Hopkins Custom Fit Vehicle Wiring - 41125

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 or splicing 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
    • 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
  • 90-Day limited warranty


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.

Exactly what it looks like. Extends the 4 pole connector from the factory underbed location on the GMT 400 trucks. Very easy install. 271226

Everything you need to connect this is in the package. The light kit itself, the zip ties, the dielectric grease, etc. If you intend to connect the ground, you may need to have a drill available. The screw to secure the ground pin was also connected. Excellent product that I would highly recommend to anyone needing it. 414117

This was what we needed to wire up my buddy's truck for trailer lights. The only issue we had was the pins on the male side of the plug were not centered in the connector, so we adjusted them to the center with a small screwdriver. After doing that the connector fit the existing connections on the truck. All in all it was a very easy installation. 426970

Works good my old man kept splicing wire harness for is trailer light so I just orders from these guys and came in the mail a couple days after that. Literally only took 5 mins to install it a plug and play pretty much just have to hook ground to frame. I would recommend this for any vehicle because you have no splices and every thing is water tight. Work good you live where they lay a lot of salt down in Winter time. 415453

Thanks for the concern. All is well. I am a “rookie” when it comes to Boat and Trailer wiring. I have learned a great deal this past year... mostly from the many mistakes I have made. However it has been enjoyable and self rewarding.

  • 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...

  • 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...

  • 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...

  • 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...

  • 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...

  • 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....
