    • Compatible with 5-pole, 6-pole and 7-pole adapters (sold separately)

    • Locate connection points in rear cargo area
    • Plug in T-connector
  • Includes a tail light converter to ensure that your vehicle's wiring matches that of your trailer
  • Constructed of 16-gauge bonded wire

    • Tail lights: 4.2 amps per circuit
  • 1-Year limited warranty


Installation

This custom-fit T-One connector plugs into your vehicle's wiring harness, which is located behind the driver's-side and passenger's-side interior trim panels in your rear cargo area. These panels are near the rearmost doors of your van's cargo area.


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, we're going to be taking a look at the T1 vehicle wiring harness with the 4-pole flat trailer connector. This product is going to fit a 1996-1999 Chevrolet Express van and GMC Savannah van. It's going to provide a 4-way flat trailer connector at the back of your vehicle to power your trailer's signal lights. This is compatible with 5-pole, 6-pole, and 7-pole adapters; adapters are sold separately. It's going to come with a dust cap for the 4-way flat connector. That way, you can cover up the connection points when the plug is not being used. The black box right here, this is going to be the included tail light converter.

This is going to ensure that your vehicle's wiring matches that your of your trailer's. The unit's going to connect quickly and easily; you don't have to worry about cutting or splicing any wires. All you have to do is locate the connection points in the rear cargo area. The connector with the yellow wire is going to go towards the driver's side. The connector with the green wire is going to go over to the passenger side of the vehicle.

Locate the connection points and plug in your connectors. These plugs are going to match up perfectly with the ports on the vehicle. Then you can use the included locking tabs to get it fully secured. Once you have that connected, you'll need to mount your converter box. You can do this using one of the included screws or the large zip tie. That way, you can get the box secured and out of the way in a safe location.

Once your install is complete, the 4-way connector is going to be stowed in an out-of-the-way location within your cargo area. Plenty of wiring here; that way, you can extend it out the back of the van and make your connection when you're ready. Then you can wind it back up and stow it away when it's not being used. It does come with detailed installation instructions to walk you through the entire process step-by-step. It is recommended that you use a small amount of dielectric grease on all your electrical connections, like the plugs on the vehicle and the 4-pole connector itself, and that grease is going to help prevent corrosion. If you need some of that, you can find that right here at etrailer.com.

The maximum amperage for the stop and turn lights is 2.1 amps per circuit, and for the tail lights, it's 4.2 amps per circuit. That's going to do it for today's look at the T1 vehicle wiring harness with the 4-pole flat trailer connector.

I looked for a long time trying to find the right wiring harness for my van. This thing was awesome. It took me a total of about 20 minutes to hook it up and secure everything. This is by far the easiest way to hook up a trailer plug. Plus there are no wire splices to get wet.and corrode. The best part is everything I ordered showed up in 2 days.I would definitely order from here again. 98945

Ask the Experts about this Tekonsha Custom Fit Vehicle Wiring
Do you have a question about this Custom Fit Vehicle Wiring?


  • Trailer Wiring Connector for 1999 Chevy Express Van
  • Attempting to wire a 4 pole like the # 18002 into the taillight system of your 1999 Express won't work, as you've found. The 1999 Express uses what is referred to as a separate or a 3 wire taillight system, where the running lights, turn signals and brake lights are carried on 3 different circuits. If your van had a 2 wire system, where the running lights were on one circuit and the turn signals and brake lamps were combined on the same circuit, the 18002 would've worked fine, but since...

  • Installing a Brake Controller on a 1999 GMC Conversion Van
  • There are two possibilities. If your 1999 GMC Conversion Van has a tow package, there will be a port in which to plug in a wiring adapter from the Hopkins Agility Electric Brake Controller, # HM47294, to the port. It is part # HM47795. I have included a link to the installation details below. You would then need to install an Adapter 4 Pole to 7 Pole and 4 Pole, # 37185. But, if the van has a round plug with a cap inside the driver side frame rail instead of a bundle of wires in the jack...

  • Where Does the Trailer Wiring Harness Install on a 1996 GMC Savana Van
  • You are correct. The Tow Ready wiring harness, # 118335, plugs in line with the tail light wiring and you will not have to splice into the wires at all. I have included a link to the installation details for you to view. Models that originally came with a 4-Way from the factory but need a replacement would use a different harness, # 118240. I have included a link to a video that shows how this harness installs.

  • Installing 4-Pole Trailer Connector on 1992 GMC Safari
  • At one time, I believe there was a plug and play-type connector available, but due to the age of the vehicle and low demand, our suppliers no longer have them available. The lighting system of the first generation Safari is pretty simple. You can use our hardwire kit, part # 18252. Use the included circuit tester to find the correct functions behind the vehicle tail lights. Connect the white wire to a good ground, the brown wire to the tail light circuit, the yellow wire to the left...

  • Recommendations for a 7-way on a 2007 GMC Savana Van
  • If your 2007 GMC Savana Van has a 7-way it should be either near the hitch underneath the rear of the vehicle or possibly if you open the rear doors it might be somewhere near the back, inside the vehicle. If your vehicle has the tow package it should have a 7-way. If you do not have the tow package you are going to need first a 4-way and then a 4-way to 7-way adapter. For a 4-way you would want a Tow Ready Custom Fit Vehicle Wiring # 118392. Check out the installation instructions...
