Today we are going to install a 4-pole and 7-pole connector by Hoppy, part number 30955, on a 2006 GMC Sierra. This wiring connector that we are installing goes right into the factory connector. So I would start with lowering the spare tire for good visibility. You are going to want to take the existing wiring down so you can use this excess slack to run it to the bumper so you can mount the connector. Once you get the wiring harness taken down and the cap pulled off, then you are going to need to mount your mounting bracket to the bumper. Once you find a good location, mount the bracket with the self-tapping screws.
Now that we have the bracket installed, we are going to install the 4-pole and 7-pole connector to the factory wiring harness. Then we are going to connect them first and then we will mount our hardware. Now, once you have everything connected, then go ahead and finish mounting the connector to the bracket. Once you have everything buttoned up here, we are going to zip-tie the wires to the existing wires so they are out of the way. And that concludes our install of the 4-pole and 7-pole connector by Hoppy, part number 30955, on a 2006 GMC Sierra.

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.
Perfect fit just plug and play good quality hitch.
Perfect fit and function as usual from etrailer.
Great fit works good has 7way rv plug and the regular flat 4 plug no need for adapters to lose or have stolen.
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.
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.
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.
Works great!!! Thanks....
Product exactly what I was looking for. Fit factory harness perfectly. Strong and rigid, appropriate mounting hardware. Perfect
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.
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..
Easy install. Black plastic cover broke of very quickly.
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.
Perfect fit. Could not ask for anything else.
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!
worked great thanks
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.
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.
Jaime B was very knowledgeable, helpful and nice.
Hitch and wire harness fit great.
Delivery was 2 days earlier than expected.
Great job etrailer.
Quick shipping. And best part they sent me the correct hitch and plug in. No complaints here!
The male prongs on the plug on the wire end were too short and did not engage.
The lights would not work. I bought another brand plug that the prongs were longer on and it worked fine.
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.

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.
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.
Bought this 7 way connector to replace my current 5 pin. It fit into the factory wiring and came with a bracket and screws. Fast shipping and 10 minutes to install. Thanks Etrailer
