Quickly and easily install a 4-way trailer connector on your Chevrolet Colorado with this custom wiring harness. T-One connector plugs directly into existing wiring - no cutting, splicing or tapping required. Circuit-protected converter guards against shorts.

Installation
This custom-fit T-One connector plugs into your Chevrolet Colorado's wiring harness, which is located beneath the truck bed, near the driver's-side frame rail.
Once installation is complete, the 4-way flat connector will be stowed beneath your Chevrolet Colorado, 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.
Circuit-Protected Tail Light Converter
A tail light converter 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 Chevrolet Colorado's three-wire system need to be combined so they are compatible with the wiring system of your trailer. The tail light converter combines 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 Chevrolet Colorado operate.
This converter safeguards itself and your vehicle against possible electrical shorts and overloads with integrated short circuit protection. Just install the connector as indicated and rest assured that the wiring system of your vehicle will remain feedback-free.

Today we are working on a 2009 Chevrolet Colorado. We will be installing Tow Ready T-One connector part number 118301. Our first step is going to be locating the vehicles rear tail light wiring harness here, up above the spare tire. Then separating the manufacturers connections. Press on the locking tab and separate the two connection points. Now we can take our new Tow Ready connector, which has identical connection points and connect in line with the manufacturers harness. Press them together firmly, so they securely lock in place. Repeat this step on both sides. 0:38
With our connections made, we need to locate a suitable grounding point for our white ground wire. Right here on the bottom side of the cross member is a perfect location to mount our ground wire. I will go ahead and use the self tapping bit from our installation kit to install it now. With our ground wire attached we can go ahead and mount our converter box. Here on the back side of the hitch is a perfect location to do so. It is a clean and flat area. We will remove the double sided tape and firmly press it against the back side of the hitch to get a good cohesive connection. 1:18
With our converter box mounted, we can route our new 4-pole connection over to the center of the hitch. With my 4-pole connection routed, I have some extra wire. What I am going to do is take the zip tie that is provided in the installation kit and wrap it around my extra wire and converter box to tidy up our wires just a bit here. I am going to take one more black zip tie, and tidy up the loom between the converter box and the connection points. Clip off the extra length from the zip ties. This completes the installation of Tow Ready T-One connector part number 118301.

The installation was really simple; I was literally able to test it in two minutes! Dressing the leads and tie-wrapping everything took an additional 4 to 5 minutes, but that was all. The overall quality of the device is first class. I was impressed with the service and follow-up contact from beginning to end. These folks are doing their best to be a top-notch company; they will do well. RB77309

The wiring harness that I ordered from E Trailer came faster then I expected! The only thing faster was installing it!! The video I watched on the E Trailer web site showed me exactly how it needed to be installed. Again it was on the money. Using my new motorcycle trailer is now an easy plug and haul away. Couldn't be easier! Thanks E Trailer.71973

The product was exactly as pictured. It installed very easily in approximately five minutes. More time passed waiting for my cordless drill to charge than the actual installation. The self tapping screw for the ground wire was great. The installation literally was unhooking the existing wire connectors, putting the T connector between them, and then running the wire towards the ball hitch. I have yet to hook anything to the connector at this time to enure all is functioning correctly though will tow a trailer in another week to test it. 52625

I am quite pleased with my recent purchase. The hitch fits perfectly and the T one electrical hook up was sooo easy that I let my 3 year old great nephew make the connection. He's not afraid to try new things just like his Aunt. :) To install the hitch I made a crude ramp (inclined plane) from 2x4's and bricks. Kind of like when the Egyptians built the Pyramids. I highly recommend etrailer to anyone looking for anything from your company. The prices were the lowest of all the sites I checked. Delivery was free and your company arranged for a delivery a full two days earlier than originally quoted. 32143
