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.

Video Transcript for Trailer Wiring Harness Installation - 1997 GMC Savana

Alright. Today on this 1997 GMC Savana, were gonna install part number 18335 from Tow Ready.Now the foreign harness connects inside the van so we have to open up the doors and get to the wire harness on the inside. Now this is a cargo van so getting to the wire harness is really easy. Its all exposed. Ok, if this is a conversion van, we have to remove the interior panels to get access to this wire harness here as well on the other side. This is a wire harness right here.

Were gonna go ahead and disconnect. Just push in on this tab right here and you can pull it apart. This could be particularly stiff thats why I use a screw driver. Then well install the T-One harness in between, run the wires down then shoot it out here and out the lower hole. Well just leave that alone for now.

Now well take our other half of the T-connector, with the green wire, were gonna run it up and over to the other side to the same connection on the passenger side. Now, all we gotta do is take our extra green wire and zip tie it to the factory wire harness to take up the slack.Ok, at this point, you have an option with the wire harness with the 4-Pole. Now, you can leave it to the side and tuck it in the corner and when you need to use it, you just pull it out and shut the door on it. The door seal is soft enough so you wont smash the wires. Just make sure you stay away from the latch.

Or, also, we can run this out towards the bottom and out towards the outside. Okay, well take the wire harness and drop it down towards the bottom. To run it outside, were gonna go ahead and remove this panel, pull our wire out and put the panel back in place. Theres the wire harness. Well fold it over to the side just like this then put the cap back into place.

Now were gonna take our wire harness and run it over to the hitch. And from here, you can mount it anyway you want zip tie it to the hitch or use a specialty bracket.Alright, to mount our 4-Pole in this application, were gonna use part number 118149 from Tow Ready. So whats gonna happen is our wire is gonna fit between the prongs right here. And with the Tow Ready wire harness theres also a cutout for the cap as well. Lets take the two halves and, well snap them together and theres a couple of small screws to the holes to tighten it in place. And then if your 4-Pole is still loose inside, theres a set screw right here that you can tighten down, enough to make contact so it doesnt move. You dont have to crush it. Our mount uses zip ties to stay in place. Now you can mount this bracket anyway you like on the cross tube of your hitch. In this case, were gonna mount it like this. Well run our zip tie through and around the other side. Once youre satisfied with the placement of your bracket, go ahead and tighten down the zip ties.Alright, with that, that will finish for our install of part number 118335 and part number 118149 both from Tow Ready for 1997 GMC Savana van.

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

Fantastic products, service and delivery time! I just re-wired my trailer, and 1999 Chevy Express Van with products and support from eTrailer.com. A video showing me the exact products I needed, as well as how to do it, made the job a simple one! Products arrived quicker than if I'd ordered them from a local trailer shop. Thanks. 84361

  • 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...
