Quickly and easily install a 4-way trailer connector on your vehicle with this custom harness. T-connector plugs directly into existing wiring - no cutting, splicing or tapping required.


Features:

  • 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
    • Locate connection points behind rear bumper
    • Plug in T-connector
  • Comes with dust cap for 4-way flat connector
  • Limited 1-year warranty


Installation

This custom-fit T-connector plugs into your vehicle's wiring harness, which is located behind the rear bumper, along the driver's-side frame rail.


Once installation is complete, the 4-way connector will be stowed beneath your vehicle, near the trailer hitch. A mounting bracket (sold separately) is recommended to keep the connector secure.


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 to install with no cutting or splicing of wires

The wiring harness plugged in easily and worked the trailer lights perfectly. There is plenty of wiring length to reach the rear bumper and stay up out of the way. A perfect add-on to any trailer hitch purchase.

No problems with the wiring ever. Still working great when pulling my trailer.

by:
This will be such an easy product to install. I bought this for my 2000 chevy s10 zr2 after picking a hitch from another truck in my local junkyard. I am waiting to install until I get the hitch put on but it will not take more than 5 minutes to complete.

Etrailer has wonderful customer service and ensured that I received my product. Would recommend this product and company to anyone.

Keep up the awesome service!

Still works just fine! I still use it all the time! Still happy I got this instead of manually soldering the wires together. It is well worth the time you save. I have been troughbqll the different terrain and car washes and it still puts out clean signal. Would buy again but i wont have to at this rate!

by:
This harness was easy to install. I did not have to cut existing wiring. The L mounting bracket holds the pigtail securely. And this is the company to buy from. They sent me an email a year later asking how the product was. What company does that these days? Will recommend this company and use them again.
by:
Easy install. Durable. Applied dielectric grease to all connectors for easy installation and corrosion protection.

great

Fantastic wiring kit installs in about 10 minutes with only a ground screw hole to drill. Just what I needed for my 2000 S10 pickup. As usual etrailer delivers quickly.
by:
etrailer is the first place I look for anything to do with trailering. The demos are great, the service is great, the prices aren't extortionate (which is also great) and there are choices. Been here before, will undoubtedly be back.
by:
2003 Chevrolet S-10 Pickup
Very fast shipping and the product was great. It took me longer to drill the hole for the ground screw then it did to hook the wiring harness up.
by:
2003 GMC Sonoma
All the product that have ordered from etrailer have been excellent . The service and shipping is also excellent. Great Company.

Installed trailer wire jumper in less than five minutes. Plenty of wire length. Installed in a 2000 Chevy S10. Just like factory install.

I have ordered stuff from here before and always got super fast shipping. Great prices on the products. The products have worked great for me which is several different products. Will continue to do business with etrailer. A+++++ rating in my book. Cant say enough about them.

The wiring looked just like the factory wiring and plugged right in with no hassle. All I had to do was drill a hole for the ground screw that was provided. Very pleased with the quality.

This was amazingly easy. Unsnapped plug on truck, plugged in new harness and installed ground. Worked perfect in 5 minutes no exaggeration.

I just received my order and now I don’t get a day off for 6 weeks having to work 12 hours a day.Never thought it would take so long .

  • Recommended Hitch for a 2002 Chevy S-10 Extreme that Mounts Behind the License Plate
    Thanks for the picture! For your 2002 Chevy S-10 Extreme, you will want the Curt Trailer Hitch item # 13920. This hitch is custom fit and bolts to your S-10 with included hardware. Since your truck has the factory roll pan bumper this will mount the hitch behind your license plate. The Curt Trailer Hitch item # 13920 is a class III hitch with a 2" receiver. It has a 3,500 lbs towing capacity, and a 350 lbs maximum tongue weight. This hitch is made in the USA and weighs 27 lbs. If you...

  • Trailer Wiring Options for a 1998 Chevy S-10
    Based on what you described it either sounds like your truck is wired differently than normal (which is highly unusual) or you are looking at the wrong connectors for trailer wiring. The part # 118359 should be the correct fit. But if the connectors are truly different you could just hardwire the 4-way with part # 18252.

  • Hitch Recommendation for a 2002 Chevy S-10 Extreme with Roll Pan Bumper
    The Curt Hitch part # 13920 has been confirmed to fit your 2002 Chevy S-10 Extreme with a roll pan bumper. 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 clip, and a storage bag. If the ball mount kit does not have the right rise or drop to tow the trailer level,...

  • Recommended Hitch for a 2003 GMC Sonoma w/ a Roll Pan
    Since your 2003 GMC Sonoma has the roll pan, the correct hitch for your truck is the Draw-Tite Trailer Hitch item # 75085. This hitch is custom fit and bolts to your Sonoma with included hardware. If you are planning on towing you will also need a wiring harness item # C55359 and a ball mount kit item # C45534. I also recommend using the No-Drill Mount Bracket item # 18136 and the item # C42CR to secure the 4-way connector to your hitch. This will put it in an easy to reach spot and...

  • Difference Between Curt and Tow Ready T-Connector Wiring Harness with 4-Pole Flat Trailer Connector
    Both 4-pole wiring harnesses available for your 2000 Chevrolet S-10 Pickup, Curt # C55359, and Tow Ready # 118359, are custom-fit types that plug into connectors on the vehicle. Functionally speaking there is no difference between the two. Most of the harness is manufactured by the same company. Other than the way the harness is spliced together they are pretty similar. The Tow Ready is more popular with our customers, probably because it is less expensive. I have attached the installation...

  • Trailer Hitch Receiver to Fit 2004 GMC Sonoma Crew Cab SLS
    The Draw-Tite Max Frame # 75085 is confirmed to fit your 2004 GMC Sonoma Crew Cab as long as you have either the factory step bumper or non-towing bumper. If your truck has the factory roll pan bumper then the Curt # 13920 is the correct hitch. If you're going to be towing with your truck you may also need wiring for your trailer's lights. The Curt Wiring Harness # C55359 will provide a 4-way trailer connector. This installs by plugging into your truck's wiring behind the rear bumper,...

  • Installation of Draw-Tite Hitch Receiver on 2003 Chevy S-10
    To install the Draw-Tite # 75085 on your 2003 Chevy S-10, you'd need to temporarily remove the bumper/fascia, and then bolt the hitch between the frame and bumper brackets. You will then reattach your bumper/fascia and the receiver will be under the license plate. If you are going to be towing you'll need a 4-way connector, the Curt # C55359; and I also recommend checking out Ball Mount Kit # 989900, which will fulfill your towing needs in one tidy package; a pair of ball mounts to give...

  • Compatibility of the Curt Class III Hitch # C13021 on a 1999 GMC Sonoma w/ Factory Step Bumper
    If your 1999 GMC Sonoma has the factory step bumper, then the Curt Class III Trailer Hitch, # C13021, is a confirmed fit. This hitch is custom designed to fit your vehicle and install with no drilling necessary. If you looking to tow a trailer, then I recommend the Curt T-Connector Vehicle Wiring Harness, # C55359, if you do not already have a 4-way trailer connection. I also recommend the ball mount kit # C45534. It comes with 2 ball mounts; one with a 3/4 inch rise or 2 inch drop...

  • Availability of Trailer Hitch for 1998 Chevrolet S-10 pick with the Extreme Kit
    From my research it looks like the 1998 Chevrolet S-10 pick with the Extreme Kit comes with a roll pan bumper. If that describes your vehicle then we do have a class III trailer hitch for you. Take a look at part # 13920. I have included a link to the installation instructions for you. 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...

  • Which Curt Class III Hitch Fits a 1999 GMC Sonoma
    We have a Curt Class III hitch available that will fit your 1999 GMC Sonoma but the part # C13300 is not a fit for it so I would instead recommend you the part # 13920 which is a confirmed fit that would work well. For trailer wiring you would then want the # C55359 which is also a confirmed fit. If you wanted to do 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...
