Video Transcript for Hopkins Custom Fit Vehicle Wiring - Trailer Hitch Wiring - 30955 Review

Today we're going to review part number 30955. This is the Hopkins Replacement Multi-Tow 7-Way and 4-Way Trailer Connectors for the Ford, GM, Dodge vehicles with the factory 7-way. This is a custom-fit application. It applies to about 30 different vehicle applications that are equipped with a factory 7-way tow package. What I would recommend is to go to our website, use our fit guide, put in your year/model/vehicle and it will show if this will work for your application. This is a multi-tow connector, provides multiple towing options from the one connector. Again, provides the 7-way RV blade, the 4-way flat connector.

It is very easy to install. It's simple to plug in. There's no cutting, splicing of wire; save a lot of time. Plugs into the OEM connector. It helps create an exact fit and it gives you a maximum weather-proofing.

It's made of a durable plastic housing. It's very impact and corrosion-resistant. Again, it does include the dust covers. You can see the hinged cap over the 7-way to protect it and also the dust cover over the 4-way. It does come with the mounting bracket and the hardware to install the bracket to the connector and the hardware to install the bracket to the vehicle. This measures about 10-1/2" from the back here to the very end.

Basically, when you go to install this, what you'll do is go on to your vehicle. Different vehicles, this would be on just for an occasion; usually they're around the spare tire or on the driver side. You'll find a connector that probably has a plug just like this in it. It'll match, just pull that plug out of the factory, plug this into it. Go back to the back of the vehicle, take your mounting bracket.

Actually, probably before you plug it in you want to slide this over and then go ahead and plug this into the connector. Then just slide this up to the 4 holes lineup. Use the nuts and bolts to attach that. Then you have 2 holes up here. Use this bag to attach it to the vehicle. Very quick and easy installation. That should do it for the review on part number 30955. This is the Hopkins replacement multi-tow 7-way and also gives you a 4-way trailer connector here for the Ford, GM, Dodge vehicles with the factory 7-way. .

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! 676879

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. 454561

Nice replacement for factory plug. Did not use hardware supplied for installing bracket. Self tappers worked much better for me. Only reason I didn't give it 5 stars. 564276

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. 396795

I bought this style of Electrical Hitch tail light hook up by mistake, this one comes with a bracket and you can mount it in many places using the bracket. My Chevy Silverado has a twist on flange opening which takes a different style model. Returns you pay for shipping, which is not a big deal, but Just make sure when you plan to purchase an item that you buy what you need for your vehicle, etrailer has many models that can go with your vehicle, I just got in a rush, I ordered the correct model item with flange and will be returning this style but everything about this style is good so I rated it 5 stars. 505872

  • Does The 2018 Chevy Express Van 3500 Have Factory Wiring For 7-Way Plug
    The 2018 Chevy Express Van does have the brake controller wiring existing to wire in the brake controller if it has the towing package but that does not mean all of the wires are extended to the back of the vehicle. There may be a round plug with a cap inside your driver's side frame rail and if there is you can plug Hopkins 7-way plug # 30955 into the port for the 7-way. If there is not a round plug inside your driver's side frame rail then you may have a bundle of wires extended to...

    The Pollak 7- and 4-Pole Trailer Connector Socket w/ Mounting Bracket, part # HM40975 is designed to be a replacement for an OEM 7-way connector on the back of your 2006 Avalanche. If you have a 7-way connector on your truck and you want to replace it with a 4-way and 7-way, then this is the connector you need. If you are wanting to use the connector in your spare tire well I recommend part # 30955. I have attached a photo of the connector in the spare tire well that this harness connects...

These will attach to an existing US Car end wiring harness. If you don't have the harness, I recommend the Tekonsha T-One Vehicle Wiring Harness for Factory Tow...

  • Adding 4-Way or 7-Way to 2002 GMC Sierra 2500HD Without Factory Tow Package
    Though you may not have the factory tow package, almost all GM pickup trucks like your 2002 Sierra 2500HD came with the factory trailer wiring. You mentioned you have an existing trailer plug, which you can use to install the Multi-Tow 7-Way and 4-Way Trailer Connectors # 30955, which will plug into the OEM connector above the spare tire. I've added a couple links to video reviews for you to check out as well.

Under the hood there are the following fuses related to the tow package wiring: Location 8 = right stop lamp, trailer turn signal Location 16 = left stop lamp, trailer turn signal Location 35 = Trailer wiring (this is a very ambiguous description and just might be the culprit) Location 62 = Trailer wiring (see above) Oddly enough there...

It is easy to install and has a bracket included to mount the connector to. It is a confirmed fit for your truck. I've attached a video to assist.

    If the factory plug you are talking about on your 2003 Ford F-150 looks like the one in the picture I have included then # 30955 will fit. It is designed to fit the 1997 to current Ford trucks equipped with the factory socket in the picture. If your truck has square connectors then you would need to use a different harness, # 118242. I have included a link to a video showing a typical installation for you.

I will list the options below, so you can determine which will be the best option for relocating your connector to the bumper of your vehicle.

  • Recommended 5-Way Connector for 2012 GMC Sierra 2500
    We do have a trailer connector similar to the Hopkins # 30955, but with a 5-Way connection as well, with the Hopkins Endurance # HM48470. This particular connector features 7-Way, 5-Way, and 4-Way plugs. This issue is that this would need to be hardwired to the wiring on your truck, as there is not a custom-fit, plug-in model available. A better option for your 2012 GMC Sierra will be to use the Curt 5-Pole T-Connector Vehicle Wiring Harness # C56584 if you have the factory 7-Way. This...

  • Changing from a 4-Way Flat to 7-Way Blade Trailer Connector on Trailer and 2003 Ford Ranger
    First I recommend going with a 7-Way blade style for your trailer and truck because that is the most common advanced function connector used. To add one on the trailer you can use # PK12706. If your trailer only has the basic light functions then you will only need to cut off the 4-Way and attach the wires according to the diagram I have included. Please note that when you attach the existing wires to the connector you cannot just go by wire color. You will need to go by function in...

    I have a solution for you, and you will not need to cut into any wires. If you do not have a factory tow package on your 2010 GMC Acadia, you will first need to install a 4-way wiring harness. I recommend the Tow Ready T-One Vehicle Wiring Harness # 118451. This wiring harness will plug directly into the back of your taillights, into your vehicle's current wiring system. I have attached an installation video of this harness on a 2011 GMC Acadia. The wiring harness has a 4-way flat...

  • Installing Taillight Converter Tow Package Trailer Wiring Harness on 2000 Chevy Silverado
    Typically, your truck would have been equipped with tow package wiring that would have already been converted. It sounds like somebody's come along and messed with that. You can begin by checking for the original tow package wiring. Look for a wiring harness that terminates in bare wires located above the spare tire or on the driver's side frame rail alongside the spare. The plug you refer to won't be there, as GM didn't start using that until the 2003 model year. If the wiring is still...

  • Replacing a 7-way Trailer Connector on a 2006 Chevy Silverado
    The factory plug is located above the spare tire on your 2006 Chevy Silverado. I have included a picture of what it looks like and where it is located. You will probably have to lower the spare for easy access to the plug. The tow package wires will be bundled together in the same location as the factory plug if the factory plug is not present. There should also be a tag on the wires that lists the functions of each color wire. If there is no factory plug I would recommend using...

  • Adding a New 7-Way Trailer Connector to a 1992 Ford F-250 that Previously Had a 7-Way
    What you will need to do is test the plugs you have found with a circuit tester like # 40376 if needed. You will be testing for the various lighting functions, brake controller output (if still installed) and a good ground. If all the signals are there and working properly, you can hardwire in a 7-Way trailer connector. I recommend a multi-tow, like # HM48470, so you will have a 4-Way, 5-Way, and a 7-Way. What you will do is remove the plug on the end that works, clip it off, and attach...

  • Adding 4-Way Trailer Harness To 2013 GMC Sierra With Factory 7-Way
    To add a 4-way connector to your Sierra I recommend the Tow Ready T-One Wiring Harness, part # 118384. This plugs into the vehicle wiring under the rear of the truck by the bumper and allows you to retain your 7-way connector while giving you a 4-way as well. If you wish to change your factory connector to a 7-way and 4-way combined the connector I recommend for your 2013 Sierra is the Hopkins Multi-Tow 7-Way and 4-Way Trailer Connector, part # 30955.

The connector would plug into an existing connector located at the rear of the driver's side frame rail behind the back bumper or above the spare tire as shown in the photo I provided. Unless it was equipped with a rare factory tow package, it is unlikely your Blazer will have that connector. If you're wanting to install the 7-way to tow a trailer equipped with electric...

    There are a few troubleshooting steps to help you figure out why you have no power. I would start by making sure that there is not any corrosion or debris blocking your connection points. If they are clean or still no power after cleaning, I would check your grounding connections. Make sure your grounds are firmly connected to a clean, bare metal surface. Next, test the pins on the connector where the wiring harness plugs into the truck using a circuit tester like Item # 40376....

    You are entirely free to choose an alternate mounting location for your new 7-way as long as your factory wiring harness can still reach its location. Your vehicle and trailer will not care on which side of the hitch their electrical connection is made. I do suggest you first make certain that your trailer connector can reach your new preferred location on the vehicle when the trailer and vehicle are hitched. You also need to be sure the OEM harness on the vehicle (with the round U.S. Car...

Refer to the diagram attached below to place the wires in the correct position. Check out the video linked below for more details.
