T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector

by: GromBeardo10/22/2023

Used this on my AWD Express Moto Van. Straight forward easy hookup to the factory harness. Plenty of length on the trailer side wiring to run it out the back and connect to the trailer. Definitely worth the money to save the hassle of tapping into the factory harness.1685059

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.652054

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.739394

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.252405

It didn’t last a 6 weeks

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.698752

Works great, only wish there were more zip ties with the kit1584273

This wiring harness was top notch! plugged up easily and quickly and did exzctly what it was intended for1533624

Great website, easy order, experts helping in the phone, awesome fast shipping. Great company.1669021

I can't even write a review because the item was stolen due to poor packaging. The item was sent with the shipping label slapped on instead of putting it in a separate box. Disappointed.1285244

Piece of cake! Works as advertaised. 1651733

Super easy to hook up, used on a 2012 chevy express extended passenger van with the smaller engine. Hook up is in the power connectors behind the brake light on both sides, main power on drivers side, accessed behind the interior trim. Plug in main connector, loop passenger side connector over/around obstructions and plug in.

Directions are spot on. 1675468

Perfect fit, so easy to install 1668152

This harness fits right in the original wiring of the van. It was quick and simple to install.1497182

Great wiring harness and fairly simple to hook up. My van had its issues to get it to the proper places then it's just plug it in. No splicing required.1397277

by: Eric05/20/2020

This wiring product worked perfectly plug and play. Hardest part was running wires from inside van to the outside. There is a removable cap at bottom of body pillar under brake lights. Easiest to remove cap and run single wire up and tape harness and pull back out.
Only problem I noticed is my van was prewired so I bought wrong kit but this kit worked perfectly so I just stayed with it.
Works even better attached to the heavy duty hitch that I got from etrailer too.
You shouldn't be disappointed with this easy to install product!800893

Its been a year and still working without any issues.

The wiring harness worked out very well. I ran it in flexibale plastic conduit to protect the wires. Wire tied and electrical taped it to existing wiring harness...1324660

by: Alan02/02/2018

etrailer did a great job as usual but the vehicle this part is designed to fit does not have any existing openings to pass the connectors through so the wires all had to be cut and spliced back. I might as well bought an inexpensive vehicle side pigtail and spliced unto the wiring harness. It would have gone faster. 472474

This particular wiring harness is meant to remain in the cargo area of the van until its needed. When you need to use it, just run it out the back doors and shut the doors. The weatherstripping around the doors is thick enough that the wires will not get pinched or damaged, as long as you avoid the door latches. Installing the harness in this manner protects the connector from damage and from moisture.

Easy install. This wiring harness worked well for about 6 months. Now when I hit the brakes the trailer lights do not work properly.

Mark, thank you so much for your order and your feedback. The number one cause of faulty wiring harnesses is a loss of ground. To troubleshoot your wiring harness, I recommend checking out our wiring FAQ, which can be found at the following link:
