Installation
This custom-fit T-One connector plugs into your GMC Sonoma's wiring harness, which is located at the rear, along the inside of the driver's side frame rail.
Once installation is complete, the 4-way flat connector will be stowed beneath your GMC Sonoma, 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.

Today on this 2001 GMC Sonoma we are going to install part number 118359 from Tow Ready. This is their T-one wiring harness. The first thing we need to do is separate the factory connectors which are on the driver side frame rail. We pull back on this latch right here and pull it apart. OK, take the T-harness and let us plug them back together. Now we will take our ground screw and run it right directly to the frame. We will just take our wire harness now and we are just going to route it over to the center of the hitch. Within a matter of minutes we are finished with our install. And there you have it for part number 118359.

This wiring connection couldn't be easier to use. Instead of tapping into each of the wires under the vehicle, this just plugs in-line near the rear turn signal. It takes less than 2 minutes to install, and with the factory connections, keeps the wiring from corroding due to water. This product is a great value, and a must for do-it-yourself vehicle wiring.59812
