Installation

This custom-fit T-One connector plugs into your vehicle's wiring harness, which is located in your rear cargo area, behind the driver's-side and passenger's-side interior trim panels. Once you've plugged in the T-connector, run the hot lead up to your car battery. Connect the lead to the included fuse holder, and then connect the fuse holder to the positive terminal on your battery and insert the provided fuse.


Once installation is complete, the 4-way flat connector will be stowed in an out-of-the-way location within your cargo area. It is recommended that you use a small amount of grease on all electrical connections - the plugs on your automobile and the 4-pole connector itself - to help prevent corrosion.


ModuLite Powered Tail Light Converter

A ModuLite power module is built into this T-One connector. Because most trailers run on a two-wire system - wherein the brake and turn signals are carried on one wire - the separate brake and turn signals from your vehicle's three-wire system need to be combined so they are compatible with the wiring system of your trailer. This power module functions as a tail light converter to combine the brake and turn signal functions of your automobile so that they run on one wire to properly activate your trailer's tail lights. Note: This will not affect how the tail lights on your vehicle operate.


With a ModuLite, your trailer's lights will be powered without overloading your vehicle's electrical system. Because the module draws power directly from your car's battery and bypasses the electrical routes that are used by a basic wiring harness, there is virtually no draw on your tail light circuits.

See what our Experts say about this Tekonsha Custom Fit Vehicle Wiring

  • Does Trailer Wiring Harness 118565 for a 2012 Chevy Orlando have a 12 Volt Power Outlet
    On trailer wiring harness # 118565 it has a 4-Way trailer connector for ground, running lights, left turn/brake lights, and right turn/brake lights. The harness does require a direct connection to the vehicle battery to provide power to the trailer lights. But the output side does not have a 12 volt pin. To add a 12 volt power pin you would need to also install # ETBC7. I have included some links that explain the installation of the ETBC7 for you.
