Easily add a 4-way trailer connector to your vehicle with this custom wiring harness. The T-One connector plugs into existing wiring for a simple setup. The ModuLite ensures reliable operation while protecting your vehicles electrical system.
The vehicles wiring harness is often behind a trim panel or under the cargo floor. Some vehicles may require removing interior panels or lifting carpeted sections to reach it, but once accessed, the harness installs easily with quick-splice connectors.
The ModuLite isolates your cars electrical system from the trailer, preventing overloads and ensuring smooth, reliable operation.
The 4-way connector is designed to be mounted near the hitch using a bracket (sold separately) for easy access when towing.
A built-in dust cap keeps dirt and moisture out of the connector, ensuring a clean, solid connection every time you attach to your trailers wiring.
Includes 16-gauge power wire, fuse, quick-splice connectors, and all necessary hardware for installation.

Hi, everyone. Steve here with etrailer.com. Today we're looking at our T-One vehicle wiring harness with a four-pole flat trailer connector. Now folks, this is a custom-fit application, so make sure you're checking our fit guide here at etrailer.com. And sometimes these videos can become outdated, and it could potentially fit newer year makes and models as well. Now, these are going to prevent trailer shorts from causing damage to your vehicle.
You have the built-in ModuLite here, as they call it, from the factory, and then you have your T harness. That's where we get the T from. It makes a letter T. What you're gonna be doing is you're gonna unplug the wiring at the back of your tail lights and then whichever one of these that that one you pulled out plugs into would match up, and then the other one would go back into your tail light, creating that no-splicing connection. And then of course, you're left in the end with a four-pole connection with a nice, handy dust cover cap to go over it when not in use to keep it protected and everything.
You're gonna get a nice length of wire that's gonna go all the way up to the battery, to the power. And then of course, you have an inline fuse, some cable ties, and all your electrical connectors you need to do that. It should be a pretty simple, straightforward installation with the included instructions, and we might possibly have a video of this installed on your vehicle as well. Now, this will work with all trailer lights, it's compatible with LED and incandescent bulbs. And again, that four-way is going to mount near the hitch that you would probably most likely want to purchase separately a bracket to mount that next to the hitch.
Some people cable tie 'em on their hitch, but you can get a bracket sold separately and give it a nice, clean look next to the hitch. Well folks, I think that's gonna wrap it up for our quick look together at this T-One vehicle wiring harness. I'm Steven. Thanks for watching.
