perfectly. I installed this in my 2012 Volkswagen Touareg. The control button is mounted next to the headlight switch and it looks like it belongs there. Installation was moderately easy. I mounted the unit on a steel cross member under the dash where it cannot be seen. Very solid mount. By far, the most challenging part of the process was just finding the factory wiring under the dash! I swear the VW assemblers go out of their way to hide it just to torture people like me. For any of you that are installing this (or any) brake controller in a Touareg, don't give up on finding the harness. It's in there! In the end, I couldn't be happier with this controller. It's easy to use and it works great. Highly recommended!!!

I only gave the controller 4 stars because I have not used it towing a trailer yet, only tested it on my friend's trailer for proper operation. I just purchased a 2019 Toyota Land Cruiser and plan to purchase a 23 foot trailer to pull with the Land Cruiser. I took my "old" brake controller out of my other car and planned to use it for the Land Cruiser. I found that the places to put the "old fashioned" controller were very limited in the Land Cruiser and it would get in the way of the driver's knees. So I did some internet research on what I could buy to avoid that problem. I found several reviews comparing the TowPro to other controllers and then I found a youtube demonstration of how to install one in the dash panel of a 2018 Land Cruiser. I ordered one and installed it very easily, with the extra insert that replaces a blank insert in the left panel of my new dash. It looks great, it is out of the way of my knees and easy to reach. It appears to set up without any extra work by me, which I like. The only small problems I had were: 1. I needed to be shown how to take the dash panels out and reinstall them by the Toyota Dealer; and 2. The small plastic ring washer that comes with the switch was not needed in the install with the insert. It took some research on line to figure that out. Other than those two things the install was easy and was completed in about 2 hours, which included connecting the wiring from the TowPro connector to the Toyota connector for the under the dash connection for lights and braking. OH yes, one more thing. If you are going to install this in a Toyota Land Cruiser, I could not find anyone that knew exactly where the underdash connector was, not in the manual and not at the dealer. I found where by looking at the youtube install on the 2018. So far I am very pleased with this equipment. With some actual use I may even give it 5 stars.

I ordered this brake control plus a 7 pin installation kit. etrailer makes everything so easy. Everything, I mean everything I would need came in the kit, and a few spares because they figure you might mess up. I have used etrailer for several projects and they always over deliver.

Still worth every penny. I still recommend it to anyone who asks about brake controllers.

I got this because it had both proportional and off-road options for brake control, and that it could be mounted remotely. That is has a 3-axis sensitivity was nice that it could be mounted in any position unrelated to the orientation of the truck - this opened up a lot more mounting options. I mounted the controller under the center console and ran the dial to a safe place under than hand brake. I cross-threaded the dial when mounting it, but was able to correct the damage, so be careful that you thread it on carefully. My issue was that the hole I drilled was a tad too small and it was hard to turn the nut and push it in at the same time. Who has metric size drill bits in this country....? It needed a 10mm. This was a very expensive controller, but remembering the little annoyances of my previous "timed" controller I thought this would be a worth while investment and much safer. I will update after I log in some towing miles.


Comments
On the first trip I felt the $208 was well spent, versus a cheap $38 timed controller, and I have mainly been just towing a little cargo trailer that came brakeless originally. It is so nice that the trailer brakes work smoothly and brake according to how hard the truck is braking. I cannot even tell it is braking because it is so smooth. The only issue I had was it froze up somehow in the software and just showed a red light. I unplugged the trailer for 2 mins then re-plugged and that was the fix, this is not in the trouble shooting list, but is how you would fix a junky microsoft enabled computer at home, so it made sense, maybe microsoft wrote the software. haha. I also like that all I see is the little dial, not the entire controller unit. The controller is hidden under the plastic armrest along with all the wires. I mounted the little dial under the e-brake lever so there is no chance to kick it, sit on it, or bump it as it looks like a big hit could break it. I can see it good enough to matter, but really never need to even see it while towing other than to see blue that is is good and not red which would mean something bad... I strongly recommend a proportional controller.

  • 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.

  • Redarc Tow Pro Elite Brake Controller Recommendation for 2018 Toyota Tacoma
    To install the Redarc Tow-Pro Elite part # 331-EBRH-ACCV2 in your 2018 Toyota Tacoma only requires the correct install harness # 3031-S. This connector attaches directly to the connector you have under the dash of your 2018 Toyota and the other end wires to the brake controllers wiring with butt connectors. The colors all match between the two harnesses. The smallest mount plate we have for this controller is 1-1/4" tall x 7/8" wide and is part # 331-TPSI-002.

  • How to Make Custom Adapter to Install Redarc Tow Pro Elite on 2020 Toyota 4Runner
    You are correct, there isn't a custom wiring adapter available that would have a plug to connect to the Redarc Tow-Pro Elite Trailer Brake Controller # 331-EBRH-ACCV2 on one end and another plug to match the factory brake controller port on your 2020 Toyota 4Runner on the other end. Fortunately, there's a simple way to make one.

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...

    The easiest solution to install the Redarc Tow-Pro Elite Trailer Brake Controller # 331-EBRH-ACCV2 you referenced in your 2017 Chevy Silverado 1500 is going to be with the install harness part # 331-TPH-010 which plugs directly into the controller and into the port under the dash of your truck without any splicing required.

  • Recommended Brake Controller and Wiring Harness Location for a 2018 Nissan Armada
    I recommend installing the Redarc Tow-Pro Elite Trailer Brake Controller # 331-EBRH-ACCV2 on your 2018 Nissan Armada because it offers both a user-control mode and a proportional mode for varying towing applications plus it installs in such a way that only the control knob will be visible. This combination gives you a great brake controller and a clean looking installation that won't get in the way. The user-control mode is equivalent to a time-delay controller where it brakes at a preset...

  • 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...

    To install the Tow Pro Elite brake controller part # 331-EBRH-ACCV2 in your 2019 Toyota Land Cruiser you will need to start with a 4-way (if you do not have one).

    If you are towing on level ground or rolling hill areas then a proportional brake controller like the Prodigy P3 # 90195 is preferred.
