Easily add a 4-way trailer connector with this custom-fit harness. The T-connector plugs into existing wiring - no cutting needed. Powered converter protects vehicle circuits and ensures consistent trailer lighting for safe towing in any conditions.
The vehicle's 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.
Plugging in a trailer shouldn't mean tearing into your vehicle's wiring. This custom-fit T-connector snaps directly into your factory wiring harness, so you can get your trailer lights up and running without any cutting or splicing. Just plug it in, and you're ready to tow.
A well-lit trailer is a safe trailer. This 4-way wiring harness keeps your trailer's brake lights, turn signals, and running lights powered and in sync with your vehicle. Whether you're hauling a boat to the lake or a camper to the mountains, your lights stay bright and visible.
Some vehicles can't handle the extra electrical load of trailer lights. The built-in powered converter draws power directly from your battery, ensuring a steady, protected current to your trailer while keeping your vehicle's circuits from overloading.
Towing means exposing your wiring to dirt, rain, and road grime. This harness features fully insulated wires and a sealed converter, helping to prevent shorts and corrosion. It's built to withstand the elements so you can tow with confidence in any weather.
No extra trips to the hardware store - this kit comes with everything you need. With fuses, zip ties, and connectors included, you can complete the installation without hunting down extra parts.

Hi, everyone. Steve here with etrailer. Today we're taking a look at the Curt Custom T-Connector Wiring Harness with four-pole flat trailer connector. Now folks, this is a custom fit application as I mentioned. Make sure you have a 2010 through '22 Lexus RX 350 or RX 450H with the factory tow package. And you can verify that information.
I recommend you verify that information either with your local dealership or on our vehicle fit guide here at etrailer.com as far as entering your year, make and model. Make sure you have those kinda things already in place. Now, as I mentioned, this is gonna plug directly into your existing vehicle wiring connectors that should already be on that vehicle. So, should just be a simple plug and play. Then, you have a ground wire here.
You got the main brain of the operations. This is a power converter. It's gonna use direct battery connections to avoid overloading circuits. And it does all that through the connectors. And then, of course you have a dust cover here.
This will go on this whenever you're installing it to keep dust and debris out. And then you have some foam backer double-sided adhesive that's for sticking this in place. And you have a spot for a screw that's included as well. And you have a lot of different little mini fuses. So, make sure you're reading instructions.
You're gonna be putting them in place in your fuse box, most likely. This is weather-resistant. It's got a protective sleeve on it as you can see. And everything here has been sealed. The connectors and everything will give you a nice solid connection. And again, you're gonna get everything here needed for the connection. And again, this will support brake light, turn light, and rear lights as well. As always, reach out to us here at trailer if you have any further questions about this or any other products. And have a great day.
This product was difficult to find, local Curt dealers said they couldn't get it. Found it on eTrailer and they shipped it out right away. The part number is different than on the package, but it's exactly what I needed.
So far, always the right stuff!! It’s not right the first time, I pay closer attention the second time. Thanks!
