Quickly and easily install a 4-way trailer connector on your Chevrolet Express Van with this custom harness. T-connector plugs directly into existing wiring. Powered converter reduces strain on wiring system.
Features:
Specs:
This custom-fit T-connector plugs into your vehicle's wiring harness, which is located in your rear cargo area, on the driver's side and passenger's side. Once you've plugged in the connector, run the red hot lead up to your car battery. Connect 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 your rear cargo area.
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.
A tail light converter is built into this T-connector. This converter is a 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.

Havent installed yet but quick shipping
easy to connect, good instructions
Great product and easy installation which quickly resolved my towing requirements! Great customer service!!!
Exact fits for each vehicle make them a snap to install.
Get yours at E-trailer!
The instructions were easy to follow. I wish I had known about the battery terminal adapter--it would have saved me alot of frustration. My fault for not watching the installation video first. Overall, very happy with how easy it was to connect the connectors to the taillight plugs in the back of the van.
Product was exactly as described. I installed this on a 2012 Express 12 passenger van. Although the installation video was for the cargo van, it was extremely helpful. For the passenger van you will need to remove 5 panels, and the rear speaker housing (if you choose to follow the factory wiring). It is easily done and does not require any special tools. The OEM connectors were an exact fit, the wiring bundle to the 4-pole connector could have been about 6" longer and the ground wire could have been about 12" shorter (I cut the ground and crimped a terminal ring), but it did do the job. Total installation time for me was about 90 minutes. overall great product.
These allowed us to set one of our trucks up to tow safely and properly. Excellent quality and customer service.
Super easy to install! I wish they had this kid with a 7 pin.
Great product
Great customer service
The power wire was 10'short. The trailer running lights come on anytime the van is running. The right brake light and running light works in reverse.
This wiring harness was awesome to install. it fit my van perfectly and went together without any problems. I watched the install video and it showed how to route the wiring and that you would need to add wire to part of the harness. I didn't like the way they ran the wiring in the video, so I did it my own way. The outcome was clean and I didn't need to add any wire. Everything reached where it needed to go just fine. Tested the harness and all works great. Thank You for the great product!

Still using this harness every day. it has held up very well
Trailer light kit was a Perfect fit, and the lights work more brightly than just tapping into existing lines. Safer to my system too! The You Tube install video was a big help

Still works perfectly, and etrailer has thoughtful customer service
Easy installation. Year later no issue
Doesn't work. What is wrong with providing actual wiring harnesses for vehicles. I took the the harness provided out tossed it in a box and there it lays.

Would you be able to provide some more detail as to how this isnt working for you?
Overall a great kit, but a couple issues that if corrected, would make it near perfect. The first issue is the area of the mounting bracket for the 4-pole connecter. It is open on one side so that the connector slides in easily... which means it also slides out easily. The bracket needs a redesign to hold the 4-pole more securely. The other issue is the hole on the large ring connectors is too small. I have the extended post battery connectors suggested in the install videos, but the large ring connectors do not fit over the post. I used a step drill bit to open them up a bit so that they would fit, but the large ring connectors in the kit should be changed for ones that are slightly larger to fit the battery posts. Aside from those issues, it's a great kit!
Wires are too short. The length of the 4-wire plug to the trailer is at least 14" too short to reach the center of the hitch and you're limited by the plug into the driver's side taillight connection. The main power lead was about 4' short by my routing through the inside of the van, it probably needs about 6' of additional length to make sure it fits everyone. It took me a couple hours to go get longer wires and solder the connections in place to make this work.
If you need this thing then you are already unhappy because your vehicle wasn't pre-wired for the trailer connection. This adapter makes it reasonably easy to do the wiring, and also by bringing a battery feed wire to this, it doesn't put any significant additional load on the existing wiring, which could be problematic on new vehicles.
Installed in 2012 Chevy Express 3500 van.
The plugs were an exact fit.
The green wire that runs between the two sides of the vehicle was just long enough, but I would have preferred another foot longer.
The wire on the 4 blade connector was NOT long enough. I was only about half the length required.
The red 10 gauge power wire that comes with the kit will probably work for most trucks, however it was not long enough for my van.
You only get a 4 blade connector. You still need to find and splice into the reverse wire if you are trying to install a more complicated connector. The reverse wire is also needed for a backup camera.
I ended up running a 8 gauge stranded wire from under my hood to the back. I then installed a small power block that I got from Home Depot. From there I ran power to the 4 blade box you see in the picture and also ran power to the hitch connector that I ended up using.
The easiest way to install is to not drill anything and simply run the wires up the inside of the door hinge to the pre-drilled hole covered by the black plastic pop-in cover. I looked for better options and ways I could hide the wires, no easy way to do this even if you drill through the floor pan.
Made installing trailer wiring very easy on my cargo van which had no factory trailer harness. Plugs-into factory light harness. Connect to the existing ground and run a power wire and it's done.
Note: Plan the run for the 4-wire connector and make sure it will reach. I used a factory hole in the left rear door hinge post with a grommet. Just remove the factory 1.25" plastic caplug and carefully push the 4-wire connector through the hole. It is tight, but will fit without re-drilling the hole.
Watching the video of how to install the kit gave me the confidence to buy the kit. I was at a total loss not being able to find the trailer harness in my new van. The video showed that the van does not have any trailer harness and it needed to be installed. I also like that it showed two kits. I needed the kit with added power for sure. We have a camper. Thanks for showing me the way Etrailer.
I put this wiring harness into my 2006 GMC Savana (with extended wheel base). Every component was well made. It was simple to install. (The videos are wonderful.) It has performed flawlessly since then.
The installation videos were worth their weight in gold, and the actual installation was nearly as easy as the professionals made it seem. I installed mine on a 2004 Chevy Express, and every part fit exactly as described except the zip ties. They were to small to be of any use, and when I tied two of them together to make a longer tie, they snapped under the slightest tension. Over all, it wasn’t a serious setback, they are cheep, and I just used some I had in hand. The included wire designed to run to the battery was about 10 feet too short for my project, but I was installing it on a 15 passenger vehicle. Anything shorter, and the kit would have been perfect as is. Again though, the wire was fairly inexpensive, and available at any auto parts store. All said, generally a good kit that worked well for me.

I agree, I wish there were more plug-n-play options with a 7-way. I see that you also ordered the # ETBC7L, how did that install go for you?
