Mounted this on a 1998 Jeep Cherokee XJ with factory towing to replace the 7 pole round socket, the connection into the factory harness was plug and play, perfect fit, bracket easily mounted to my Heavy off road bumper, looks like it belonged there all along.

Really fast shipping. Product just as described. The bracket is strong and sturdy.

Found out I didn't need the wiring harness. The Jeep just plugged right into the back of the 7 way. was done in 7 minutes. Not knowing I didn't need the wiring harness would have save me $45.

If you do not need the wiring on your 2017 Jeep Grand Cherokee I recommend part # HM40975.

Thanks to the excellent customer service Rep (Nicole T ). I was able to install my trailer hitch and harness with ease. So easy my 7 & 8 yr olds did it. looks great on my 2015 Grand Cherokee limited. we can't wait to mount the bike rack and goooooo! Thank you too much Nicole T.

15 minute install. High quality craftsmanship. Would highly recommend!!! Incredibly clean install on a brand new vehicle



by:

Of course, price matters - and everything is too expensive right now, but what matters more is quality. I appreciate being able to contact someone (you), and get just what I’m looking for. The quality seems completely top notch, and I’m anxious to get this installed and start using it.



by:

The kit was easy to replace. I had water intrusion and the connections were corroded. I am now getting the same fault code/warning on my truck a year later. Not sure if this replacement part has water / failed - need to remove once the weather warms up.

Hi Terry, Thanks for your feedback! When using these connectors, I would recommend using dielectric grease to help keep contaminates out of the connection points. Using Loctite Bulb, Lamp, and Electrical Connection Dielectric Grease, part LT37534 , will help prevent the corrosion of the connectors.



by:
Jeep Grand Cherokee

After one year the product is still performing well. The cable provided made it easy to attach it to my stock wiring harness on the Grand Cherokee.



by:

This company have been nothing but understanding and professional. I ordered my parts for my new RV and they came through without a hitch. I liked that I could track the package along the way. Keep up the good work y’all



by:
2018 Jeep Grand Cherokee

My 2018 Grand Cherokee didn't need the wire harness, so it cost me an extra 20 some dollars per part I didn't need, so jeep owners look under and see if you have a round plug in the back with a end cap on. No one tells you what to look for.

This part is only sold with the harness and the bracket included. This plug will not fit into the factory sockets or mounts for 7-ways. The closes thing we have that might be able to fit your factory opening is part 30955.

  • How to Install 7-Way Connector on 2005 Dodge Ram 1500 with Factory 4-Way
    I do have a solution for you, but the # HM40975-11933 will not work since your 2005 Dodge Ram Pickup did not come with a factory 7-Way trailer connector. If what you're looking to do is upgrade your factory 4-Pole connector to a fully functioning 7-way, then what you need is the 7-Way RV Upgrade Kit for Trailer Brake Controller Installation # ETBC7. This will allow you to run your brake output, reverse light and 12V power wires, which aren't pre-wired from the factory on your truck.

  • Will the Draw-Tite Hitch 41948 Fit a 2019 Ram 1500 Classic Warlock Special Edition
    The Draw-Tite Ultra Frame Trailer Hitch Receiver part # 41948 is a fit for a 2019 Ram 1500 Classic Warlock Special Edition so long as you don't have a factory trailer hitch. The Draw-Tite hitch offers a complete bolt-on installation with heavy duty towing capacity of 12,000 lbs. If you don't already have a trailer wiring harness, the 7- and 4-Pole Trailer Connector Socket part # HM40975-11933 fits into the factory bumper cutout.

  • Would Pollak 7/4-Pole Trailer Connector HM40975-11933 Connect To Mopar Harness on 2015 Wrangler
    Yes, the square connector of the part # HM40975-11933 would attach directly to the square connector of the OEM Mopar wiring harness you have installed on your 2015 Jeep Wrangler Unlimited.

  • Fit of Draw-Tite Class III 76050 Trailer Hitch On Extended Model 2020 Ram ProMaster 3500
    According to Draw-Tite, their # 76050 Class III hitch is a fit for the 2020 Ram ProMaster 3500 Extended model. For a trailer wiring harness on vehicles without the tow package, use # 22112 or # HM40975-11933 for tow package equipped vehicles. For a ball mount, use # C45230 along with the # PC3 hitch pin. For a 1-7/8 inch trailer ball, use # 19260 or # 63845 for a 2 inch ball. I've linked to some installation videos that you might find helpful.

  • What Parts Will Be Needed to Install a Brake Controller and 7-Way Connector to a 2015 Jeep Wrangler
    You will need to install a 7-Way connector when installing a brake controller to your 2015 Jeep Wrangler Unlimited. For that you will want the Brake Controller Install Kit and 7-Way Adapter part # ETBC7. I attached installation instructions and an install video for this product as well. For a brake controller I recommend the Prodigy P2 Brake Controller part # 90885. This is our best selling brake controller because of how well it works and how easy it is to setup.

  • Parts Needed to Install 7-Way Trailer Wiring Harness in 2005 Jeep Wrangler
    The reason the wiring harness of the Hopkins 7-Way Kit part # HM40975-11933 seems short is because it's for connecting to existing trailer wiring on your 2005 Jeep Wrangler. If your Wrangler did not have a 7-way present at the rear of it then this would not work. You will need to start with a 4-way (if you do not have one). For that you would want the # 118409. 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....

  • Recommended Trailer Connector And Wiring Harness For 2014 Jeep Wrangler Unlimited With Tow Package
    For your 2014 Jeep Wrangler Unlimited with factory tow package, I recommend the Pollak 7- and 4-Pole Trailer Connector Socket w/ Mounting Bracket, Chrysler/Dodge OEM Plug Adapter # HM40975-11933. This kit gives you the wiring adapter you were asking for as well as the trailer connection with both 7-way and 4-way connections you were asking for. This is a confirmed fit for your vehicle with factory tow package.

  • Recommended Trailer Hitch and 7-Way Wiring for 2021 Chrysler Pacifica Limited
    It sounds like your ultimate goal is to have a trailer hitch receiver and a 7-way on your 2021 Chrysler Pacifica. I will start by addressing the # HM40975-11933. This adapter is not confirmed to fit your vehicle so it is not something you would want to use even though the bracket would fit the hitch mounting point. The Draw-Tite Max-Frame Trailer Hitch Receiver # 76046 is a great choice for your Pacifica. You mentioned it was a round hitch, but that won't make a difference aside from the...

  • Installation of Brake Controller on 2013 Jeep Wrangler Unlimited With Factory Tow Package
    Since you have the factory tow package on your 2013 Jeep Wrangler unlimited, the installation of the # HM40975-11933 is all that is necessary for a working 7-way. However, you will need some additional wiring to get your brake controller installed. You will need to locate the coiled up light green or blue brake output wire near the emergency brake pedal. You will also need the # 5506 to add circuit breakers and run wire from the battery to provide power as well as a ground connection....

  • Installing 7-Way Trailer Connector on 2010 Ford Escape with Existing 4-Pole
    To convert your existing 4-pole to a 7-way trailer connector, I would recommend using an adapter, like part # 37185. The adapter would plug into your existing 4-pole, and once the white wire is grounded, and the trailer is plugged in, your trailer lighting functions will be active. The blue, black and purple wires carry the brake output, 12-volt accessory power and reverse light circuit, respectively. If either of the three circuits is not needed, one or all three wires can be bundled up...

This will connect your factory plug to give you the trailer connector. To have a fully functional system, I recommend adding the Tekonsha Prodigy P3 # 90195 brake controller using wiring harness # 3024-P. This is a great system that will give you an LCD screen, 3 levels of boost, and storable settings as well as diagnostics...

  • Fit of Pollak # HM40975-11933 7-Way/4-Pole Connector on 2006 Jeep Liberty Factory 7-Way
    The Pollak 7-way/4-pole Connector you referenced, part # HM40975-11933 will indeed replace the existing 7-way on your 2006 Jeep Liberty. The only possible knock on this connector is that both the 7-way and the 4-pole can't be used simultaneously, as both the protective covers won't open at the same time. If that's not a problem for you, this connector would work just fine. The Tow Ready # 20135 would also be a fit, and both connectors could be used at the same time. I've linked you to...

  • 7-Way Recommendation for 2017 Jeep Wrangler Unlimited
    Since you have the factory 4-way and the tow package to swap out to a 7-way would only require the part # HM40975-11933. This will install in place of the 4-way square connector and give you both a 4 and 7-way.

  • Parts Needed to Install 7-Way on 2017 Jeep Wrangler
    The tow package for your 2017 Jeep Wrangler would have included a 7-way at the rear of it and not a 4-way which is why the # HM40975-11933 is not able to plug into your vehicle wiring. So while we have a solution for you it won't be with the part # HM40975-11933. 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....

  • Adding a 7-Way Trailer Connector a 2012 Jeep Wrangler for a Brake Controller
    Since your 2012 Jeep Wrangler has the tow package your 4-way trailer connector should be able to be unplugged underneath the bumper. You can replace it with a 4- and 7-way connector, part # HM40975-11933. If your Jeep doesn't have a plug in for that harness then instead you can convert your existing 4-way to a 7-way using our # ETBC7 kit. It plugs into the 4-way and then you run the other wires for the additional functions. The black wire goes to the Jeep's battery, the blue wire will...

  • 7-Way Trailer Connector and Brake Controller Installation in 2018 Dodge Durango
    The 4 pole trailer connector on your 2018 Dodge Durango is likely aftermarket, but there's a chance the vehicle is prewired for a brake controller and a 7-way. Check under the dash to see if the vehicle is equipped with the connector for installing a brake controller. The connector, if it's present, would be located to the left of the steering column, near the top of the e-brake pedal. It'll usually be taped to a different wiring harness. If the connector is there, look under the vehicle...

First is the T-One Vehicle Wiring Harness # 118381 which is only going to give you a 4-way flat connector.

    The OEM plug that would allow you to use the # HM40975-11933 should be found at the rear of your 2022 Ram 5500. Everything indicates that your truck has the rectangular factory plug that would allow you to use this wiring harness. Typically this would be found behind a cover for the 7-way but I don't have an exact location for a 5500 cab and chassis. If you still can't find it you could check for a brake controller port. This would have the brake output wire that runs back to the 7-way...

    Usually when there is a question on the function of a wire the solution is to test that wire. But you indicated that you have tested the wires and still cannot figure out the functions. But you didn't say why that is. Were you getting conflicting readings from the meter? A meter might be a little too sensitive for this test. Really all that is needed is a circuit tester such as # PTW2993. Two of the wires will show power when the brake pedal is pressed. And one of those wires will also...
