Video Transcript for Hopkins Custom Fit Vehicle 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. .

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. 523319

Pretty easy to install. I originally ordered a more expensive version that was out of stock. This item is basically the same but a little cheaper. The one I originally ordered was to be connected to the truck bumper with self threading bolts. This one has little nuts and screws that are almost impossible to connect to the enclosed bumper. So I substituted my own self threading bolts. My other concern is the bracket could be a little stiffer. I'm not sure what the more expensive version is like, but this one could use a little more structure on the bracket. Time will tell how it will hold up. I may need some triangulated bracing on the sides to stiffen it up. Otherwise it appears to be what I wanted. I've yet to connect it to my trailers to see how it performs. 167500

Folks, if i can install this product, then ANYBODY can do it. Very very simple procedure and it fits perfect on my 2004 Chevy Silverado 1500 LS. No splicing wires or anything. I didnt use the mounting bracket that came with the part. I simply drilled 4 holes with a 38 drill bit and mounted the adapter to the O.E.M. original towing hitch adaptor bracket, using 4 screws and nuts that came with the mounting hardware with the new part. I didnt have the opportunity to buy mine Hopkins part 40955 from eTrailer because i already had the part. But if i ever need anything for towing or for my trailers that i didnt need to get right then and there, i would order online from eTrailer and wouldnt even think about looking elsewhere. The reason im posting this is to say THANK YOU to eTRAILER for all the informative videos and information on your website. KEEP UP THE GREAT WORK!!! From South Louisiana, I will certainly rate you 5*****s.

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 received the product within a couple of days of ordering. It was easy to install. All I had to do was just plug it into the existing factory wiring. The hardest part was mounting it to the vehicle in which required a drill and tap. 153977

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

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. 374585

Connected to a 2017 Jeep Grand Cherokee. Mounting holes did line up with Draw tite hitch. Connected to factory connector mounted on center of inside bumper fascia. Since I did not have factory tow, I had to have the dealer flash the ECU to activate functionality to the wiring. Cost to flash ECU $62. Had to shop,(most wanted $125). This was a whole lot easier and cheaper than other long way around the block harness options. Keep in mind that this will not operate the trailer break functions. Not a problem, I use a Tekonsha 90250 brake control mounted to the trailer and swap the hand held between vehicles. 510787

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

Spent a little time on phone with Preston discussing a wiring solution to accompany the trailer hitch desired. He recommended a product and confirmed that it should be a plug and play situation. Long story short, the hitch was bolted up and the wiring functional in 1 hr's time. I had to drill (2) holes to mount the wiring receptacle, but that was expected. Great service, fast delivery, and excellent prices. I'm very happy. Vehicle: 2005 Chev 1500, 4-dr, 6-1/2 ft bed. Note: Factory wiring harness trailer plug-in was located above the spare tire, towards the rear of the vehicle. 542780

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. 124445

The hitch went on quickly as well as the wiring harness. Saved myself over $60 dollars and about 45 minutes of time 263847



- 30955

by:


Good product overall. The wiring harness is almost too short and really needs to be wrapped with split tubing or somthing else to protect it from abrasion. The rubber plug covering the 4 flat harness feels like it could dry rot and fall off eventually and the mounting bracket is made from pretty thin metal. Overall the product could be beafed up a little bit and be made into a very good product. 118420

First one shipped had a short for the left turn signal, but it was returned no problem and a new one sent out. It fit perfectly into the stock electrical connection. I have used this for the several camping trips this year and am really pleased with the product. I also think that have the four bar will definitely be nice instead of having to have an adapter. 224596

Product was exactly what I needed. It connected right into my 2000 silverado and was easy to install. I could not find a connector for the standard gm wiring so I bought the whole setup and I didn't have to do very much work to get my truck towing again! It shipped quickly. Product is well made with good stress relief potting. Worth every penny! 273564

Unit worked well as advertised. Old connecter had to stay (was welded) so I mounted off center a foot away. Now it protrudes 2 inches. 371016

I use it infrequently. When I do use it, it works well. It would not mount as per instruction because of the factory offered trail hitch assy. Looks catiwhompus but does the job.

Rating is undecided but I couldn't leave field blank. I purchased same item last year and cover broke on one side soon after purchase with other side breaking off and losing cover a week ago. I checked to see if it was warranted (no)...so I purchased same item hoping other was defective... Time will tell... 242393

This product was easy to install and it seems to be made of good materials. I have been using it and it holds the trailer plug very well. One of the reasons I chose this one was because the one I had previously did not hold the trailer plug and it would come out. I plan on using it for a long time. 481799

Fit perfectly into the original harness. The bracket allows several mounting positions. The additional "Flat-4" plug is pretty handy, now I don't need an adapter taking up space in my glove box. Quality seems as good as or better than the original G.M. 469071

Do you have a question about this Custom Fit Vehicle Wiring?


  • 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...

  • Installing a 7-Way Trailer Connector on a 2000 Chevy Suburban
  • If your Suburban has a round connector to plug in a 7-Way, you could just use # 30955, which is a replacement 7 and 4-Way connector. On some models of the 2000 Chevy trucks and SUVs, there may not have been a tow package wiring plug located above the spare tire. Instead, there could be a bundle of wires. In the bundle of wires, look for the following colors: Yellow = left turn and brake light Dark Green = right turn and brake light Brown = tail lights White = ground Light Blue =...

  • The brake controller port on your 2005 GMC Yukon Denali will be located in the black junction box, which is under the dashboard and to the left of your steering column, right above the carpet. The plug in point will be the second port from the left, on the top row. I have included a link to instructions for a brake control wiring adapter # 3015-P that plugs in at this same point, if needed. If you do not already have a brake controller, I would recommend the Prodigy P2 # 90885,...

  • No 12V Power or Running Lights on 7-Way Trailer Connector on 2004 Chevrolet Avalanche
  • If the 7-way trailer connector on your 2004 Chevrolet Avalanche is part of a factory-installed tow package (if it is it should have a GM logo on it), then all wiring and fuses should be in place as part of the tow package. As you noted it is still possible that there may be fuses missing from the accessory fuse block in the engine compartment, or there may be blown fuses. It could also be that the wire lead for the 12V+ circuit is not connected at the fuse block. Please note that trailer...

  • Troubleshooting Trailer Lights Not Working and No Power at the 7-Way on a 2000 GMC Yukon
  • There could be a couple of causes leading to the lighting malfunction you are experiencing. The first things I would check are the ground connections on the vehicle side 7-Way, trailer side connector, and the grounds for the lights on the trailer. On most trailers, the lights ground through the mounting studs. Make sure that at each ground location, there is no dirt or corrosion. A bad ground connection is one of the leading causes of lighting malfunctions. You can also probe the wires...

If it is just bare wires with no plug, you will need to hard wire one in. The harness we have for this wiring situation is Pollak 7-Pole, RV-Style Trailer Connector Socket w/ Wiring Harness and Mounting Bracket, # PK11898.

  • Installing a Brake Controller on a 2007 Chevy Avalanche With or Without a Factory Tow Package
  • Yes, that is correct. Some model 2007 Chevy Avalanches have what is called a factory tow package that comes with a 7-Way connection at the rear of the vehicle, and/or wiring already ran under the dash for a brake controller. Some models do not have this factory tow package. You will be able to tell if you have a functioning 7-Way trailer plug at the rear of the vehicle. No matter which system you have, installation of a brake controller will be fairly simple on your vehicle. Even without...

  • Troubleshooting No Power At The Factory Trailer Plug

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 # 3808....

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.

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...
