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!

Good installation approach for q7’s. Keeps water from collecting in wiring junctions.

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.

2005 Chevrolet Tahoe
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
Curt No-Drill Bracket for 6-Way or 7-Way Round Trailer Connector Mounting Bracket - Long
$14.83 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.

view full answer... - Parts Needed to Install a 7-Way on a 2017 Ford Transit T250Your 2017 Ford Transit T250 will have a round connector at the rear of it that the part # HM40975 would connect directly to since your vehicle has the tow package. If it didn't have the tow package you'd need to start with a 4-way like part # 118643. Now if your trailer does not have brakes all you would need is the part # 37185 as an adapter to convert the 4-way to a 7-way. If you do have trailer brakes you would need the # ETBC7 instead of the # 37185 and a brake controller....
view full answer... - Replacement Trailer Connector For 2013 Ford F-250 With OEM 7-Way I recommend the Pollak 7- and 4-Pole Trailer Connector Socket w/ Mounting Bracket, part # HM40975 for your 2013 Ford F-250. I spoke with my contact at Hopkins and they said this the direct replacement for your F-250 if you have the oblong connector. It will snap right into place. This will let you tow trailers with either a 4-way or 7-way connector. The covers on the socket will not open far enough to allow you to be able to use both plugs at the same time
view full answer... - Parts Needed To Install 7-way Trailer Connector on 2000 Toyota TundraWe do have a solution that would allow you to install a 7-way trailer connector on your Tundra, but the # HM43385 7-way connector wasn't a fit for the Tundra until the 2003 model year. To install the 7-way, you'll need functional 4-pole connector. If you don't have one, you can install one using part # 118367. How you proceed from here will depend on whether or not your trailer has brakes. If it does not, you can simply use an adapter like part # 37185. Plug the adapter into the 4-pole...
view full answer... - Installing a 7- and 4-Way Trailer Connector on a 2017 Ford Escape with Factory 4-Way ConnectorTrailer connector # HM40975 is meant as a replacement for a factory 7-Way trailer connector so to install it on your 2017 Ford Escape it is going to take some additional parts. If you do not already have that part then I recommend using # ETBC7 instead because it is easier and minimizes the additional parts you will need. For either part you can mount the bracket for it in a place that is convenient for you. Typically they are found on the driver's side of the vehicle. The factory mounting...
