Installation

This custom-fit T-connector plugs into your vehicle's wiring harness, which is located behind the driver's-side and passenger's-side rear access panels. You will have to remove trunk floor coverings, scuff panel, and interior side panel to access this harness. Once you've plugged in the T-connector, run the hot lead up to your car battery. Connect the lead to the included fuse holder, and then connect the fuse holder to the positive terminal on your battery.


Once installation is complete, the 4-way connector will be stowed in an out-of-the-way location within your trunk.


It is recommended that you use a small amount of grease on all electrical connections - the plugs on your automobile and the 4-pole connector itself - to help prevent corrosion.


Powered Tail Light Converter with Surface-Mount Technology

A tail light converter is built into this T-connector. This converter is a circuit-protected, battery-powered unit that bypasses the electrical routes that are used by a basic wiring harness. As a result, there is virtually no draw on your tail light circuits.


Because most trailers run on a two-wire system - wherein the brake and turn signals are carried on one wire - the separate brake and turn signals from your vehicle's three-wire system need to be combined so they are compatible with the wiring system of the trailer. This converter combines the brake and turn signal functions of your automobile so that they run on one wire to properly activate your trailer's tail lights. Note: This will not affect how the tail lights on your vehicle operate.


Curt builds each tail light converter using surface-mount technology (SMT). This method of construction involves soldering electronic components directly to the surface of a printed circuit board. SMT eliminates the need for leads, which are used in older through-hole technology. The result is a circuit board that is smaller yet provides more routing area and that offers superior performance, reliability and durability.


Curt SMT Circuit Boards

Circuit boards constructed using SMT have been shown to perform better under rough conditions with excessive vibration than those made using the through-hole method. And where would vibration be more likely to occur than in towing applications? Curt converters also produce less heat, leading to increased durability and longer life. In addition, lower levels of resistance ensure better performance, especially for parts that operate at higher frequencies.


Each Curt circuit board is made using high-quality components that are pieced together in the most technologically savvy fashion, leading to greater predictability and reliability in functioning.

Video Transcript for Review of Curt Custom Fit Vehicle Wiring - Volkswagen Atlas Trailer Hitch Wiring - C67WR

Hi there. I'm Michael with etrailer.com. Today, we're going to take a quick look at this Curt T-Connector Vehicle Wiring Harness. This wiring harness is designed specifically for your 2020 and 2021 Volkswagen Atlas Cross Sport. It will also work with the 2021 Volkswagen Atlas that is not the Cross Sport. So if you have any of those kinds of vehicles, this is going to be a great option for you to add a 4-pole flat trailer connector onto your vehicle, so that you can hook up for trailer's lights.

This is gonna be compatible with 5-pole, 6-pole and 7-pole adapters. So if your trailer has a 5-pole, 6-pole or 7-pole, you can adapt this to that, so that your trailer lights will work with your vehicle. Those adapters are sold separately, but we do have them available here at etrailer.com for you. So this is gonna be a really simple way of getting that light signal from your vehicle back to your trailer's lights, rather than having to cut in to your vehicle's existing wiring, which could void your warranty. This is going to utilize the plugs on your vehicle.

So you'll just get in to your light housing area, unplug your current wiring, plug this in place. It's gonna have the exact same kinds of connectors here. So it's very easy to plug those in. And then that's going to send the signal through this box here, out to your trailer, so that your brake, running lights, turn signals are all gonna work properly for you. So the red and yellow wire here is gonna be your driver's side, which is where this box is gonna be mounted.

And then this green side is going to run over to your passenger side. Same process there, just get back to your white connectors, pull them apart and then put these in line there. It's gonna recomplete that circuit. So your lights will function like normal, when they're not connected. And then when you are connected, they're still going to function, but it's going to send that signal out to your trailer.

They do provide a ground wire with a ring terminal there. And a self-tapping screw for you to get that mounted to a metal surface. And then this black wire is gonna be your power wire. So you're gonna have to run this up to your battery. They do include an extension to run that up. When you're running this, you do want to make sure you're staying away from anything that's gonna be hot, removing that could damage that wire, but you'll run that up. It does just take a little bit of wiring to strip that wire there. They do include some butt connectors to make that connection. Then up at the front, and once you get to your battery, you'll snip this wire here. This is your fuse holder. You'll wire that in, and they also include a ring terminal for you to then connect to your positive post on your battery and then put your fuse in place. So everything that you're gonna need to get this mounted, put in place is included. The reason that you run that wire, so that you're not putting extra strain on your vehicle's light signals and wiring. So you're providing that extra source of power to make that jump out to your trailer. But it is gonna be a very simple process and just doing a couple crimps to make sure that the wire is connected. You're not gonna have to worry about cutting your vehicle's wiring. It's all this aftermarket stuff. So it's not going to damage your vehicle at all. And they do include some very detailed instructions to walk you through that process. Step-by-step and much more detailed than I just went through, but it is gonna be a great way to make sure that your trailer's lights are functioning properly. And this box is gonna convert your vehicle's lights to work with your trailer's lights, gonna combine them onto the same signal that your trailer's lights will recognize. It will provide 5 amps per circuit for your stop and turn lights and 7.5 amps per circuit for your tail lights. This does also include a dust connector or a dust cap here to cover those connectors. The wiring coupler will be stored in your vehicle until you're ready to use it. And you can just pull it out, close the back hatch on it, just to make sure that it's not gonna be pinched with that connector that's gonna latch in place. Any other part of your back hatch, this will fit in there. Won't be damaged at all. You'll be able to run this out, connect it to your trailer, and then be ready to go. So really nice system here, definitely something that you can install yourself. You don't need to pay someone else to do. I installed a very similar system to this in my wife's vehicle, not too long ago. Didn't take me very long at all. One of the hardest parts for me was just trying to pry those plugs apart, just 'cause sometimes it's in a hard to reach area and trying to get those little prongs to come apart. It was a little bit difficult and then running that wire is gonna be a little time consuming, but it shouldn't be too hard for you. They do include some ties there to get everything up and out of the way. So definitely a, a project that you can do on the weekend. If you're getting ready to do, do some towing, you want to make sure that those lights are gonna work for your vehicle. This is going to be a great kit for you. So that's going to complete our look for today. Again, I'm Michael with etrailer.com. Thanks for watching..

Quickly and easily install a 4-way trailer connector on your vehicle with this custom harness. T-connector plugs directly into existing wiring. Powered converter reduces strain on wiring system and is made using SMT to ensure superior performance.

Product is good but install is not really plug and play. Be ready to run a wire from the battery through the firewall under the car to the rear tail light area. Install is not as quick as you think it will be when you order. But after all is said and done it works well and quality is good.

Volkswagen

After installing 2 Tekonsha T-One connectors without brake light functions, this controller was a godsend. Works exactly as it should on 2021.5 VW Atlas. Brake, running lights and turn signals all work correctly with this connector without having to modify the OEM wire harness. This system is plug and play with the most difficult part being routing the independent power to the battery above the intricate plastic protector plates underneath the car.




by:

This harness is the one to use for a 2021 Atlas. Works perfectly and is simple to fit. Running the live wire under the car from back to front sounds daunting but in reality is a simple task. The plugs into the lights is very easy and takes only two minutes. Overall a great easy product.

See what our Experts say about this CURT Custom Fit Vehicle Wiring

  • Can Power Port on 2022 Volkswagen Atlas be Used to Install Curt Trailer Wiring Harness
    That's a pretty common question as it is simpler than running the 12 volt hot lead to your battery, but you cannot use the drivers side cargo area power port on your 2022 Volkswagen Atlas to install the Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # C67WR. The reason why is this is the only way to ensure your VW's wiring is not otherwise affected (by tapping into it) and that you have consistent 12 volt power.

  • Vehicle Wiring Harness For a 2021.5 Volkswagen Atlas
    Yes, the Curt T-Connector Vehicle Wiring Harness # C67WR is the correct harness for your 2021.5 Volkswagen Atlas. This harness works for both the Cross Sport and non Cross Sport models. The wiring harness is designed to be stored inside the rear cargo area and ran outside the vehicle across the rear hatch seal when needed. The Curt Easy Mount Bracket # C58002 can be utilized if you would rather run the wiring outside the vehicle and secure it to your receiver.

  • Hitch and Trailer Wiring that Fits 2022 Volkswagen Atlas Cross Sport
    For the 2022 Volkswagen Atlas Cross Sport we have the Curt hitch # C93CR as a confirmed fit and for wiring the part # C67WR. This trailer wiring harness does store in the trunk when not in use and then when needed you'd pull it out of the trunk and then shut it on top of the harness. I know this would seem like it might damage the wiring but the weather-stripping is so thick that basically it just gets squeezed by a thick rubber seal and the wiring does not get damaged in any way.

  • Recommended Trailer Hitch And Wiring To Tow A Trailer With A 2022 VW Atlas
    We definitely have what you need to get your 2022 Volkswagen Atlas all set up to tow a small trailer. There will be a couple more things needed than just a hitch and wiring, but not many.
