Used on a 2021 Ford Ranger XLT - Camping World installed the wiring and removed the guts of the left side 12v plug that wasn't being used. We did have to order this panel and I had it sent to my home instead of going back for Camping World to install. I only had to make a little notch at the top of the open hole where the 12v plug guts were removed so that it would fit- literally used my bare hacksaw blade and made about 3 little bitty notches and knocked out with a screwdriver and it slipped right in and snug.



by:

This mounting piece is awesome, everything snaps into place very well and it feels and looks like it came with the truck from OEM.

Man, it really does! Great job on that install because it really took me a second to find it in the picture. Seamless!



by:

Saved about 200.00 using this with the Tow-Pro by RedArc over using this OEM trailer controller. Set ups easy (hardest part is removing the 12v battery supply), nothing a screwdriver and snips can't fix. Install took less then 30 minutes using the TPH - 022 harness for the Gladiator. Looks very professional.

Looks like it was an OEM product. Easy install. Working perfectly.



by:

Had to cut off the locator tab and file down a little bit to install with the letters and light hole up in the Gladiator. It did snap on well however doesn't exactly fit flush without some slight modifications and a shim I used that was on the original cigarette lighter. Looks great now and close to factory.



by:

Made Redarc brake controller installation into one of the power ports (fka, cigarette lighters spots) easy and looks like original equipment.



by:

It fit perfect
Just to be sure it wouldn't
spin i used a little silicone on the edge.



by:

Shipping said 4 days to get here.
3
days later they finally shipped part.
By then I had allready ordered from another company got it to me in just over 2 days. The part finally arrived today. 4 days to late.



by:

Etrailer.com is a great company! Friendly and knowledgeable staff.
This product fit perfectly and looks great in my 2025 Frontier.



by:

Great alternative to the square plate provided, particularly because of where I’m mounting my switch.

@Shane That's great! What vehicle are you using it on?


by:

I bought the redarc controller for my 2023 Ranger from Ford but this adapter from etrailer. There is a bunch of video online for installing it and it went in without a hitch. Works great.



by:

This snapped right into the 12v outlet hole in the dash panel of a 2021 Ford Ranger! Much nicer than drilling anything. Puts the knob in a perfect spot for quick engagement and visual of the LED indicator.



by:

Looks and works better than the one that came with the brake controller



by:

Good day after a couple tries the round mounting plate was my best option I was replacing the dash insert with the electronic OEM brake controller plate that I found out would not work because my truck didn't have the RCM program so I bought the radic brake controller I took apart the OEM brake controller to get a piece of the plastic to make a plate then I cut out the OEM Dash plate to accept the piece of plastic and then cut that out to accept the round mounting plate ran all the wires everything works I'm going to attach a couple pictures or a few pictures to show what I did there is no direct replacement mounting plate for the small storage box on the OEM plate that was in there or replacing the OEM electric brake module there was no plate to fill that in so I made one myself probably not the finest work because I am very seeing impaired but you'll see in the pictures this is what it looks like thanks again everybody at the trailer for all your help and Jamie and I will attach the pictures



by:

Used on a 2019 Ford Ranger, and it worked great.



by:

It was rather hard to get the 12v port out but otherwise install eas very easy especially with your great step by step youtube video.



by:

ETrailer delivered over night by noon and I had my install completed in minutes.



by:

The Redarc works great, the only down-side is the button didn't fit my 2021 toyota and I had to buy a different one in order to engineer it it fit. I complained and etrailer paid the shipping. A correctly sized part from Redarc would have been appreciated. Instructions and product worked great.



by:

Needed a trim piece for my '94 Dodge Ram 1500. I knew this wasn't an exact fit but with a little Dremel work and a hot glue gun I think it turned out looking pretty good. I replaced the lower cigarette lighter with the trailer brake controller switch.



by:

Worked correctly but the white dot indicator is located at 9 o'clock instead of at the top



by:

Mounted firmly in place, no movement after mounting.



by:

Fits perfectly in 2022 12v outlet. This is something that should come included in Redarc's controller packages though being that it is so inexpensive for them.



by:

Works perfectly in the 2020 ford ranger. It is a tight fit but does work



by:

Looks stock in a Ford Ranger. Ford should use these if you buy the “factory” brake controller instead of the spot they install it above he hood release.



by:

Product worked great for my 2020 Ranger. It mounted perfectly under the dash and put the controller in the spare 12V socket. Looks good.



by:

Bought this to mount in my 2020 Ranger as shown in the etrailer Redarc install video! Worked as described!
Thanks for pointing out a great alternative install location!

  • 2001 Airstream Land Yacht 395XL Brake Controller Recommendation
    Hey Allen, thanks for reaching out! I really like the Redarc Tow-Pro Liberty Brake Controller w/ Universal Wiring Harness # RED52VR because it can be hidden behind your dash so you're only adding a small control knob to your driving console as opposed to a whole "brick" like what traditional brake controllers look like. If you're a sucker for aesthetics (like I am), I also recommend picking up the Mounting Panel # 331-TPSI-003 for a really clean and factory-looking installation. One...

  • Differences Between Redarc RED44FR Tow Pro Elite and RED24FR Liberty Brake Controllers
    The Redarc Tow-Pro Liberty Brake Controller part # RED24FR and the Redarc Tow-Pro Elite Trailer Brake Controller part # RED44FR have two primary differences. The Elite can toggle between a user controlled (time delayed) mode for the trailer brakes for off road use and proportional mode, while the Liberty operates only proportionally. The Elite is rated for up to 3 axles whereas the Liberty is rated for up to 2 axles. If you won't be operating your trailer off-road, the # RED24FR Redarc...

  • Installing The Redarc Trailer Brake Controller # RED44FR On A 2020 Ford Ranger
    First you'll need a 7-way connection to install the Redarc # RED44FR and we luckily have an installation video of the Curt T-Connector Vehicle Wiring Harness with 7-Way Trailer Connector # C56431 being installed on a 2020 Ford Ranger available and I have attached it for you below. In the video you can see Ryan easily attaches the custom-fit T-connector plugs into the vehicle's wiring harness, which is located behind the driver side rear bumper. Now that you have a 7-way connection port...

  • Recommended Mounting Location For A Redarc Tow-Pro Elite In A 2022 Chevy Silverado 1500
    The easiest location to mount your Redarc Tow-Pro Elite Trailer Brake Controller - 2 Braking Modes - 1 to 3 Axles - Proportional # RED44FR in your 2022 Chevy Silverado 1500 is going to be just below/next to the ignition, as pictured below. This panel can be be easily removed to allow you to create the mounting hole for your Redarc's control knob. You can use either the # 331-TPSI-001 or # 331-TPSI-003 mounting panels for a nice clean look. I've attached a video below where Ryan will walk...

  • Wire Location for Installing Redarc Tow-Pro Elite Brake controller to 2022 Ford Ranger W/ OEM 7-Way
    Yes, the Redarc Tow-Pro Elite Trailer Brake Controller # RED44FR can be installed on your 2022 Ford Ranger. There will be 4 wires sticking out the of large mix of wires coming through the firewall behind your brake pedal. These all have shrink tubing on the ends and carry the functions needed to install the Tow-Pro Elite. We actually had the chance to do this same install on a 2019 Ranger that I'm linking for you to check out. When we did this install we used the Mounting Panel # 331-TPSI-003...

  • Does Redarc Tow-Pro Liberty Brake Controller Fit 2021 Ford Ranger
    The Redarc # RED24FR Tow-Pro Liberty will indeed work just fine with your 2022 Ford Ranger, because brake controllers aren't a vehicle specific piece of equipment. In addition to the controller itself, you'll also need the wiring pigtail, part # RED69FR. The pigtail will wire up with the tow package wiring located under the dash to the left of the steering column as shown in the provided photo and linked video. The tow package wiring consists of a yellow wire with an orange stripe, a blue...

  • Where to Mount Redarc Tow-Pro Elite Brake Controller on 2020 Chevy Silverado 1500
    The Redarc Tow-Pro Elite Trailer Brake Controller # RED44FR, 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 the dash...

  • Recommended Brake Controller For An Itasca Ellipse Class A Motorhome
    I have two recommendations depending on if you plan to flat tow with your motorhome. If you do then I recommend getting the Brake Buddy Stealth Supplemental Braking System # HM39530 as it comes with a brake controller that will allow you to flat tow a vehicle or tow a trailer all in one package. If you plan on only towing trailers with your motorhome then I recommend the Redarc Tow-Pro Liberty Brake Controller w/ Universal Wiring Harness # RED52VR. This brake controller has such a small...

  • Dimensions for Drill Hole to Install Mounting Panel for Redarc Tow-Pro Elite Brake Controller Knob
    The outer diameter of the smallest round part of # 331-TPSI-003 is 1-1/16 inches. That's not counting the tabs or the beveled section and is shown by the red arrow. I think that's what you're asking about. If not let me know. With that being said at the top of that is a notch that makes it so the hole you drill may need to be larger. From top to bottom with the notch it measures 1-1/8, just like the tabs, and is shown with the yellow arrow.

  • Will The Redarc Tow-Pro Elite Require Deactivation Of any Safety Systems On a 2021 Ford Ranger?
    You will not have to turn off any safety systems on your 2021 Ford Ranger Lariat to be able to use the Redarc Tow-Pro Elite Trailer Brake Controller # RED44FR. I verified with your owners manual that there are no special steps required for towing with an electric brake controller. It is likely that what you read was in reference to any forward collision system your Ranger has not activating the trailer brakes when the computer activates the brakes. This is due to the computer activating...

  • 2021 Ford Ranger With Automatic Emergency Braking Brake Controller
    The Kit in the Ford Accessories Store will be exclusive to Ford. None of the other components you mentioned are available elsewhere. You can still install the Redarc Tow-Pro Elite Trailer Brake Controller # RED44FR on your 2021 Ford Ranger. Their kit takes into consideration that when the emergency braking system is activated the pedal is not being pressed by the driver. Hence the trailer brakes without their kit will not be activated until the driver does push on the brake pedal. The...

  • Can Redarc Tow-Pro Elite # RED44FR Be Installed In a 2020 Ford Ranger W/ Factory 7-way Connector?
    The Redarc Tow-Pro Elite Trailer Brake Controller # RED44FR you were looking at is a great choice for your 2020 Ford Ranger Lariat. Since your Ranger has the factory 7-way connector the wires needed to install the trailer brake controller is located underneath the dash just below the main wiring grommet, and will install the same way as the video of the 2019 Ranger you mentioned. When we did this install on the 2019 Ranger we used the Mounting Panel for Redarc Tow-Pro Trailer Brake Controller...

  • Recommended Brake Controller for a 2021 Ford Ranger
    Welcome back and congrats on the new truck! The best Redarc brake controller for your 2021 Ford Ranger is going to be the Tow-Pro Liberty item # RED24FR. This is a proportional brake controller that automatically adjusts your trailer's braking based on the deceleration of your Ranger. The Liberty has a unique installation method where the main unit is concealed behind your dash and the only part visible is the control knob. This means no bulky brake controller to bang your knee on when...

  • Compatibility of Redarc Tow-Pro Liberty Brake Controller With 2019 Ford Ranger
    The Redarc Tow-Pro Liberty, part # RED24FR is compatible, and would be an excellent choice for your 2019 Ford Ranger. As you mentioned, the Ranger has blunt-ended wires for the tow package connection under the dash to the left of the steering column, and you'll need the Redarc # RED69FR wiring pigtail to connect the controller unit to the tow package wiring. The pigtail would connect to the tow package wiring as outlined in the linked video, but I'll provide the wire color code match-up...

  • Is There a Minimum Panel Thickness When Installing Mounting Panel for Redarc Tow-Pro
    Standard interior panel thicknesses will work great with the Mounting Panel for Redarc Tow-Pro Elite Trailer Brake Controller Control Knob # 331-TPSI-003. The panel you are planning to install this on I am sure is totally fine since it was designed for holding the integrated controller of the 2015 Chevy Silverado.

When we did this install on the 2019 Ranger we used the Mounting Panel for Redarc Tow-Pro Trailer Brake Controller Control Knob # 331-TPSI-003 to mount the # RED44FR which replaced one of the factory 12v outlets, but you can mount...

  • Does Mounting Panel # 331-TPSI-003 Install in a Specific Place on a 2016 GMC Canyon
    Mounting Panel # 331-TPSI-003 basically is more of a match to the interior aesthetic of the 2016 GMC Canyon than the standard rectangular panel that comes with the Redarc brake controllers. Since there isn't much space on the right side of the steering wheel it looks like the best location is to the left of the steering wheel in between the steering column and those 2 round knobs on the dash.

  • Where to Mount the Tow-Pro Elite # RED44FR on a 2017 Chevrolet Silverado 1500
    The great thing about the Tow-Pro Elite # RED44FR 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 mounting...
