Most brake controllers stick out and take up knee room, but this one hides the main unit behind the dash. All you see is a small control knob—just 9/16" wide and less than 2" long—that handles everything. It looks like a factory switch and keeps your cab tidy. Turn it to adjust power or press it for manual override. The LED changes color to show braking strength or system status, so you always know what’s happening.
Uneven ground can make towing unpredictable. The off-road mode gives you direct control over your trailer brakes with preset power independent of your vehicle braking. Set it low for sand or mud so the trailer doesn’t dig in, or higher for steep descents to keep it from pushing forward. A quick double tap on the knob activates the mode, and the green LED confirms it’s ready.
Braking feels natural with proportional control that matches your trailer’s braking force to your tow vehicle’s deceleration. The internal 3-axis accelerometer senses movement in any direction, applying the right amount of brake power every time. It works with electric or electric-over-hydraulic systems on trailers with up to 3 axles (6 brake assemblies), keeping stops smooth and even while reducing wear on both sets of brakes.
Wiring a controller doesn’t have to mean cutting or splicing. The included adapter connects directly to a Tekonsha plug-in harness for a straightforward installation. Mount the compact 4" x 3-3/8" x 1-1/8" main unit anywhere within the reach of its 3' cable, then secure it with screws, tape, or zip ties. A universal mounting panel helps the knob blend in for a factory finish.
Designed for both 12-volt and 24-volt systems, the controller outputs 9V–32V and handles up to 25 amps continuous current at 12V DC maximum charging voltage. It meets UNECE R21 and FMVSS 201 safety standards, ensuring consistent operation under demanding conditions. A 2-year warranty backs its durability and performance wherever you tow.

Next level of brake controller
Wow!! Our horses love it! Braking is so smooth now with our 45’ horse trailer.. wish we had this 10 years ago
Best brake controller I’ve had. Very easy to use and adjust
Excellent - very small so your knees to not hit it.
Looks like a quality product I'm Excited to install in my Toyota Highlander.
Perfect small option. I mounted it to one of the blanks to the left of the steering wheel in our Ascent. It is super easy to reach while driving and keeps with a clean factory look instead of a visible box with led screen.
Part of my 22 Bronco hitch installation process. Installed super easy. I watched the Chase Gentry video on [online] before hand, very helpful.
Just installed it today and the quality of controller looks great:
I purchased it for towing an off road trailer and there manual says that this unit is perfect for it.Etrailer was super fast for shipping. Thank you
I installed this in a 2023 RAM Promaster 2500 159WB van with factory installed hitch. There wasn't much info on how to do this.
Product was delivered as expected. Very good. The reason for only two stars is that the control knob was broken. No LED lighting which apparently causes the whole unit to not function properly if at all. Customer service is supposed to be sending a replacement on emergency status. I hope this is the case as I’m supposed to picking up a new trailer on Tuesday 8/23/22 and a functional break controller is needed. My rating would be much higher had I not had this issue. Hopefully it gets handled right away and I have the replacement by Monday 8/22/22.
Works great, looks good on the dash of the truck. Easy to adjust camper braking.
Installation were breeze, great set up, easy use.
2021 subaru Ascent
This Redarc pro elite looks great in my 23 Subaru ascent; it looks factory. I mounted remote head in front of shifter(very easy to get at)where there was an empty blank.Mounted module to one of column support bracket in spot where it would not interfere with any adjustments of column. By far the longest part was modifying blank with dremel tool to perfectly accept remote head(45 min)(but worth going slowly and taking the tim)This was a completely plug-n-play install.this kit put together by etrailer came with all harnesses so all could be just plugged in; this is why I always use etrailer; I know they have already done the behind the scenes vetting of every product they sell. THANKS ETRAILER
Purchased a 22' R-Pod 192 TT to pull behind my 2019 Benz GLS450 with a factory tow package. It was equipped with the "green brake connector" located by the left kick panel. Contacted etrailer to help choose the correct combination of parts for my vehicle. Was suggested the Redarc EBRH-ACCV3-NA Brake Controller and a TPH-017 Wire Harness. Once products were received, still needed a harness from the green connector to the unit. Wrote to manufacturer in Australia and was told also needed etrailer part number 3066-P. Ordered. Now had everything needed. However, where to mount the switch? One individual with the same Benz mounted it next to the cup holders, but he didn't have a switch for the cold/hot--I did. There was no where else to drill a 1" hole. Got an L-bracket from hardware store and modified it to accommodate the switch. Mounted the main unit securely to the underside of the dash panel and used 3M Dual Lock tape to attach it--no holes to drill. Haven't had an opportunity to tow yet; however, did follow the instructions for the initial "learn" by driving and braking without a trailer attached. Been quite a challenge, but happy with the results and support from manufacturer and etrailer. Happy Camping!
This worked perfect in our 2020 Acura MDX. Love how it looks and operates. I removed the center council (see link to video on how to below) and mounted everything in there.
The control knob looks great and is out of the way. I removed the 12 volt charger port and put the knob in its place. The only catch was it was not easy to find the fuse for the brake controller. After research and trial and error, I found the fuse was #17 in the rear fuse box. I appreciate the great service and support from etrailer.
