Brad Hello neighbors, it's Brad here at Etrailer. And today we're taking a look at the Redarc to Tekonsha wiring adapter for your brake controller. The Tow-Pro Elite is a great system, but unfortunately the downside of Redarc is, they don't have a lot of vehicles specific clips, and so you're left with having to tie these into the wiring on the vehicle. I'm not a huge fan of making connections. If there is a plug and play option available, and that's where this comes into play. Now, this plugs into a Tekonsha plug that goes to our factory clip.
So what they did is they've made this little piggyback adapter here that goes from the Tow-Pro Elite module to the Tekonsha wiring that goes to the factory style plug. And Tekonsha has quite a wide variety of different vehicles. So you generally can find something that's specific to the clips on your vehicle to make it nice and easy. And instead of designing their own for each vehicle specific they just use the Tekonsha, and then this little plug goes into that adapter, making it nice and easy and not having to splice wires. So to get this to work for your specific vehicle, you wanna use our fit guide on the website to determine the Tekonsha wire that you'll need for your vehicle, and then you can simply get this adapter to the Tekonsha and you're gonna be good to go.
In conjunction with that Tekonsha wiring, you can see, we we're able to plug into our factory wiring on the vehicle, no tools required. And that was a look at the Redarc to Tekonsha wiring adapter for your Tow Pro..
This is the greatest thing since sliced bread! I was installing a Tow Pro in my 2023 Nissan Pathfinder. Redarc does not make a wiring harness for that model—but Tekonsha does! So I ordered the Tekonsha harness and this one, then chained them together—Pathfinder to Tekonsha harness to this harness to the Tow Pro. Made the installation super simple!
Worked perfectly on my 2024 Sprinter 25 00

Woohoo! Love to hear that, Kenneth. But now the most important question is, what are you going to be towing?
Great controller

The reason for the average rating is shipping. I requested expided shipping as we were leaving on our adventure. If I knew that wasn't available I would have cancled the order and sourced these parts elsewhere. You made your sale and I'm stuck making other arrangements. Your system is not flexable as I tried to change shipping address or pick up in person. All a solid NO.

Worked well, plug and play.
Did exactly what I needed it to do, and it arrived quickly. A little ridiculous that there's no direct adapter to plug the Tow-Pro into my 2024 Subaru Ascent. I have to convert Tow-Pro to Tekonsha, and Tekonsha to Subaru, but it seems to work fine, and that's not etrailer's fault.
The Redarc Tow-Pro Wiring Adapter for Tekonsha Brake Controller Harness made my Redarc install easier.
Was not able to use this adapter due to distance from fuse block to mounting point. Cable could have been 24 inches longer.
Hardest part was trying not to sweat to death in the SC heat. This was super easy to install once I located the receptacle on the car itself.
This is totally not necessary. The Redarc gives you a plug that fits. It follows the same color code as the Tekonsha harness. It will be a simple 2 minute splice job. I will be splicing the harnesses instead of using this. The wires used in the adapter are smaller that those used in either the Redarc or Tekonsha harnesses use. Although it was built fine, it is a waste of money.

Thank you for your review. This Redarc Tow-Pro Wiring Adapter for Tekonsha Brake Controller Harness is designed so that you will not need to splice wires when installing the brake controller.
Excellent job and performance
This brake controller worked well in our 2020 Suburu Ascent. Modified the blank switch plug under the dash to the left of the steering wheel. This took a little time to ream out with a dremel type tool, but the controller know fit in and worked well (youtube videos can be found for this).
This adapter coupled with a Tekonsha Plug-In Wiring Adapter (Item #3062-P) worked as advertised to connect my 2022 Subaru Ascent with the factory tow package to a Redarc Tow-Pro Elite Trailer Brake Controller (Item #RED44FR). Just wish I didn't need the non-Redarc adapter in addition to this to finish the project.
Works as advertised.
Part was exactly what I needed to complete my Redarc brake controller installation.
Works great and doesn't take up much room. Easy installation with great instructions.
This made the brake controller truly plug and play.
Exactly what we were looking for.
Perfect fit! We had the Tekonsha pigtail for the Gladiator but not the plug-and-play connection to the RedArc brake controller. This was it!
Just What I needed to connect my Redarc Tow-Pro to my vehicle.
The 331-TPH-017 connection converter worked as advertised to easily and quickly convert my JT's Mopar connector over to the Redarc connector.
I am sorry to say that I ordered the wrong part. I still want it though. Thanks for the fast shipping as I needed this part for my brake controller. I ordered the part before I left LV, Nev and it sent to Stockton. I expected the part Monday, but it arrived Saturday. But the bummer was the part didn't fit the back of my controller.
Made wiring up the brake controller a whole lot easier.
Was saddened to see that this product was delayed by shipping whether at etrailers facility or with the USPS. It was delayed more than 4 days causing me to purchase from camping world at a higher cost in order to meet my departure schedule. Not a happy customer.
Absolutely excellent! I switched from an app-based assist-brake control to this product. Night and day. From constant worry to being constantly impressed. Thanks!
received adapter with harness wire and installed in 2021 jeep grand Cherokee limited with factory installed tow package. Everything connected.

It's the yeast they could do since they don't have a custom harness for your Pathfinder :)
