  • CURT

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 and near the spare tire.


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 find what I was looking for, good prices, fast shipping, all combine to have me come back for all my trailering needs!!



by:
1991 Chevrolet S-10 Pickup

Great product, I installed it yesterday quick and easy without cutting into the vehicle's wiring harness. I gave it four stars because I did have to replace the eyelet on the white wire for a larger one in order to use the wiring harness body ground underneath the connector.

Simple plug & play installation, works like a charm.

All I could say is wow! In fact, I am so pleased I'll say it backwards, wow! I received my product sometime ago and did not install it till now. Having said that, the harness resolved all my issues immediately plug-n-play! Everything worked impeccably! All my frustrations eradicated within moments! Listen all, these products are unparalleled! The customer service exemplified and shipping times are unequalled! I am one content and happy customer and will definitely be back, as well as referring all my family and friends! Extremely high recommendation. Thank you etrailer!

This harness is better than the one piece design. If one of the connecters goes bad from corrosion or wear, they can be purchased separately and soldered together.

THis came in and it fit my 1989 Suburban perfect. The old one had some issues, and this new on cleared up my problems. Great product.

  • What is Needed to Install a Brake Controller on a 1986 Chevy Suburban
    To install a Tekonsha Prodigy P3 # 90195 on your 1986 Chevy Suburban you need to use a circuit tester to find the cold side of the stop light circuit (it only gets hot when you depress the brake pedal). According to my research it looks like you'll have to install all of your wiring and for that I recommend the following parts: - Curt 4-Way Wiring Harness # C55312 - Universal Wiring Upgrade Kit # ETBC7 - Prodigy P3 # 90195 Attached are the instructions for the P3 that aren't an exact...

  • Curt Class III # 13920 Trailer Hitch for 1997 Chevy S-10 SS Pickup With Roll Pan Bumper
    We do have a Curt Class III hitch, part # 13920 that's compatible with the roll pan on your S-10, as long as the roll pan is factory installed, and not aftermarket. The receiver opening would be concealed behind the license plate, so you'd need to cut a hole behind the plate. You might also need the following to complete your towing system: Trailer wiring harness, part # C55312 Ball mount, part # AMSC2 1-7/8 inch trailer ball, part # 19260 2 inch trailer ball, part # 63845 To view the...

  • Installing 7-Way Connector and Trailer Brake Controller on 1996 Chevy S-10 Pickup
    Since your 1996 Chevy S-10 already has a 4-Way connector in place the best way to convert it to a fully-functioning 7-Way is by installing the Universal Wiring Kit # ETBC7. This particular kit includes the 7-Way harness itself that will plug right into the existing 4-Way, plus all the additional wiring, circuit breakers, and quick-splice connectors needed to make this conversion and install a brake controller (which we'll get to later). I have attached the complete installation instructions...

  • Trailer Wiring and Brake Controller for a 1985 Chevy M1008 CUCV
    Assuming that the military version of the 1985 Chevy C/K series trucks has the same tail light configuration as the civilian models you would start by installing a 4-Way connector using # C55312. If it does not have the proper connectors for this harness you would just need to hardwire in a 4-Way using # 18252. Then to hardwire in a 7-Way and a brake controller you will need # ETBC7. I have included some links that show and explain the ETBC7 installation for you. For a brake controller...

  • Fit of Draw-Tite 75500 Class III Trailer Hitch on 1986 Chevy Suburban C20
    According to Draw-Tite, their # 75500 Class III hitch is a fit for a 1986 Chevy Suburban C20. If you'll be towing with the hitch, you can add a 4 pole trailer connector using part # C55312. I'd also recommend an etrailer ball mount kit, part # 989900, which includes a ball mount with a 3/4 inch rise or 2 inch drop, a ball mount with a 2-3/4 inch rise or a 4 inch drop, a 1-/78 and a 2 inch trailer ball and 2 hitch pins. A handy carrying bag is also included.

  • etrailer Trailer Hitch Fitment on a 1995 Chevy S-10 for Light Duty Trailer Towing
    Yes, the etrailer Trailer Hitch Receiver # e44KR fits your 1995 Chevy S-10 and is rated to tow up to 4,000 lbs with a 400 lb tongue weight. I really like this hitch because of the matte black finish that not only looks more rugged but is also more durable than the classic glossy black finish against road debris. The next thing you need for your towing setup you also need the Curt T-Connector Wiring # C55312 and mounting brackets # 18144 and # C57202. This gives you a way to place the wiring...

  • Recommended T-Connector Trailer Wiring Harness for 1997 Chevrolet S-10 4.3L Automatic Pickup
    We do offer custom-fit T-connector 4-pole wiring harnesses for your 1997 Chevrolet S-10 Pickup. You can use the Curt part # C55312, which will plug in without any cutting or splicing of wires to the connector located beneath your vehicle, along the driver's-side frame rail. Be sure to solidly attach the white ground wire's ring terminal to a clean bare metal surface on the truck. A proper ground is essential for correct operation of a wiring harness.

  • Will Curt Trailer Hitch C14082 Allow Stock Rear Tire To Be Installed On 1987 GMC C/K 1500 2WD?
    Since your 1987 GMC C/K 1500 Long Bed 2WD has the stock size spare tire, it can be reinstalled after installing the Curt Trailer Hitch Receiver # C14082. If you are looking to tow a trailer with your truck you will also need a vehicle wiring harness # C55312 and a ball mount, hitch ball, and hitch pin and clip which can be found in the etrailer Ball Mount Kit # 989900. I included a link to the written instructions of the # C14082 and a video reviews for the other products mentioned for...

  • Replacing 7-Way Trailer Connector On a 1991 Chevrolet Suburban
    For your 1991 GMC Suburban V1500 we have the Curt T-Connector Vehicle Wiring Harness # C55312 4-way flat connector that will plug and play into the factory connections. As there is not a 7-way connector with the factory connections you can use the Curt Trailer Connector Adapter # C57672 to tie into the reverse light and charge line wiring wiring on the rear of your Suburban. You will be able to connect the 4-way harness directly to the adapter to take care of the running lights, turn...

  • High Capacity Trailer Hitch for 1985 Chevy C/K Series Pickup
    The B&W BWHDRH25198 Class V hitch is indeed a fit for your 1985 Silverado. The hitch has a 16000 lb towing/1600 lb tongue weight capacity, which will be greater than the towing capacity of the vehicle, so so worries about the strength of the hitch. Assuming that your trailer has electric brakes, you'll need to install a brake controller to actuate them. I'd recommend the Tekonsha Primus, part # TK90160. The Primus is a proportional controller, which provides smooth, safe and predictable...

  • 4-Pole Wiring Harness Fit for 1986 Chevrolet K30 Military CUCV Pickup
    We can help you determine if the Curt # C55312 T harness will fit your 1986 Chevrolet K30 military CUCV pickup. If you review the linked photo of these harness' connectors you'll see what you're looking for on the truck. The connector you want to find has a square cross-section and should be located along the driver's side frame rail. If you truck has no connectors on the frame rail you can still wire in a universal-fit 4-pole harness like # 18252. This kit includes a circuit tester to...

    First, the pictures that you see are of the actual Draw-Tite trailer hitch, # 75500. If you click on the third picture, you will see that the mounting brackets on either side of the hitch are actually at an angle so the hitch will fit the angled frame on the vehicle. You can also see it in a diagram in the instructions I have linked for you to view. If you plan on doing some towing, I recommend the etrailer ball mount kit # 989900. It comes with 2 ball mounts, 2 balls, a hitch pin with...

  • 7-Way and Brake Controller Recommendation for a 1990 Chevy Blazer
    I have an easier solution installing trailer wiring and then a brake controller in your 1990 Chevy Blazer. You will need to start with a 4-way (if you do not have one). For that you would want the # C55312. 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 Brake Controller Install Kit and 7-Way Adapter part # ETBC7. I attached installation instructions and an install video for this product as well. For...

  • Trailer Hitch Recommendation for a 1992 Chevy S-10 with Roll Pan Bumper
    The Curt hitch part # 13920 is designed to fit the 1992 Chevy S-10 trucks that have the factory roll pan bumper. This hitch would fit behind the license plate so it sounds like this would be exactly what you would need. For trailer wiring you would then want the part # C55312. Since 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 or 4 inch drop....

  • Will C55312 T-Connector Vehicle Wiring Harness Fit 1984 GMC S15 Pickup
    To install a 4-way on your 1984 GMC S15 Pickup, you will need to hardwire a connector like Draw-Tite 4-Pole Hardwire Kit, # 18252. Just use the included tester to locate the vehicle's right turn signal, left turn signal, and tail light circuit. I have included a wiring chart and install video for you. Part # C55312 is designed for the 1985 to 1990 GMC S-15 pickup so this would not work for your 1984 model.

If you already have one you'll just need the Universal Installation Kit for Trailer Brake Controller # ETBC7. If you need to add a 4 pole as well, you can use the Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # C55312 to add one.
