Installation

This custom-fit T-One connector plugs into your vehicle's wiring harness, which is located inside your rear cargo area, behind the tail lights on both the driver's side and passenger's side. You will need to remove the interior trim panels to access this 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.

Easy installation. The entire installation process took less than 15 minutes. The hardest part was removing the vehicle's interior trim panels. Wire harness quality was excellent and the connectors fit perfectly. Overall, I am.very pleased with etrailer products and their customer service team. I look forward to doing more business with etrailer in the future. 79599

This was easy even a mere woman was able to install. LOL! I popped off the panels, unhooked the van's light wiring, matched the wires from the connector to lights wiring, hooked them all together (no splicing yeah), replaced the panels, anchored wiring under the edge of the carpet and under the center part of the van door. Snapped onto the wire harness..... I now have trailer lights. Great product! Shipping feasible, and arrived promptly. 131365

Do you have a question about this Custom Fit Vehicle Wiring?


  • 2-Inch Hitch for 1990 GMC Full Size Van Without Step Bumper
  • We do have custom-fit hitches for the 1990 GMC full-size van without step bumper but these are all Class III types and they are shown on the linked page. No class IV hitches are offered. Two of the hitches, the USA-made Curt # C13016 and the Draw-Tite # 41121, are no-drill installations. I recommend the Curt # C13016 because of its higher 6K towing capacity and its concealed cross tube which gives it a cleaner installed appearance. The written instructions are linked. If you also...

  • Trailer Hitch and Wiring Recommendations for a 1995 Chevy Full-Size Cargo Van
  • Draw-Tite trailer hitch # 41121 fits the full size 1995 Chevy vans like yours and does not require drilling or trimming for installation. It does not fit models with a step bumper and based on your picture you do not have a step bumper so that is not a problem either. I have included a link to the instructions for you. If you plan on doing some towing I recommend etrailer ball mount kit # 989900. It comes with 2 ball mounts; one with a 3/4 inch rise or 2 inch drop and one with a 2-3/4...

  • Installing a Tekonsha Prodigy P3 Brake Controller on 1988 Chevy G20
  • Before you can install the Tekonsha Prodigy P3, # 90195, you will need to make sure that you have a trailer connection installed on your 1988 Chevrolet G20 van. You will need a trailer 4-way flat connection installed on your van. If you do not have a 4-way installed, then you will need the Tekonsha T-One Wiring Harness, # 118338. The wiring harness will connect to your vehicle's wiring by plugging into existing plug in the harness. No cutting or splicing of the your vans factory wiring. Next,...

  • Will Tow Ready Trailer Wiring Harness # 118338 Fit a 1995 Chevy G Series Van with Step Bumper
  • According to Tow Ready, the manufacturer, the Tow Ready Wiring Harness, # 118338, will fit your 1995 Chevy Van, even if it has a step bumper. I have included a link to the installation details for you to view.

  • Differences Between Draw-Tite Hitches # 41121 and # 75121 on a 1994 GMC Van
  • The main difference between the Draw-Tite Hitch # 75121 and the Draw-Tite Hitch # 41121 is the towing capacities of each hitch when a weight distribution system is being used. The # 75121 has capacities of 7,500 lbs GTW and 750 lbs TW when used with weight distribution, whereas the # 41121 can handle 10,000 lbs GTW and 1,000 TW when used with a weight distribution system. I attached installation instructions that apply for both hitches for you to check out. To complete your towing...

  • Recommended Trailer Hitch for a 1993 Chevrolet Van
  • I have a trailer hitch that is a confirmed fit for your 1993 Chevrolet G20 Van, but the Curt # 13028 will not fit on your Van. Draw-Tite has a 2 inch Trailer Hitch, part # 41121, that is a confirmed fit for your Chevy Van as long as it doesn't have a step bumper. This hitch has a Gross Trailer Weight of 5,000 lbs and a Max Tongue Weight of 500 lbs. If your Van does not have a wiring harness already installed you can use the Tekonsha T-One Wiring Harness, part # 118338. If you are...

  • Hitch Recommendation for a 1991 Chevy G30 Full Size Van
  • According to the research I did a G30 Chevy van is basically just a full sized van, so for your 1991 Chevy G30 van you would want the Draw Tite Hitch part # 41121 that you referenced as it has been confirmed to fit. If you plan on doing some towing you might be interested in etrailer ball mount kit # 989900. It comes with 2 ball mounts; one with a 3/4 inch rise or 2 inch drop and one with a 2-3/4 inch rise or 4 inch drop. It also includes a 1-7/8 inch ball, 2 inch ball, hitch pin with...

  • Trailer Wiring for a 1992 Chevrolet Van
  • To get your 1992 Chevrolet Van wired to pull a trailer, I would recommend the T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector, # 118338. This will quickly plug into the existing wiring without splicing or cutting. You will need to remove the interior trim panels to install, but once installation is complete, the 4-way connector will simply rest in the cargo area when not in use. If you need to pull a trailer that has brakes, then you will need to first install the T-One...

  • Where Does the Trailer Wiring Harness # 118338 Connect to a 1993 Chevy Van
  • The Tow Ready custom fit vehicle wiring, # 118338, connects to the vehicle behind the tail lights on the 1993 Chevy vans. However, a conversion can take many forms and you might not be able to connect this harness in the same manner. I have included a link to the installation instructions for you to view.

  • Where Does a Trailer Wiring Harness Install on a 1996 Chevy Conversion Van
  • Directly behind the tail lights on a 1996 Chevy full size van is where you would plug in the trailer wiring harness # 118338. There should be connectors that will mate with the ones in the wiring harness. I have included a link to the installation instructions for you. On a conversion van, accessing the tail lights could be a little trickier than on regular models but it all depends on how the conversion van is equipped.
