Wiring for trailer lights is simple with this Curt T-Connector Vehicle Wiring Harness. It plugs directly into the factory tail light connectors, giving you a 4-pole flat trailer connector without having to cut or splice a single wire. Everything fits cleanly, and it’s ready to go as soon as you plug it in.
The harness has an integrated converter that makes sure your trailer lights get the correct signals for running, brake, and turn lights. It takes care of the difference between vehicle and trailer wiring systems so your lights stay bright and in sync every time you tow.
Good grounding is key to avoiding dim or flickering lights. This harness connects securely with a clean metal-to-metal ground point, helping current flow properly through both the vehicle and trailer circuits. When everything’s grounded right, your lighting stays strong and consistent on the road.
The 4-flat plug gives you all the basics—running lights, brake lights, and turn signals—in a universal connector that fits most small and mid-size trailers. It’s durable, easy to unplug when not in use, and stays protected with a good connection every time you hook up your trailer.

Hello neighbors, Steven here with etrailer.com. Today we're looking at our Curt T-connector Vehicle Wire Harness with our four pole trailer connector. Now folks, this is a custom fit application. It fits a 01 through 2006 Mitsubishi Montero. Double check that though with our fit guide here at etrailer.com. Top center of our homepage, enter your year, make and model and any kind of other information it asks you to ensure you're getting the correct parts the first time.
Now folks, this will provide you with a nice four pole flat connector or a four-way, some people call it, at the back of your vehicle. And that'll let you plug in your trailer and then in turn, power up your trailer's turn signals and lights. It is technically compatible with a five, six, or seven pull adapter. You can get those separately here at etrailer.com. And it's a quick, no splice, no drill connection.
So at the back of your vehicle in the cargo area, you're gonna pull off a couple panels per the instructions. Follow those and you'll unplug the taillight connector. You'll plug one of these guys back into the taillight and you'll plug the taillight connector in the other one. So that's why they call it a T-connector. It's making the letter T, very simple plug and play connection.
Super simple. Now you've got this black box here and a double sided adhesive that would go on here and get pressed into the vehicle behind one of those panels, again per the instructions. And this guy is what they call your brain of the the whole kit or the surface mount technology. It's gonna give you consistent, reliable output of voltage and amperage. And it's also gonna con protect the vehicle against back feed.
The max amperage on your stop turn lights is three amps per circuit, while five amps per circuit's gonna be on your taillights. You do also get a ground wire here to ground it to the metal frame of the vehicle. You got a nice self tapper here to do that. You also get a dust cap to go over the four pole connection whenever it's installed and all the zip ties to install it. Now once this is installed in your cargo area, it does actually come out and go underneath the vehicle. So I recommend getting an electrical mounting bracket that's sold separately here at etrailer. The first one I recommend is what they call a short bracket. It's 18140 and it has a hose clamp included that's gonna get you around the hitch and it's going to mount up to and mate with a C42CR connector. And those two mounting brackets together will let you mount this up out of the way, nice and tight and clean next to the hitch tube on the hitch itself. That way you never have to look for it whenever you're hooking up your trailer. Folks, that's gonna wrap it up. You got a nice one year limited warranty with this connector today. And I am Steven, thank you so much again for your time. Stay safe out there, as always while you're towing.
