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 tail lights. You will have to remove the rear threshold plate, privacy screen, storage covers, floor covering, and some interior paneling to access this harness.
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 your rear 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 your vehicle runs on a multiplex wiring system, the wiring needs to be converted to be 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.

Installation went very well thanks to your good video. All the components looked to be high quality and they arrived well packaged and on time.

This worked great, it was "plug and play".
No cutting or splicing, just connect fittings.

This is needed so the receiver can protrude, but the portion you have to trim is underneath the Trailblazer so it won't be noticeable. I've added a cut out from the instructions which show the 4" x 3-5/8" section that requires trimming. Also, I just wanted to add that if you plan on towing with your...
