The trailer hitch plus 7-4 Pole trailer connector all fit perfect on my 2018 Grand Cherokee. Installed it myself with the help of a couple of jack stands to support the hitch while I bolted it in. Saved a bundle over having the dealership install the Jeep brand. The hitch is barely noticeable. The only issue with a jeep is they do not activate the connector plug so I had to have the dealer activate it after I installed it.

It came with it's own bracket, which is a plus. It was compatible with etrailer.com's part number C56357, which is also a plus. The self tapping screws being the only hardware coming with the item was a disappointment. I just installed etrailer.com's part number 76301 hitch receiver which has a mounting plate for brackets like this. The self tapping screws, which might have been effective, wouldn't have looked "professional." After finding some hardware which worked, it went on smoothly and fits well with the rest of the assembly.

2015 Audi Q7

Scratched my head for a while, trying to find a quality way to connect this vehicle end 4/7 wire socket to my trailer ready (almost) 2015 Audi Q7. Finally decided that it really didn’t need to be bolted, but could be hose clamped to the existing heavy duty Audi bracket. Mounted it sideways with a 1” diameter and a 3” diameter hose clamp. Be sure to use a 3” clamp with lots of serrations that all it to tighten it down a lot. You’ll need to drill out the small hole of the supplied bracket to allow a clamp to fit through it. The other hole is a slot, and works unaltered. Small clamp on bottom, large clamp on top. You’ll also need to relieve a small spot on the trim piece to make room for the 4-wire door to o-en freely. This is marked as red on one of the pictures. Looks good and should work good!

I just received my package from Etrailer.com and it was nice to open the box and have the right part/part I ordered arrive. Opened up the box staged my parts and started the install. It was very easy with the instructions that were sent and the video on their site that anyone can do this install with no issues. Hitch was on in no less than 15 mins from opening of the box to final torquing of the bolts. The customer service at this company is top notch. I have never had anyone from a company email me before after ordering from them like I did with this company and in business today you are seeing less and less of this type of customer care and service. AWESOME job Guys and Gals I will buy all my accessories from here.

I really like this trailer plug since it converts a standard 7 Wire plug into both a 7 wire and 4 wire. It plugs directly into the factory wiring harness. it comes with everything you need to mount it (bracket and self tapping screws). It was an easy install. My 05 Chevy Tahoe had the factory 7 wire outlet bracket, I left that in place and mounted this bracket just to the left of it. I highly recommend this product.

2003 Ford F-250 and F-350 Super Duty

I really like this product. I like that the 7 blade and the 4pin plugs are internally wired. It is truley a 'plug-n-play' unit and even has corrosion preventitive in the pins. The reason I did not give this kit an 'excellent' rating is the mount bracket is too short. This required that a use a 1 inch spacer and longer bolt to attach the mount so the trailer plug could be inserted.

2010 Ford F-150

This is a plug-in replacement for my 2010 Ford F-150 with factory installed trailer package. I had this exact same connector but someone unclipped it and stole it. Ford Parts wanted over $100 for a replacemnt (they included the entire rear bumper harness that I did not need). I had the cutout on the hitch that exactly matched this bracket and the blue socket that you see in the optional pigtail available for this product (see attached photo). I snapped this dual connector into my existing cutout - fit perfectly. Did not need to use the included bracket. So if your factory connector is damaged or stolen, use this as a snap-in replacement. The only difference is it says "Pollack" instead of "Ford". I called Hopkins before I bought and they said they supplied a lot of the OE parts Ford uses.

Good product, fits perfectly in factory location. I've only pulled a trailer a couple times since purchasing this kit & both times I've had to steady the base when unplugging connection, to keep the assembly from trying to come loose from bracket, hence the 4 Star rating. Overall pleased.

Excellent quality. Only took 5 minutes to install. Outstanding customer service!! Ordered online on Friday and received via USPS on Monday, with emails letting me know the order was received, the item was shipped, and one that stated that the company had received information that the item had been delivered. And each one was signed by an individual. If only all companies operated this way.

nice looking product, haven't plugged into it yet to know of the electrical part, caution about the install, make sure you have about 5" clear directly behind the install location of your bracket to allow room for the connector and to attach your vehicle plug, see photo, I had wanted to mount this on the bottom of my bumper, but not enough clearance

A no-drill mounting bracket like # C57202

is a great way to give clearance needed to mount the wiring connector higher up on the hitch.

Easy peasey lemon squeezy! Mounted up easy on the Draw-Tite hitch. Slathered on some dielectric grease, plugged in the factory harness and we’re good to go. Looks factory VS just having the loose 4 pin flat connector dangling out in space. Nice spring loaded doors with gaskets to keep connectors clean. Having the 7 and the 4 pin means it’s ready for anything. It’s a no brainer.

  • Trailer Wiring Kit for 2020 Dodge Durango
    To determine if you have the Factory tow package on your 2020 Dodge Durango I would look under the vehicle between the spare tire and rear bumper for the factory connector. If you see the round connector about 1-1/2" in diameter with a blank plug than you do have the wiring. If you don't have the vehicle or capability to look underneath it you can always contact a dealership with your VIN number and they can tell you every option that Durango came with.

You can use the T-One Vehicle Wiring Harness # 118287, which is confirmed to fit your Traverse, and plugs directly into your factory harness. You can then use the Hopkins # HM40975 in place of the 7-way socket that comes with the harness. The # HM40975 also comes with a mounting bracket to easily attach it.
