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.

Hi everybody. Andy here with etrailer. Let's take a quick look at this CURT T-connector vehicle wiring harness with four pole flat trailer connector. Now this harness has been designed to fit your 2025 to current Volkswagen ID-Buzz and on custom fit parts such as this harness, I do recommend taking advantage of our vehicle fit guide here at etrailer. Just pop in the year, make, and model of your vehicle and our fit guide will confirm if this harness will work for you or if we have something comparable that will work for you. But this harness is designed to make adding trailer lights to your vehicle really straightforward.
Even if you're not super experienced with wiring, the biggest advantage is that this is a custom fit for your ID-Buzz. So this is going to plug right into your existing wiring. And what's nice about that is no cutting or complicated splicing is gonna be needed with this harness. Once it's connected, it's going to power all of the basic trailer lights like your brake lights, turn signals, and running lights. So everything's gonna stay safe and legal when you're towing.
And as you can see here, our four-way flat does have this tethered cap here included. So you can just put that cap over the four-way plug when it's not in use to keep that nice and clean. Now this uses what is typically called a powered converter. This is going to connect directly to your vehicle's battery. And this is important 'cause this is going to protect your vehicle's electrical system from being overloaded, especially with newer vehicles that have more sensitive electronics.
The wiring itself is insulated to help prevent shorts or interference, and it's built to handle the elements with weather resistant materials and sealed connections. So you're not gonna have to worry about corrosion over time. As for installation, this kit is going to come with everything that you need to get this installed. You're going to get a fuse, connectors, cable ties, the wiring here, everything that you're gonna need along with instructions. So you're not gonna have to run, make extra trips to the hardware store to get bits and pieces of other bits of hardware wiring that you think you're gonna need.
This is going to include everything that you're going to need. Now, typically you're just going to need to access your vehicle's wiring harness to plug this in. That usually can be found behind trim panels, under the cargo floor. You might have to lift some carpet or remove a panel, but once you get to it, the actual install is gonna be relatively straightforward. Again, the instructions will guide you through where you can find that wiring harness on your Volkswagen. It is also recommended that you use a small amount of dielectric grease on all of your electrical connections, like the plugs on your vehicle and the four pole flat connector itself. That grease is designed to help prevent electrical failures caused by corrosion and moisture. So on your screen, I do have our part number for that grease. You can take that number again, pop it in the search field of our website. That will take you to that grease and you can add that to your order. One final thing I wanted to mention, this is designed for do it yourself install installation, but if you feel better with having someone else do the install for you on this product page. Typically, underneath the photo section, you will find a link that will take you to our installer locator. Click that link, answer the questions that it has for you, and that locator will find an installer in your area that etrailer has partnered with to do the installation for you. Well again, my name is Andy. Thank you for joining me.
