Video Transcript for Redarc Tow-Pro Trailer Brake Controller Plug-and-Play Wiring Harness Review

Brad Hello neighbors. It's Brad here at etrailer. And today we're taking a look at the vehicle-specific wiring harness, that will work in conjunction with the Tow-Pro Elite electric trailer brake controller. These harnesses are going to be great to work with your Tow-Pro Elite in a variety of different trucks and SUVs. Now, make sure that you get your vehicle-specific harness. You're going to want to use our fit guide on "etrailer.com", and that's going to make sure that you get the right harness, and that way your install goes nice and easy.

Included in the REDARC kit, you will find this plugin adapter, and this is going to have these spliced ends, and you're gonna have to tie into your brake signal, your brake output, your power output and your ground. Now, if you are pretty handy with electrical, that's awesome. That's great. You can use this. But I'm the kind of person, plug and play in OEM kind of setup or really nice factory one like this.

This is the vehicle-specific harness. So this ties in directly to our factory tow system, and clips right in, it's got this nice braided sheathing on it, to kind of protect the wires, and then it plugs directly into our module here. So, to save yourself a little bit of headache and time, and make the install go that much smoother, and not have to worry about loose connections, I highly recommend getting the vehicle-specific harness. So this end of the plug is specific to your vehicle. As you can tell, it looks like the factory plug, it fits in perfect, has the locking mechanism, so you aren't gonna have to worry about loose connections happening with your plug, and it's going to make install a lot easier.

And that was a look at the vehicle-specific harness for the Tow-Pro Elite electric trailer brake controller..

Clean install. I really like these Redarc controllers. 2021 Nissan NV 3500 Passenger. etrailer kit with controller and wiring adaptor was just the thing. Under dash drill access for mounting the module isn’t ideal, but doable. Great kit and great price. Looks great

So glad etrailer had this part. Made the installation so simple and quick! Saved me a LOT of time, effort, and stress. Absolutely worth it! Their customer service is above par!

One year in and only have use the controller a few times camping. Installed on a 2022 Nissan Frontier Pro4X. Really like the way the brake controller worked. Easy to install and set up and very adaptable to changing conditions. I had a problem with my truck battery dying and realized that the Redarc brake controler was causing a parasitic draw so it had to be disconnected. The truck was brand new and the issue resolved as soon as the controller was disconected. I wrote a letter to etrailer explaining the issue however they did not offer any solution for me so I am stuck with a controller that may not be usable. Going camping for first outing this year in a couple of weeks so I will hook it back up and see if the problem returns. So I would rate excellent for how it works but poor for the issue it caused. For now I would have to be generous and give an average rating all things considered. I was disappointed that eteailer didn't offer a replacement. I will be camping with an extra battery on board just in case.

I want you to be able to use the controller with confidence and without draining the battery. I reached out to RedArc about the battery problem that you have been having with the controller. They had additional questions to ask about the controller with performing a few more current draw tests. Would you be able to use a multimeter to measure the current-draw through the Black wire to the unit? This would help to show if the TowPro is using more power than it should be. If it is then it can definitely be replaced under warranty, They also wanted to see if you could grab the serial number from the side of the main unit. With this information we can get you taken care of.

@Richard Great to hear. Thank you for the update.

The install was straight forward. Being my second time I was able to install the controller easily and without much complication. I have both a Nissa Pathfinder and Armada, which made the installation easier since both models are similar. The product responds well, still trying to dial in the perfect breaking level.

I have ordered from
etrailer twice and both times I received exactly what I needed and the installations were easy!!!

Excellent unit, work as advertised. Plug and play and excellent results. I was able to place the unit behind the console so only see the controller knob.

2021 Nissan Frontier

Installed in my 2021 Frontier. There is a round knock-out plug where the ignition/key fits on previous models, so it was easy to mount the switch there. Fastened the controller to the sidewall under the dash, behind and to the left of the diagnostic port. A couple of zip ties and done. The hardest part was drilling holes for the control knob.



by:
Nissan Frontier

Fits as should in the 2023 Nissan Frontier. If you have the factory tow package the plug is on the far left under the dash easy to get to.



by:

Put it on a camper and it is doing its job..

This is required and vehicle specific for the Redarc Tow-Pro Trailer Controller. Follow the instructions and everything fits and works as it should. Helped to view instructional Video on etrailer website at time of ordering

The led light doesnt shine through very brightly as I adapted one of the spare knockout plates to mount the control knob. Regardless the controler is doing what its supposed to do.

Exactly what i was looking for, discreet, not a box hanging from the dash.

Worked great, still works as expected



by:

E-trailer needs to include the knockout holder for the knob in the standard offering for the Frontier. Most of the time spent installing was carving on the factory supplied blank. I would have gladly paid for the click-in holder which I thought came with the custom plug-and-play harness. Otherwise, it was super easy, thanks to Nissan supplying the harness connections. The panel removal was easy enough with just one screw to remove.

It looks like you ordered the Redarc Tow-Pro Liberty part # RED24FR. The mounting panel that you would need is a universal fit part # RED37FR which does not come with the brake controller or wiring.

  • Recommended Brake Controller to 2024 Nissan Frontier With Tow Package
    For your 2024 Nissan Frontier I recommend the Redarc Tow-Pro Liberty Brake Controller # RED24FR. I like the Liberty because it is simple, reliable, and looks great in any vehicle. The main unit installs behind the dash, so only the control knob will be visible. The knob controls the braking power and acts as the manual override. It also uses colored LED lights for diagnostics. The # RED39FR wiring harness will plug into the port under the dash you referenced for a plug and play installation.

  • Complete Tow Package for 2020 Honda Pilot to Tow 5,000 Camper with Brakes, Hitch, Wiring, Ball Mount
    Hello Lewis, I can definitely get you set up with the correct towing components to get you out on the road to adventure! You’ll want to check your owner’s manual to see what Honda says you can tow, just because the hitches are rated that high doesn’t mean you should be towing that much weight. - Hitch: Just as long as your camper is no more than 5,000 pounds, a Class IV isn’t necessary. I would go with our etrailer Trailer Hitch Receiver - Custom Fit Class III - 2" # e44AR. I really...

  • Troubleshooting a Redarc Tow Pro Liberty that Isn't Turning On A 2019 Infiniti QX80
    Hey Josh, since you're using a plug and play harness # RED39FR there shouldn't be a whole lot of riff raff to use it so the only thing I can think of is that either you have a faulty harness or that there is a blown fuse somewhere that needs to be replaced. You'd need to consult your owner's manual for a fuse diagram and look for anything relating to towing and check the fuses. There's also a chance that the fuse itself was never put in, so I'd keep my eye out for that as well.

    I would recommend the Strait Line weight distribution system part # RP66083 which has a tongue weight range of 400-800 lbs and features only sway control that works to prevent sway before it starts. For a brake controller I really like the Redarc Tow Pro Liberty part # RED24FR which only puts a small knob on your dash instead of a big controller box and is proportional instead of time based. To install it in your 2020 Nissan NV 2500 would only require the install harness part # RED39FR...

    Yes, per the installation instructions, your 2014 Nissan Pathfinder with the Controller Area Network, or CAN Bus system, it is recommended by the manufacturer that you use the 30-amp circuit breaker kit # 331-CBK30-EB. This, along with your Redarc Tow-Pro Liberty Brake Controller, # RED24FR and the Plug-and-Play Wiring Harness for Redarc Tow-Pro Trailer Brake Controllers, # RED39FR (TPH-014) will have you all set.

    First lets start with a hitch for your 2022 Nissan Frontier. For that I'd recommend the etrailer part # e98869 which has great towing capacities and is mostly hidden. Then for trailer wiring you would need to start with the 7-way kit part # 118266 which comes with brake controller wiring. Then for a brake controller I would recommend the Redarc Tow Pro Liberty part # RED24FR which only puts a small button on your dash instead of a large box like traditional controllers. Then to connect...

  • Recommended Brake Controller and Plug In Adapter for a 2017 Nissan Titan
    Congrats on the new truck! You've got the right parts entered and that is all you will need. Our fitguide is fun when it comes to Redarc Controllers. The fit is determined by the wiring harness on those. None of the individual units say they fit any vehicle which is frustrating and confusing to everyone. For your 2017 Nissan Titan you will need the Redarc Tow-Pro Liberty Brake Controller item # RED24FR you were looking at and the Plug-and-Play Wiring Harness item # RED39FR you referenced.

    The Pigtail # RED39FR that you received with your Redarc Tow-Pro Liberty # RED24FR should match the functions on the OEM plug of both your 2006 Nissan Xterra and your 2022 Nissan Frontier. If the pins aren't matching up with the functions then either the wiring adapter you have was wired incorrectly, or your vehicle wasn't wired correctly. Some other things to look into is making sure the wiring isn't damaged anywhere and causing the functions to cross over either in the connector or on...

  • Parts Needed for 2023 Nissan Frontier to Tow Trailer With Brakes
    Towing a trailer with brakes will require adding a 7-way along with a brake controller. Since you were already looking at 4-way wiring I'm assuming there is no factory trailer connector on his 2023 Nissan Frontier. All you will need to add a 7-way is the Curt T-Connector Vehicle Wiring Harness # C56226. The brakes and the lights aren't tied to the same wires but the 7-way will take care of powering all your lights along with sending power to the brakes. For a brake controller, I recommend...

    Yes, your 12 volt charge line should be functioning with the T-One Vehicle Wiring Harness # 118273 on your 2019 Nissan Pathfinder. I first recommend checking your fuses and relays as I have often seen some of these components not included from the factory when a vehicle like your Pathfinder does not include a tow package. I was unable to find a good list of the fuses and relays online so you will need to check your covers for the location of the different components. Next you will want...

I have attached an installation video below along with the instructions so you can see how to get it set up. To add a 7-way connector, I recommend the T-One Vehicle Wiring Harness item # 118273.

  • Will the Redarc Tow Pro Plug and Play Wiring Harness Work With the Canadian Nissan Frontier
    According to Nissan, the only real difference between the Canadian Frontier and the American Frontier is the shift on the fly 4 wheel drive system with 2WD/4Hl/4LO models, which won't affect whether the Plug-and-Play Wiring Harness for Redarc Tow-Pro Trailer Brake Controllers # RED39FR will work with your truck or not. So yes, this wiring harness will work just fine with your Frontier.

    To add a hitch to your 2023 Nissan Frontier you are going to want the Curt Trailer Hitch item # 13241. This hitch is custom fit and bolts to your Frontier with included hardware. I really like the Curt hitch because it installs behind your rear bumper and the crossbar is completely hidden. This is a class III hitch with a 2" receiver. It has a 5,000 lbs towing capacity, and a 500 lbs maximum tongue weight. This towing capacity and tongue weight can be increased to 8,000 lbs and 800 lbs...

  • Difference Between Redarc Tow-Pro Elite & Tow-Pro Liberty For 2022 Nissan Frontier
    The biggest difference between the two Redarc brake controllers is that the Tow-Pro Elite # RED44FR has a proportional control and user controlled mode you can switch between, while the Tow-Pro Liberty # RED24FR has just the proportional mode. The proportional mode is for everyday, normal towing - your trailer brakes will activate at the intensity which you decelerate, and gives them the appropriate power for that deceleration. User controlled mode applies the same amount of braking power...

    Hi Alvin, You'll need to disconnect the 4-pole trailer connector that you have installed and replace it with the T-One Vehicle Wiring Harness with 7-Way Trailer Connector # 118266. This kit includes everything you'll need for a functioning 7-way, including some relays that you'll need to install in order to get power to the 7-way. It won't come with a mounting bracket so I recommend picking up the no-drill bracket # 18136 and mounting it to the trailer hitch. From there you'll need to...

This is a plug-and-play harness, that will plug underneath the dash on your 2022 Frontier like you had mentioned.

That is behind the side panel by the OBD connector and is likely pushed back into the cavity taped to other wiring. Sometimes it can be difficult to spot because of the tape.
