Video Transcript for Trailer Wiring Harness Installation - 2005 Chevrolet Silverado

Today on our 2005 Chevrolet Silverado crew cab, we're going to install part number 30955. This is a replacement multi-tow 7-way and 4-way trailer connector. We're going to replace the original 7-pole connector That came with the vehicle. This is how it came to us, so you can see that the connector has seen better days. To remove our 7-pole connector, there's a tab right here that we push down and pull out. Sometimes there may be a little gray tab or a lock that fits around this.

You just push down in the center of it and just push it out of the way, then put it back when you're done. We don't have that one, so we'll just push down on this tab and pull it apart. This is our new part that's going to replace the OEM connector. This will simply just plug right back in, like this. However, we're going to take this and route it down towards the bottom of our hitch, toward our pre-existing mounting bracket. This is the bracket that comes with the part.

However, we're going to use the pre-existing one. A good location for this if you wanted to install it, would be right here. It does come with the hardware to install the bracket. However, self-tacking screws will work best in this application here. Let's go ahead and route our wire harness down.

Before we add our new connector, we'll go ahead and put some dilectic grease on the contacts to help protect them. We're using part number 11755. Let's go ahead and route this through our bracket. We'll go ahead and make our connection. We'll just push the two together, make sure they line up OK, and squeeze them until they click. Now we'll use the hardware that comes with the kit, to attach our 7-pole to the bracket.

With our hardware loosely assembled, we'll go ahead and tighten it down, using a flat-blade screw driver. Typically, this star washer on the back will give enough grip; we don't need a wrench. If you do, a 3/8 will work just fine. We'll go ahead and route our wire harness up and out of the way, make sure it's safe and secure with some zip ties. Zip ties don't come with the kit, so you might want to go ahead and get extra long zip ties to go around the hitch. In just a few minutes we've got a new 7-pole connector plus a 4-pole connector installed on our truck. That will do it for our replacement multi-tow 7-way and 4-way trailer connector on our 2005 Chevrolet Silverado crew cab. .

Replacement Custom Multi-Tow 7-Way and 4-Way Trailer Connectors - 30955

Average Customer Rating:  4.7 out of 5 stars   (362 Customer Reviews)


by:

etrailer had what we needed. At times it is not easy locating accessory parts on vehicles not factory installed. Easy to navigate site to find and compare the exact parts we were looking for.



by:

Looks like a good quality plug, the only thing I can knock it for is there’s no bracket for securing it to the round tube on the receiver.



by:
2014 Jeep Grand Cherokee

Product was exactly what I was looking for and thanks to the hitch system previously purchased, it was fabricated for a perfect fit. Also, the first one that came in was busted up a little, etrailer immediately sent a new one out with no hassle. Great company.



by:

Perfect fit just plug and play good quality hitch.



by:

Great fit works good has 7way rv plug and the regular flat 4 plug no need for adapters to lose or have stolen.

Been using this plug for a year now still working great



by:

The Curt Trailer Hitch Receiver was easy to install and has worked just fine in pulling my several trailers. For the price, an excellent deal. The 7-Way and 4-Way Trailer Wiring Harness Connector by Hopkins was a disappointment because the cap that doubles as a dust cover and latch to the adapter has come off and missing after a few months. This cap is not replaceable, the whole connector would have to be replaced.

Exact fit for my 06 GMC Sierra it took longer to get my spare tire down than to install the tow package. My spare was stuck.



by:

Perfect fit and function as usual from etrailer.



by:
2004 Chevrolet Silverado

Perfect! I used this on a single cab Chevy Silverado 1500. Plugged into factory trailer lights near spare tire, mounted it up, plugged in trailer and everything worked just like it should. My truck does not have a spare tire so I removed the spare tire keyhole mount and cut some of the bumper to fit the adapter. My truck did not require a ECM/PCM flash of any kind, although I hear some vehicles may have to.



by:

I installed this today. Took around 90 minutes but part of that was learning how to get the spare out of the way. I drilled two holes in the bottom of the bumper because of where I wanted the connector to be placed. All necessary hardware came with the unit. This was very easy to do after watching etrailer's How To video. Good job guys, great product.

in my case I have to say that first look at YouTube from there I got the video with the description of the process and the number of the part of there just went to etrailer.com I put the # alone went out it was really easy to send fantastic just wait 4 days in regular shipment for the installed only you see that plug it in thank you I hope that some more will serve..



by:

Nice product ,Easy to install and then worked as supposed to . I installed in bumper as opposed to the add on bracket that came with it ,made for a easier way to plug in trailer cord.

I bought this 7 way trailer connector to replace a broken one on my 2006 Chevy 2500HD. It was an easy install and only took a few minutes to complete. I tested it with my trailer connected and all works fine.
The shipping was super fast.
Thanks , etrailer.



by:

Works great!!! Thanks....



by:

Cathy T. was very good help. She set me up with the correct parts for our 2001 Chevy so we can have a 7 prong plug in at the bumper and in the box.
We got rid of the cobbled up mess that started giving us trouble and now everything works great. The plug and play took me about 1 1/2 hours to complete. We will do business again if needed. Thanks again Cathy T. and etrailer!



by:

The product was an exact one-for-one replacement. However, I ended up having to replace the female connector due to corrosion. This took a bit of time. The result was all new connections that work fine. Thanks for all your assistance.

2007 Chevrolet Silverado

My 2007 Classic Silverado Crew Cab 4x4 did not have a factory hitch receiver, so I selected the 13322 Curt Hitch Receiver because it closely resembles the OEM hitch receiver and attaches to the bottom of the bumper. Installation was easy, as shown in the videos and described by other reviewers. All holes aligned perfectly. I did not remove the spare tire as it is not necessary. I used two jack stands to raise/support the receiver frame in place while I started the first bolts. I had the 22mm and 19mm sockets needed to tighten and torque the bolts/nuts. It looks great and I now am able to tow.

For the wiring I installed the 30955 Hopkins 7-Way and 4-Way Trailer Connectors to the bumper adjacent to the license plate. This required drilling a 2-1/8" hole in the bumper, which was time consuming, but it now resembles a factory installation. I was able to remove the license plate and connect to the factory plug.

I ordered these parts from etrailer for a number of reasons: 1) The website is intuitive and contains a tremendous amount of information for the person who is trying to research product information; 2) the selection and inventory is amazing; 3) the prices are very competitive – free shipping for orders over $99; and 4) the dedicated customer service is outstanding – the email communication is prompt. I ordered on a weekend and it was delivered by the following Friday.
A very positive first experience.



by:

Quick shipping. And best part they sent me the correct hitch and plug in. No complaints here!

  • Wiring a 7-Way Connector from a 4-Way
    Yes, you will need to cut off the 4-way connector from your trailer and wire the 5 wires to a 7-way connector like # PK12706. Test the function of the wires before connecting them to the 7-way. Refer to the diagram attached below to place the wires in the correct position. Check out the video linked below for more details. If you need to add a 7-way to your vehicle as well, let me know the year, make, and model on your vehicle and any existing connectors you have, and I can make a recommendatio...

  • Can Redarc Tow Pro Liberty Brake Controller Install in 2017 Chevy Express Van 2500
    The Redarc Tow Pro Liberty part # RED24FR can install in your 2017 Chevy Express Van 2500 with the universal install harness # RED69FR. Your vehicle has the blue output brake wire already ran from the back to the front. It is located under the dash near the emergency brake pedal. If your vehicle has a round plug with a cap inside the driver's side frame rail instead of a bundle of wires in the jack storage compartment, use part # 30955 to add the 7-way.

  • How to Replace the Factory 7-Way on a 2006 GMC Sierra 2500HD with No Connector
    Yes, you are exactly right. The Curt Universal Wiring Harness part # C56229 has the same US car connector that would have came on your 2006 GMC Sierra 2500HD from the factory. The female end of this connector will plug right into the male end on the Replacement Custom Multi-Tow 7-Way and 4-Way Trailer Connectors part # 30955. In order to join the blunt cut wires on your truck to this harness I recommend using part # DW05744-10. These connectors are made of heat shrink which will help keep...

  • What Circuit of 2015 Chevy Silverado Connects to Trailer Battery
    The 1:00 pin of the 7-way at the rear of your 2015 Chevy Silverado is the circuit that would connect to and charge the trailer battery. On a Silverado like yours this circuit can sometimes not be active but with a few connections under the hood the circuit will be active. If you check out the attached help article you can see how this connection would get made on a truck like yours.

    The Curt Custom Wiring Adapter for Trailer Brake Controllers - Dual Plug In # C51451 is a fit for your 2018 Chevy Suburban if you already have the factory tow package with the factory 7-way trailer connector. If you do not have the factory 7-way, then you will need the Replacement Custom Multi-Tow 7-Way and 4-Way Trailer Connectors # 30955 and will hardwire the wires present under your dash to the Universal Wiring Adapter for Curt Trailer Brake Controllers # C51515.

  • Recommendation For Replacing Cover On Vehicle 7-way Connector
    I have a complete replacement option for you, but unfortunately the cover for your 7-way connector is not something that is available by itself. Instead I recommend using the # 30955 you were looking at to replace the connector. You will just need to undo the 4 perimeter screws and unplug the connector on the back, then reinstall the new connector. I included a video of the # 30955 for you to take a look at.

  • Trailer Hitch for Towing with a 2012 Chevy Tahoe
    The only trailer hitch that was designed for your 2012 Chevy Tahoe is the Curt Trailer Hitch Receiver # C13161. The Ultra Frame Trailer Hitch Receiver # 41947 is a pretty big hitch that is designed for a 2012 Chevy Silverado 3500 cab and chassis model which is pretty different to what you have. With that being said, it looks like your Tahoe has a towing capacity range of 5,200 lbs - 6,000 lbs so since the Curt is rated for a max of 6,000 lbs you will be able to tow with your Tahoe to it's...

  • Recommended Multi-Tow 7-Way and 4-Way Trailer Connector for a 2008 Chevy Silverado
    By the term pre-wired, do you mean that you have a factory 7-way on your truck? If so, you will actually need the Replacement Multi-Tow 7-Way and 4-Way Trailer Connectors for Ford, GM Trucks with Factory 7 Way, item # 30955, for your 2008 Chevy Silverado. This is the connector you can use to plug directly into your vehicle wiring and replace the 7-way you currently have. You would also have the option of using a standard 7 to 4-Way adapter, like part # PK12716. If you go to the provided...

    Thank you for all of the details. If the Curt T-Connector C56366 (discontinued) for your 2011 Honda Pilot is only showing 1 light on your Hopkins Tester/Adapter # 47345 with the trailer plugged in then either the tester/adapter is malfunctioning or your Curt wiring harness is malfunctioning. If you have a circuit tester then I recommend using that instead to test your Curt T-Connector or you can either plug a trailer that has a 7-Way into the Curt connector or use the Hopkins adapter...

    Brake controllers like the Tekonsha Prodigy P2 Trailer Brake Controller - 1 to 4 Axles - Proportional # 90885 are not vehicle specific fits. This controller will absolutely work with your 2008 GMC Sierra 1500 extended cab. No plug is present under the dash, but the wires are already run for you under the dash.

  • Recommendation for a Brake Controller to Fit a 2009 Chevrolet Tahoe
    Depending if you already have a 7-way connector installed or not on your 2009 Chevrolet Tahoe will determine the amount of additional parts that will be needed when installing a brake controller. First, the Tekonsha BRAKE-EVN # TK63VR, that you referenced is a quality controller that will work well with your Tahoe. If you already have a 7-way trailer connector installed on your Tahoe, then all you will need is this brake controller and the included wiring harness. The needed wires to...

  • 7- and 4-Way Trailer Connector for a 2012 GMC Sierra 2500
    Yes, Curt 7- and 4-Way # C57101 will plug into the same harness as the factory 7-Way on your 2012 GMC Sierra 2500 (though it will not fit in the same place). For a 7- and 4-Way without backup alarm you could use # 30955 or # HM40975.

  • 7-Way to 6-Pole Trailer Connector Adapter for Horse Trailers
    Most horse trailers have a 6-pole trailer connector. In order to attach the 6-pole trailer connector to your vehicle then you will want to use the Hopkins Heavy-Duty, Coiled Trailer Connector Adapter part # HM47083 if the center pin on your vehicle connector is for 12v power or part # HM47085 if the center pin on your vehicle connector is for the brake circuit. You will need a 7-way connector on your vehicle in order to activate the trailer brakes on your horse trailer. If you do not...

This combination 4-pole/7-way trailer socket will plug right in to the round U.S. Car Connector if present. The blue brake output wire will already be present; it runs from the 7-way up to the dash near the emergency brake pedal. The blue vehicle wire connects to the blue wire on the P2.

  • Troubleshooting Motorhome 7-Way Trailer Connector
    I recommend checking your fuses on your motorhome first. If your fuses are good, then use a circuit tester like # PTW2992 to test the wiring. I recommend checking right behind the 7-way first as sometimes that connection goes bad or the inside of the trailer connector itself. Next trace the wiring as needed to find where the power for each function broke down.

If you don't have the factory tow package then you might need the additional wiring part # 30955.

Your 4-way is not missing anything either. The fourth pin is actually a female pin so it's totally fine.

    I'm not entirely clear on what you've got going on, but I'll begin with some assumptions. It sounds like you have the lighting circuits working correctly, but you're not getting any power on the black 12-volt battery feed or the blue brake controller output wire, is that correct? You're installing a 7-way trailer connector, correct? The black wire should be ran to the positive battery terminal with a 40A breaker like # 9510 installed inline.

  • Recommendation for Upgrading to 18K Trailer Hitch on 2006 Chevy Silverado
    Going to an 18,000 pound rated trailer hitch on your 2006 Chevy Silverado 3500 will indeed require you to switch to a 2-1/2 inch receiver. This is not a problem though because as you mentioned we have various adapters available such as the Curt # C45405 that will reduce this opening to 2 inches so you can continue to use your existing accessories. Because the sleeve slides into the hitch receiver it won't restrict the use of your accessories at all in terms of capacity or function and it...

You will simply connect the adapter to the existing 4-Way on your Silverado and it will give you a 7-Way to hook up with the trailer. The additional wire leads will not be needed.

Both of these replacement parts install using a round 7-pin U.S. Car connector that plugs in to the back of the socket.
