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
    • Locate connection point at the rear of your vehicle
    • Plug in connector
  • Protective connection terminals resist corrosion
  • Comes with dust cap for 4-way flat connector, cable ties, and terminal grease packet for electrical connections

Installation

This custom-fit T-connector plugs into your vehicle's factory tow package wiring harness, which is located either behind your rear bumper or inside the frame channel on the driver's side.


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.

  • Will Hopkins 4-pole Wiring Harness 41125 Fit 2000 Chevrolet C3500 1-Ton Pickup
    Yes, you can use the Hopkins 4-pole wiring harness # 41125 on your 2000 Chevrolet C3500 1-ton pickup. This custom-fit part is made to directly fit your existing factory wiring, no cutting or splicing required. Be sure that the included ground ring terminal is tightly affixed to a clean bare metal spot on the vehicle. It is never a bad idea to apply a bit of sandpaper to the grounding point to expose clean bare metal; do this before you apply the included dielectric grease which provides...

  • Needing a Wiring Harness Adapter to Hook a 1997 Chevrolet 1500 Truck to Trailer Lights
    For your 1997 Chevrolet 1500 truck, I recommend the Hopkins Plug-In Simple Vehicle Wiring Harness, # 41125. This harness will quickly install on your vehicle using a simple T-connector to plug into your OEM wiring. You will not have to cut or splice into your existing wiring. I also recommend using dielectric grease, # LT37534, when installing this wiring harness. Just a apply a small amount in each of the harness's plug end prior to installation. The grease will help prevent electrical...

  • Location to Connect 4-Way on 1994 Chevy Blazer
    According to a pair of manufacturers I checked with, your 1994 Chevy Blazer will have a t-connector beneath your Blazer along the driver's-side frame rail. So long as your '94 Blazer is a full-size, this will allow you to use the Hopkins Plug-In Simple Vehicle Wiring Harness # 41125 or Curt T-One Vehicle Wiring Harness # C55319. Your Blazer must be a full-size though; if it is not there isn't a wiring harness available.

  • Brake Controller Recommendation for 1992 Chevy Suburban
    You will need to start with a 4-way (if you do not have one) on your 1992 Chevy Suburban. For that you would want the # 41125. 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 a brake controller I would recommend the Prodigy P2 Brake Controller part # 90885....

  • Recommended 4-Pole Trailer Connector for 2000 GMC Safari Van
    To install a 4-pole trailer connector on your 2000 GMC Safari, you'd use part # C55411. Installation would be pretty simple, as there is a wiring harness that ends in bare wires located in the jack storage compartment in the cargo area of your van. The harness is covered in wire loom, and the ends of the wires are likely wrapped in electrical tape. The wires would connect to the # C55411, color for color. For a more secure connection, I'd recommend using butt connectors like part # 05731-5...

  • 7-Way Trailer Wiring Connector Recommendation for 1996 Chevy Suburban
    To install a 7-way on your 1996 GMC Suburban you'll need to first install a 4-way like part # 41125 to give you the taillight circuits. Then to convert to a 7-way all you need to do is plug this 4-way into the # 37185 and you'll have a 7-way with the taillight circuits active. If you do have trailer brakes you would need the # ETBC7 instead of the # 37185 and a brake controller. This kit comes with everything needed to wire up the 7-way and install a brake controller. For a brake controller...

  • Recommended Brake Controller And Wiring For 1997 Chevrolet C/K Pickup Truck
    The brake controller I recommend for your 1997 Chevrolet pickup is the Tekonsha P3 # 90195. This is a proportional brake controller that applies the brakes in direct proportion to the braking action as the truck. This unit will work with electric or electric-over-hydraulic brakes. If you do not have a trailer wiring harness on your truck, you will need to first install a 4-way trailer harness and then a 7-way harness. For a 4-way harness I recommend part # 41125. You simply plug this...

  • Trailer Hitch Receiver, Wiring And Brake Controller For a 1990 Chevrolet C/K Pickup With Step Bumper
    I recommend the B&W Heavy-Duty Trailer Hitch Receiver # BWHDRH25124 for your 1990 Chevrolet C/K Pickup. This receiver requires no drilling into your frame to mount and has the added benefit of separate bolt on mounts to make installing easier with one person. The receiver has a maximum tongue rating of 1,600lbs and trailer capacity of 16,000lbs with or without a weight distribution hitch. The receiver has a tab to make mounting the 7-Way # ETBC7 easier on your truck. This will allow you...

  • Trailer Wiring Harness to Install Hayes Brake Controller on 1996 GMC K1500
    For the Hayes Energize XPC brake controller the wiring harness that connects into the wiring of your 1996 GMC K1500 is # HA81789-HBC. It needs to be hardwired into your truck with the black wire going to 12 volt power, white to ground, the blue goes to the rear of your truck to power the trailer brakes, and the red connects to the stop light switch which is the wire coming from the truck's brake pedal connector that is hot only when the pedal is pressed. You can test this with a circuit...

  • Brake Controller Installation on 1995 Chevy C/K Truck
    It sure can. A brake controller isn't a vehicle specific item. You can install a brake controller on just about any vehicle with a 12-Volt electrical system. However, I'd recommend going with the # TK63VR brake controller instead. It's at the same price point, and it's a proportional controller. A proportional controller uses an internal accelerometer to send the proper amount of voltage to the trailer brakes so the vehicle and trailer brake at the same rate for safe, dependable and predictable...

  • Trailer Hitch Fitment for 1998 Chevrolet C/K 1500 Pickup Truck
    Yes the discontinued Curt Trailer Hitch 37069 will fit on your 1998 Chevrolet C/K 1500. It will require drilling to be installed. I recommend the Curt Trailer Hitch Receiver # C14081 for you as this will allow you a no drill installation. This hitch is designed to work with the standard or step bumper on your year truck. If your Chevrolet has the roll pan rear bumper the Curt Trailer Hitch Receiver # 13942 will be the correct hitch. The Hopkins Plug-In Simple Vehicle Wiring Harness...

  • Trailer Hitch Receiver Compatibility For a 1996 GMC Sierra C/K Pickup
    The Curt Trailer Hitch Receiver # C15325 is confirmed to fit your 1996 GMC Sierra XLE as long as you have either the standard or step bumper. It will not fit if your GMC has a roll pan, or deep drop bumper. For a deep drop bumper Curt Trailer Hitch Receiver # C15317 is the one I recommend. The Curt Trailer Hitch Receiver # 13942 will fit with a roll pan rear bumper of 1500 series trucks. You will need a Hopkins Plug-In Simple Vehicle Wiring Harness # 41125 to give you a 4-way flat...
