Features to know about

Installing a trailer connector can be daunting, but the custom-fit T-One connector makes it a breeze. Just plug it directly into your vehicle's existing wiring system without the need for cutting, splicing, or tapping. It's a straightforward, hassle-free process, even for those with minimal mechanical skills. You'll love how quickly and seamlessly it integrates with your vehicle, saving you time and effort.

Ultimate Convenience: 4-Pole Flat Trailer Connector

It's a universal solution compatible with 5-pole, 6-pole, and 7-pole adapters (sold separately), ensuring versatility for various towing setups. Go from unboxing to fully operational with ease, getting you on the road faster with a reliable connection.

Durability and Longevity: 16-Gauge Bonded Wire Construction

Electrical issues can ruin your towing experience, but the durable 16-gauge bonded wire construction provides robust performance that stands up to the elements. It’s designed to endure tough conditions, ensuring a consistent flow of power to your trailer's lights. Enjoy peace of mind knowing your wiring harness will hold up over time, maintaining excellent functionality.

Clean and Protective Design: Dust Cap Inclusion

Keep your trailer connector free of dirt and debris with the handy dust cap feature. It offers an extra layer of protection when your trailer connector isn't in use, extending the life of your connection by preventing corrosion. This thoughtful design detail ensures your setup is always in optimal condition.

The harness fit perfectly. It took me less than ten minutes to install. It's a quick and easy solution. Goodbye wire splicing!

it was easy to install havent tried it on the trailer



by:

the length of the wires from the 4 pin inline connector to the first spline it is a bit short, 6 more inches would be more "forgiving"; it is manageable.

easy to install (once I removed the upper panel covers to expose the correct harness plugs...)
Also, dont forget to attach the ground

Works great!

Hi
Installed in minutes appears to
be a nice addition to our business for hauling more merchandise. BUT the four smaller flat pieces of steel that hold the bolt head spin inside the 2010 Chevy Express frame and torqueing to speck was not achieved. I was able to wedge 3 of the four plates with bolt to stop it from spinning and torqued to spec but left one middle one un torqued. The light kit will have to be installed when the vehicle is empty to access the panels for removal.

light kit went easy all is well thanks. One thing, keeper pin a little hard to access so far under the bumper but the hitch does its job.

Very easy to install on my 2018 Express 3500 Passenger. Follow this video: https://www.etrailer.com/tv-install-tekonsha-prodigy-p3-trailer-brake-controller-2017-chevrolet-express-van-90195.aspx

I ran the right side light in a channel over the door (see pic of me pointing to it). I used an old tension rod to punch through the gasket and pull the wires through the body... no cords dangling out of my door!

I also installed the Curt Heavy Duty hitch and the 7 wire RV harness (for vans without factory wiring)... all using the video above.

2007 Chevrolet Express Van

If you can't figure out the install on this, then you should'nt be driving. Easy, fast and worth the price. I paired this with the wiring kit for trailer brakes and 7-wire harness and I'm ready to tow. 2007 Chevrolet Express AWD passenger van.

Hi Pete! Just now seeing this review. I looked in to it and it looks like our team is still working with you on this. Thanks for letting us know so we now have a chance to get things straightened out.



by:
2018 GMCSavana Van

Both products were huge disappointment but this one was a total joke. The connectors do plug right in but the wires are too short to cleanly route or hide they have to be hanging in the air to reach - same behind the vehicle. This is worthless unless you just want the plugs, you will have to cut and buy a new flat to extend to your receiver unless you just want it all hanging from the plugs in the way of your cargo.

  • Parts Needed to Install 4-Way/7-Way and Brake Controller 2012 Chevy Express 2500
    Hey David, we can definitely help with that! So the first thing you need is a 4-way like the part # 118392 that is a confirmed fit for your 2012 Chevy Express 2500 and then from there you'd need to convert it to a 7-way with the part # ETBC7 which comes with everything needed to wire in a brake controller as well like the P2 part # 90885. The ETBC7 kit has a 4-way on the side as well so you'll end up with both connectors you are wanting as well.

  • Does Blue Wire of 7-Way Need to be Connected when Using Curt Echo Brake Controller
    Hey John, so since the Curt Echo part # C51180 provides it's own brake output circuit you don't need to connect the blue wire of the 7-way adapter part # 37185 on the vehicle side. Only the black wire needs to be connected. Which we have a version of this adapter with just what you'd need with the part # ETBC7. If you need a 4-way too you'd want the part # 118392 and you'd be set.

  • Recommended 7-Way and Brake Controller on 2019 Chevy Express Van
    For the 2019 Chevy Express Van 2500 without a towing package, you will need the Tekonsha T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector part # 118392 which will give you a 4-pole to start with if you don't already have one. Then you will need a 4-pole upgrade kit part # ETBC7 which comes with all of the components needed to wire in a functional 7-way on your van. I have attached the video and wiring diagram for your reference. It sounds like you may be towing a trailer...

    Hey Scott, thanks for reaching out! The parts you're looking at will definitely get you what you're wanting in terms of wiring and a brake controller on your 2019 Chevy Express 3500, but I actually recommend swapping out the Hopkins Wiring # 31345 with the Tekonsha T-One # 118392. In my experience, Hopkins is less reliable and I wouldn't be surprised if you had to end up changing out that wiring a little further down the road. So for your application I recommend the following parts: ...

  • Brake Controller and Trailer Connector Recommendation for 2009 Chevy Express
    Since your 2009 Express (which was built across the street from our facility) doesn't have a factory 7-way, there isn't a plug and play trailer connector option. That's not the end of the world though, because the installation is pretty simple, and we can help you through it. First, you'll need a 4 pole trailer connector to get the lighting circuits. I'd recommend part # 118392. You'd then choose a brake controller. I'd highly recommend a proportional controller like the Tekonsha Primus,...

  • What Hitch and Wiring Harness Do I Need for Towing an 8000 Pound Camper on a 2007 Chevy Express Van?
    For towing an 8000-pound camper on your 2007 Chevy Express 2500HD, I recommend the etrailer Trailer Hitch Receiver - Custom Fit - Matte Black Finish - Class IV - 2" # e98861. The etrailer hitch has a gross trailer capacity of 10,000 pounds and a maximum tongue capacity of 1,000 pounds. Since you have a 2007 Chevy Express without a towing package, the only plug and play option we carry is a 4-pole connector, but you can convert it to a 7-way.

    Yes, as long as you have a basic understanding of how wiring works and have basic mechanical skills you could install a brake controller in your 2005 Chevy Express Van. Since you do not have a trailer connector you will want to first start with a 4-way. For that you will want part # 118392. Now to convert the 4-way to a 7-way and install a brake controller you will need the part # ETBC7. This comes with everything needed except for the brake controller.

  • Best Hitch for a 2021 Chevrolet Express Cargo Van
    The hitch that I recommend for your 2021 Chevrolet Express Van is the etrailer Trailer Hitch Receiver # e98861. This hitch is made in the USA, has a bolt-on, no drill installation and has plenty of weight capacity to tow a small trailer. It will provide you with a 2" receiver opening that is the most common size used for hitch mounted accessories like bike racks, cargo carriers and ball mounts for trailers. I also recommend picking up the T-One Vehicle Wiring Harness # 118392. The T-One...

In order to complete your setup you'll need wring as well, the T-One Vehicle Wiring Harness part # 118392 would start you off with a 4-way which could then be adapted to a 7-way using the 4 to 7-Way with 4-Way Adapter part # ETBC7.

  • Best Way To Add 5-Flat To 2017 Chevy Express 3500
    Hey Jerry, thanks for reaching out. We do have the parts needed to add a 5-flat connector to your 2017 Chevy Express. What you will need to do is install a 4-flat T-Connector, then install a 5-flat upgrade kit. The 4-flat portion plugs in behind the taillights. For the 5-flat you simply have to tap in to the vehicles reverse light circuit. There are no plug-and-play 5-flat connectors for your vehicle, so this will be the most hassle-free way of adding one.

  • Recommended Wiring Kit for a 2010 Chevy Express to Use a Brake Controller In the Future
    Hey Tim, so to have the capabilities to add a brake controller in the future you'd need to first add a 4-pole with the T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # 118392 and then add the Universal Installation Kit for Trailer Brake Controller # ETBC7. This will add a 7-way at the rear and will allow you to tow a vehicle with brakes, and be able to control them with a brake controller. If you have any other questions, feel free to come back and we'll take care of you.

    For a basic everyday type of hitch the etrailer Trailer Hitch Receiver part # e98861 is the way to go it offers the 2" x 2" receiver tube opening and has a very nice matte finish that looks great. If you're going to be maxing out the Express's towing capacity I recommend the Curt Trailer Hitch Receiver part # C15320 this has the same 2" x 2" receiver tube opening and is best suited on the 2500 and 3500's doing some serious hauling.

    The Draw-Tite Ultra Frame Trailer Hitch Receiver w/ Cast Center - Custom Fit - Class V - 2" # 41946 is a confirmed fit for your 2005 Chevy Express van but the measurements are correct. This hitch does require drilling to install rounding out the holes, so that may account for the difference. My recommendation for you is to use the Curt Trailer Hitch Receiver - Custom Fit - Class IV - 2" # 14090 which measures 40 inches wide on center. This hitch requires no drilling for installation....
