Installation
This custom-fit T-One connector plugs into your vehicle's wiring harness, which is located at the rear, along the driver's-side frame rail. Once you've plugged in the tow harness connector, locate the gray connector between the truck's battery and the fender at the front of your vehicle. Plug in the fuse holder wiring harness. Then attach the ring terminal at the opposite end of the harness to the positive terminal on your truck's battery. Insert the included 10-amp fuse into the in-line fuse holder.
Once installation is complete, the 4-way flat connector will be stowed beneath your vehicle, near the trailer hitch. A mounting bracket (sold separately) is recommended to keep the connector secure.
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.
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.

Quickly and easily install a 4-way trailer connector on your vehicle with this custom wiring harness. T-One connector plugs directly into existing wiring - no cutting, splicing or tapping required. Powered ModuLite reduces strain on wiring system.The product arrived fast as I needed it ASAP. Great fit with easy instructions. I was at the Toyota dealer service department getting other items fixed like the evap system. I asked them to install the part. They said, plug and play with one wire at battery, Yes. So they broke the pigtail clips on my vehicle and pulled out a wire on the connector. Now my left turn fast flashes every time I apply the brake. WTF,,,, So now I have to order the special connectors from connector experts, wait three or four days, then hard wire in the new connectors. My dealer service department broke four things that day by just trying to set computer to clear code. I could go on and on with the other three items but don't want to waste your time. You folks are top notch perfect number one in my book. I have recommended you to several folks and to the Panhandle Trailer Service in Scottsbluff NE. Thanks again.
Installed on a 2000 Tundra. Easy as can be. The truck already had unused factory connectors at the battery, and under the bed at the back on drivers side. Take the protective caps off them, hook these up, and secure the module to the back of the truck body underneath after cleaning it. Connect to battery hot terminal. Secure all using some zip ties (provided). And==> DONE.
Ordered on a Monday night, sitting at my doorstep Friday.
Great products and service, as usual.

Both harnesses are well made and fit correctly. Instructions were clear. Vary satisfactory. Units replaced a older one piece harness the was malfunctioning.
Everything went great. Good instructions, product build was right, wiring harness went on just like the vids.
