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. Circuit-protected converter guards against shorts.

  • Provides a 4-way flat trailer connector at the back of your vehicle to power your trailer's signal lights
    • Compatible with 5-pole, 6-pole and 7-pole adapters (sold separately)
  • Connects quickly and easily - no cutting or splicing of wires

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.


Once installation is complete, the 4-way flat connector will be stowed in the jack storage compartment of your rear cargo area.


It is recommended that you use a small amount of grease on all electrical connections - the plug 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 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.


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.

Also the best price anywhere.

Easy plug in design. Tougher location on my Equinox to install than I thought. I had a tough time getting the wires loose in the vehicle to plug this unit into. Once I had it all hooked up, it powered my trailer lights well.

  • Can A 2006 Pontiac Torrent Tow A 2400 Pound R-Pod?
    Hi Adele! Your 2006 Pontiac Torrent, which is a name I haven't heard in quite some time, is indeed rated to tow up to 3,500 pounds. With that said, it is getting a little up there in miles and age, so I would have a trust worthy mechanic (absolutely NOT a dealership) go over it to make sure everything is still in good order. If they give you the all clear, there is no reason your couldn't tow a 2,400 pound R-Pod 18 wherever you want! Do you have all the parts needed for towing? If not,...

  • Can Surge Brakes be Installed on a Coleman Taos Pop Up Camper
    Yes, you can install surge brakes on a trailer. We have an FAQ that details everything needed to add hydraulic surge brakes on a trailer like your Coleman Taos. Typically on pop-up campers you see electric brake setups, but there's no reason you couldn't add surge brakes to the trailer.

  • Parts Needed to Install a Brake Controller on a 2006 Chevrolet Equinox
    The first thing you will need to install a brake controller in your 2006 Chevy Equinox will be to install a 4-way trailer connector. This will carry the tail light circuits of your trailer. For this you would want a Tow Ready Custom Fit Vehicle Wiring # 118391. I attached installation instructions and an install video that shows how this installs, its a pretty simple install process. Next you will need to convert this 4-way to a 7-way so that you can install and operate a brake controller....

  • Trailer Wiring Harness Recommendation for a 2005 Chevy Equinox
    There are a couple of options for trailer wiring harnesses that fit your 2005 Chevy Equinox. I have included a link to the right to them for you. The prices are also listed. Out of the options I recommend # 118391. It is the more popular option, cost less, and works well. I have linked a video showing how it installs on a 2005 Equinox for you.

  • 6-Way Round to 4-Way Flat Adapter Recommendation for a Camper
    If you are looking for a way to convert the round 6-way on your camper to a 4-way you would need a product like the Adapter 6-Pole Round to 4-Flat # 47305B. The 6-way male end of this adapter will plug into the 6-way on your camper and will provide a 4-way connection on the opposite side of the connector. The Wiring Harness part # 118391 that you referenced would not work for you as it is a wiring harness designed for Chevy Equinoxes.

  • 4-Way and 5-Way Adapter Recommendation for a 2005 Chevy Equinox
    It sounds like you have a trailer that has a 5-way trailer connector on it with surge brakes and you are looking for a way to wire up your 2005 Chevy Equinox so that it will have a trailer wiring connector compatible with your trailer. What you are going to need to do first is install the T-One Vehicle Wiring Harness # 118391 in your vehicle. Next you will need to use an Adapter 4-way to 5-way part # 20036. This will plug into the 4-way of your vehicle and then the blue wire will tap into...

  • Brake Controller Recommendation and Install for a 2008 Chevy Equinox
    If you are mechanically inclined at all and would rather save yourself some money you could easily install a brake controller in your 2008 Chevy Equinox. You will need to start with a 4-way (if you do not have one). For that you would want the # C56012. I attached an install video for this harness for you to check out that will walk you through the process. From there you would need to convert the 4-way to a 7-way so that you can install the brake controller. For that you will want the...

  • Parts Needed to Install a 7-way on a 2008 Chevy Equinox with 4-Way
    What you will want to install on your 2008 Chevy Equinox is the part # ETBC7. This comes with everything needed to install a fully functional 7-way on your vehicle. Since your trailer has an inverter you will at least need a 12 volt accessory circuit on the 7-way. Most likely your trailer has brakes and you will need a brake controller. For a brake controller I would recommend the Prodigy P2 Brake Controller part # 90885. This is our best selling brake controller because of how well it...

  • Adapting Existing 4-Pole on 2005 Chevy Equinox to 7-Way Plug on 2003 Coleman Taos Camper
    You would need an adapter like part # 37185 to convert the existing 4-pole connector to a 7-way. The adapter has a 4-pole connector on it that would plug into the existing 4 pole on your vehicle, with 4 additional wires that would need to be connected (see provided photo). If your camper is equipped with electric brakes, you will need a brake controller like the Tekonsha Prodigy P2, part # 90085 to actuate them. Using our Brake Controller Install Kit, # ETBC7 would be your best bet in...

  • Bike Rack Recommendations for a 2005 Chevrolet Equinox with a Rear Spoiler
    I do not recommend using a trunk mounted bike rack on your 2005 Chevrolet Equinox if it has a rear spoiler. The upper straps of the bike rack must attach to the top edge of your rear hatch and the only way to do that is to go over your spoiler. Spoilers are not designed to support the weight of a bike rack or bikes and it is likely that the spoiler will bend and break. Instead, I recommend using a hitch mounted bike rack like the Thule Doubletrack Pro XT Bike Rack, # TH92BJ. This bike...

  • Is The Draw-Tite # 36408 On A 2006 Chevy Equinox Hidden Or Fully Exposed
    The Draw-Tite Class II 1-1/4 Inch Hitch # 36408 that fits the 2006 Chevy Equinox will be mostly hidden underneath your bumper and rear fascia. The only part of the hitch that you can see on the rear is the receiver tube that is sticking out from under the rear fascia. I am sending a link to the installation instructions on the Draw-Tite and I have a video link that shows a hitch being installed on a 2009 Chevy Equinox. The hitch being installed is a different part number, but the position...
