Video Transcript for Trailer Connector Socket Installation - 2006 Chevy Silverado

Today on this 2006 Silverado 1500 were going to install 40975 from Hoppy, and our bracket will simply bolt on to the bottom of the bumper at this location right here. So what we need to do is pull out the wiring harness from the vehicle that is stored above the spare tire, and its got plenty of lead, you just got to pull it out. We are going to leave this alone for now, and we are going to go ahead and mount our bracket to the bumper. It comes with two self tapping screws. Okay right now we will take our wiring harness, remove the cap and we will take our plug and just snap it into the bracket, and then make our connection behind it. And with that were already done.

There you have it for part number 40975 from Hoppy. .

Nicely built, durable This 4/7 pin dual connector was just what I needed. A good quality piece. Once you have one of these you will never settle for having a pigtail hanging off the back of your truck again. But a word of advice--if your vehicle doesn't have the mating 7-pole connector to connect to the back of this unit, buy the pigtail harness PK11998 to go with it!3113

I broke the factory plug and dust cover on my 2004 Silverado, when I backed it into a trailer tongue. So I thought I would replace it with a plug with both 4 way and 7 way receptacles. This was a perfect fit to the factory connector. I just used an angle grinder to remove the bent factory mounting bracket, and installed this bracket about the same place. Total time 15 minutes, including cutting off the factory bracket.13635

This is a great idea. I want to be able to use either type of plug--this does that. But I'll have a big hassle mating up the other side. I'm looking for a connector or else I'll have to solder and carefully shrink wrap all the connectors. it would be great if a pig tail was provided. It is designed for OEM applications for Ford Dodge and GM. I am putting it on a Volvo 240 Wagon. Most of the time I pull very small boat trailers. I have one bigger trailer that is 1900 lbs and wired with a 7 prong connector so I can use utility lights and trailer backup lights. This is a very nice quality connector. I just think it is STUPID not to sell it with a wiring pigtail.18334

On most trailers, the lights ground through the mounting studs. Make sure that at each ground location, there is no dirt or corrosion.

  • How to Install A Brake Controller On A 1997 Chevrolet K2500
  • Some models of the 1997 Chevrolet K2500 do have the brake (blue) and hot lead (orange or red) wires already ran from under the hood to the end of the driver's side frame rail.

To install a brake controller on your 1997 Chevrolet K2500 you will need to have a 4-way trailer connector on the rear of your vehicle and then you will need to hardwire the brake controller with the Brake Controller 7 & 4 Way Installation

  • Can the Power Wire on my 7-Way Connector Power the Automatic Open Function of my Tonneau Cover
  • Typically 7-way connectors that are hard-wired are run through a 40 amp circuit breaker to protect the circuit.

Also, you should check to make sure there is some kind of circuit protection (fuse or circuit breaker),

  • Brake Controller Not Working And No Power To 7-Way Connector On A 2005 GMC 2500 HD 4X4
  • I think your problem is in the power distribution box, under the hood, on your 2005 GMC 2500 HD.

The power post closest to the firewall of the vehicle should have a wire attached to it that will connect to the black power wire on the rear of the brake controller and a 30 amp fuse installed next to the post. The power post closest to the front of the vehicle should have a wire

  • Troubleshooting Turn Signals, Brake Lights Not Working with Running Lights On on a 2006 Silverado
  • It sounds as if you have a classic ground issue. When the vehicle running lights are on, and the brakes and or turn signals are activated, the amperage draw is the greatest and the faulty ground shows up. I would start with checking all of the ground connections on the trailer.
