1992 GMC C/K Series Pickup - Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector

  • Trailer Hitch Wiring
  • Curt
  • 4 Flat
  • No Converter

Quickly and easily install a 4-way trailer connector on your GMC C/K Series Pickup 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.

This rear bumper wiring harness allowed me to replace the original harness that had been butchered by no-strip squeeze connector that had rotted the wires. Absolutely worth buying. 678152

The wireing and connecter ' s are well made and the assembly is simple and straight forward. The ground screw isn't suitable for frame rail , I drilled 3/32 as recommended but screw broke.i went ahead and drilled to 1/4 and bolted ground wire. Delivery was ok except usps dropped the ball as usual. Good product will use them again. 313505

  • Parts Needed to Install Electric Trailer Brake Controller on 1994 Chevrolet Pickup
    If the 4-way trailer connector you have on the back of your 1994 Chevrolet truck needs to be replaced use Curt # C55315. There will be a connector under the rear of the truck on the driver's side to install the harness. Once you have the 4-way connector you can use our # ETBC7 kit to install the 7-way and everything you'll need for the brake controller. The Curt TriFlex Brake Controller # C51140 will hardwire in using the adapter # C51515. I've linked a video showing the TriFlex...

  • Parts Needed to Install Brake Controller on 1993 Chevy C/K Series Truck
    You're certainly on the right track, with a small exception or two. Instead of getting the # 37185, I'd get the # ETBC7 Brake Controller Install Kit. The kit includes the # 37185, plus all the hardware, wire and circuit breakers you'll need to complete the install. As for your brake controller choice, the # 39510 Voyager brake controller would be a good choice if you're very familiar with using and troubleshooting brake controllers. The Voyager doesn't use a digital display, and...

  • Installing a Hopkins Agility Brake Controller on a 1998 Chevrolet Pickup
    We have everything that you need to install your Hopkins Agility Brake Controller, # HM47294, on your 1998 Chevrolet truck. The installation process is going to depend on how your truck is currently equipped. If your truck has no trailer wiring at all, then you will need a few different components. First, you will need 4-way flat trailer connector. For this, I recommend the Curt T-Connector Harness, # C55315. This harness will plug into the factory connector located on the driver side...

  • Recommended Trailer Hitch for 1991 Chevrolet K2500 with a Regular Bumper and a 8600 GVW Package
    My contact at Curt said that the 8600 GVW package will not affect how the Curt Trailer Hitch # C15325 fits on your 1991 Chevrolet K2500. I recommend using this hitch because of how well Curt manufactures their hitches. The max Gross Towing Weight for this hitch is 16,000 lbs and the max Tongue Weight is 2,400 lbs. Keep in mind that you will need to know your vehicle's towing weight capacity. If your vehicle's towing weight capacity is less than the Gross Towing Weight of the hitch, then...

  • 4-Way Trailer Wiring Connector Recommendation for a 1988 Chevy Silverado
    I have a much easier solution for installing a 4-way on your 1988 Chevy Silverado 1500. What you would want would be the part # C55315. This plugs inline with the taillight connector on your truck and does not require any hardwiring. Otherwise you would need to test the wiring of your truck taillights with a circuit tester like part # PTW2993 to wire the 4-way you currently have to it. White wire would get grounded, brown wire runs to the wire that comes on with the running/head lights,...

  • Gooseneck Hitch and Wiring Recommendation for a 1994 GMC 2500 Truck
    The gooseneck hitch we offer with the best price that is confirmed to fit your 1994 GMC 2500 truck would be the Reese Fold-Down Gooseneck Trailer Hitch with Installation Kit # 8339-4440. I attached a link to the installation instructions for you to check out. For trailer lighting let's start with a 4-way, you may already have one. But in case you do not you would want the Curt Wiring part # C55315. Now to convert this to a 7-way you would want the Brake Controller installation kit part...
