Speaker 1: Today on our 2018 Jeep Grand Cherokee, we're going to be installing Hopkins 7-way and 4-way trailer connectors, part number 30955. This 7-pole connector's going to plug directly into your factory wiring harness, providing you with all the necessary trailer signals from both a 4-pole flat connector and a 7-pole connector. Both connectors are going to provide you with the necessary lighting signals, such as your left turn, right turn, brake lamp and stop lamp signals. Your 7-pole's going to have some additional wiring in it for a brake controller signal, auxiliary power and backup lamps. The 7-pole connector has a spring-loaded door with a seal located on the inside to keep out moisture and corrosion.The 4-pole connector has a dust cap that can be removed and reinstalled to help keep out dirt, debris and moisture. This is ideal if you have multiple different trailers.
If you have a small trailer for hauling things around that just needs lighting, you've got your 4-pole. Let's say you've got a boat trailer to haul a big boat that uses a brake controller. You've got your 7-pole here for that. Whatever situation, you're ready to go.We'll begin our installation by installing our 7-pole bracket onto our hitch. If your hitch doesn't have a built-in bracket, you may need to purchase a short or long bracket.
You can find one of those here at etrailer.com. Start by preparing your screw. You'll place on a lock washer, followed by a flat washer, then we'll slide those down through the openings in our bracket. We'll then slide our 7-pole bracket up onto it, and thread the nut on the other side. Then tighten those down with a 10 millimeter socket and Phillips head screwdriver.
Next spot your 7-pole connector by sliding the harness through the small slit at the bottom of the bracket and sliding the longer flathead screws through each of the openings in the face.Then on the backside, thread on your locking nuts. And repeat that for the three remaining screws. Then tighten them down with a flat-bladed screwdriver and a 10 millimeter wrench. Now underneath the vehicle at the rear bumper on the driver's side, you'll find your factory tow connector. Inside there's a dummy plug we'll have to remove.
So you'll push down on the release tab here, and pull out on the dummy plug. Then you can just set this aside. We'll then add some dielectric grease to the terminals inside of our 7-pole. This'll help keep out any moisture and corrosion. Then we can just plug it in. Make sure the connector's fully seated, you should hear it and feel it click into place. Now you want to plug it into your trailer or use a tester, such as the one that we use here at etrailer, part number I26 to make sure everything's working properly. If you don't have any signals out of your tester or your trailer, you may need to go to the dealer and get the computer flash to make it operative.That completes our installation of Hopkins 7-way and 4-way trailer connectors on our 2018 Jeep Grand Cherokee.

Just installed, took 15 minutes. 5 minutes getting tools & two self tap screws out of shop. Very good pro 576747
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 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
Fast Ship! Worked perfect, Thank you 528930
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
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
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
Worked fine for the few months I had the truck
Identical wiring, configuration, and mounting to original part. Therefore installation was easy. 589835
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
I am completely satisfied. The package arrived quickly and I was able to install on my truck the same day with help from the installation videos. I will definitely purchase from etrailer.com in the future. I have saved money by spending with etrailer.com and doing the upgrades myself. 576830
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
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
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
This part is also really great and fits perfect thank you !!!! 593843
Finally updated my truck to a better working area for working with trailers without getting down on your knee when hooking up. When I got done drilling the big hole in the bumper, it went quite smoothly. 707666
just a little pricey 706016

Bracket is too weak. It bends when trying to plug up. I got to figure out how to make stronger. 642850
Just what the doctor ordered. It is as if the purchased trailer connector was tailor made for my vehicle. Perfect fit and installation was a breeze. This connector is a replacement of the factory one that was attached to the truck. Very pleased in the product as well as 'etrailer.com'. 636994
Easy plug and play perfect for what I was looking for. 628858
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. 628856

Easy to install, works well except that two lights stopped working after about 10 days... otherwise product is good. 614692

Cathy T. was very helpful in completing my order. I ordered 30 but etrailer did not have enough in stock to complete my order. Cathy was very helpful in completing my order and getting them delivered to me on time to complete our production run. 557117

Very nice! 551544
I ordered this for a friend oversees and he is happy with it. 550574
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
Still works great - no issues at all.
Excellent 538318
Good product but had to modify mounting a little to make it fit. 526430
