Installation
This custom-fit T-One connector plugs into your vehicle's wiring harness, which is located behind the driver's-side interior trim panel in your rear cargo area. You will need to remove the storage compartment door or trim panel to access the harness.
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.
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 vehicle'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 vehicle operate.

Today on this 2004 Chevrolet Venture we are going to be installing Tow Ready T-One connector, part number 118355. First we are going to access the rear cargo area. Then we are going to remove the side panel access door. Take it off and set it out of the way. You will see there are two fasteners here holding the black cover on, we are going to remove them now. We will set that out of the way. :23
After you remove the black cover panel you will see the white plug. This will be our new connection point for our Tow Ready connector. Now that we have located our connection point, we will take our Tow Ready connector and plug it in. Next we are going to locate our wire. As you can see it already has a ring terminal on it. We will take the supplied self tapping screw and run it into the sheet metal here behind the trim panel. :45
With our ground wire attached we can go ahead and peel back the double sided adhesive here. What we are looking for is a flat, clean surface to mount our converter box to. We will run our 4-pole connector into the cargo area and reinstall our black cover and the interior trim door. With all of the connections made that completes the install of our new 4-pole connector. To use it, we will route it here, to the outside of the vehicle. The weather seal is thick enough that it will not be harmed when closing the back hatch on it. This completes the install of our Tow Ready T-One connector, part number 118355.

Most of my remarks are on the Hidden Hitch review. This connector was another quality product. The on-site video showed me EXACTLY what I would find and where. It was a simple "plug-and-play". Lights work perfect, was enough cable, all the parts were there. Simple. You guys at "etrailer" must actually install these products because everything was right. I can't say enough about how helpful the installation video was!!!!!!!!!!!! (2004 Chevy Venture)55694

The wiring harness I purchased was extremely easy to install and works great. The hardest part was getting the ground screw in because I did not have the right tools for my drill gun. Went across the street to hardware store and bought it. It probably took me 15 minutes to get the whole project done and lights tested. I would recommend this product to anybody who needs to wire there vehicle. On a side note I did buy dielectric grease just to make sure I got good electrical connection49409

Overall, very happy with this product. The screw tab on the black box could stick out further from the body of the box, but I was able to make it work. Everything else worked as the instructions said, and the tail-lights and turn signals on the trailer lit up.44745

Very easy. Did plug and ground through the 12 volt accessory plug door. Pry out the black plastic panel that the 12 volt female plug is on and then unplug its wiring. Adhere to the directions, being careful where you drill the 3/32 hole for the ground wire. I did the ground wire first. I drilled the hole for the grounding screw with a Dremel like tool. It was then a snap to plug in the white plug and stick the black box to a flat spot to the right of the white plug. I then let the trailer plug slide down in back of the plastic side wall and fished it out with my fingers when it reached the floor of the back deck. The air conditioning fan housing looked like it would be annoying, but I found that it was not a problem in doing the work. I did everything through the 12 volts plug opening. There is no need to pry open any other panels. I am very happy with the product and etrailer.com.40165

The trailer wiring harness installed as the instructions said. Took me a little longer to install than estimated since I have the rear A/C and had not installed one on this make of vehicle before. If I put another one on, it would go very quickly. Works great. Very pleased. Shipping was very fast. Ordered on Thursday, received on Saturday. Completed the instillation that afternoon. Thanks for your products and services. Will buy from again. The video for the instillation was great. Thanks for having that on your web site.31538

The product, instructions and your service were all GREAT! Installing the wiring was a piece of cake, and only took about fifteen minutes, with most of that time used to undo a poor wiring job a previous owner of my van had done. The wiring works great, so now I can hook up my boat trailer, and go do some fishing. The next time I need anything auto related. I'll contact etrailer. Thanks again, Dave 28208

Good product, One note on a 2000 olds silhouette with the air compressor you have to cut the plugs off and attach it to the factory harness you should have with your van, at least according to the olds dealer. 18057

Easier than Advertised I was expecting a challenge after researching the installation procedure for this wiring harness for my Montana EXT AWD. Was pleasantly surprised that the factory connector was accessible through the panel by simply removing the air compressor panel. Needed a washer for the ground screw as it would not snug up tight enough to hold the terminal. Just make sure the terminal cannot be turned by hand before replacing the rear interior panel. 3342
