Wiring a trailer can be intimidating, but this Curt T-Connector takes all the guesswork out. It plugs directly into the existing vehicle wiring to create a 4-pole flat trailer connector. There’s no need to cut or splice wires, and everything connects cleanly behind the trim for a tidy setup.
The built-in powered converter keeps the vehicle’s sensitive wiring safe by drawing power directly from the battery instead of the lighting circuits. It helps reduce strain on your system so trailer lights work reliably and evenly. The converter is made using surface-mount technology (SMT), which improves durability and performance while keeping everything compact.
Running the power wire can sometimes be tricky, but this harness gives you flexibility. The 12-volt lead can be routed through an existing grommet in the firewall or underneath the vehicle for a straightforward connection to the battery. That means fewer modifications and a cleaner install overall.
Once installed, the harness provides a standard 4-flat output for running lights, turn signals, and brake lights. It’s the connection most small and mid-size trailers use, so you’re ready to tow safely with fully functioning lights as soon as it’s plugged in.

We do have a good FAQ that assists in helping run the power wire to the battery. Please see the link below. If the adhesive tape does not hold you can use double sided tape with the module to hold it in place.

I have linked the online installation instruction to this comment for you. In these instructions, it does walk through the steps needed for the drivers side installation, including connecting the yellow end of the harness. Then through installing the passenger side with the green-side connectors. I hope this helps clear up any confusion.
