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.



by:

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



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.

2017 Jeep Grand Cherokee

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.



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.

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

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.

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

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:
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.

Patrick B.

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.

  • Easy to Install Trailer Brake Controller for 2008 Jeep Wrangler Unlimited with 4-Pole Wiring
    Yes, we can help you with the items needed to upgrade the 4-pole wiring on the 2008 Wrangler Unlimited to a 7-way and to install a trailer brake controller. The Jeep does not have an under-dash port to connect a controller but we do have an option that will be very easy to install. For the easiest possible installation I recommend the Curt Echo # C51180 and 7-way upgrade/install kit # ETBC7L. If your Dad has a compatible smartphone then these two items are all that is needed to add the...

  • 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...

  • Where is the Running Light Fuse for Trailer on 2013 Ram 1500
    From what I could find, the fuse is in the underhood fuse box next to the battery. Check the yellow 20 Amp fuse in location F29. That should be for the trailer running/parking lights. If I were you, then I would also check the Pink 30 Amp fuse in location F30. That is for the trailer connector itself, so it wouldn't hurt to make sure it is okay as well. There is also a 15 Amp Blue fuse in location F79 for your truck's clearance lights. This fuse shouldn't have any bearing on the trailer's...

  • Trailer Wiring Recommendation For 2017 Jeep Grand Cherokee
    The Pollak 7-Way part # HM40975-11933 is a fit for your 2017 Jeep Grand Cherokee and would plug into a square connector at the rear of the vehicle. Most likely it's the connector you found already based on what you described. You might test the pins of the connector you found with a circuit tester like part # PTW2993. If they are active when vehicle taillight signals are on then this will work. If instead you do not have the tow package wiring complete the T-one kit part # 118727 would...

  • How to Clean the Contact Points of a Trailer Connector
    You have a few options for cleaning the pins of a trailer connector. You could use a wire brush, some fine grit sandpaper, or even Coca-Cola and an old toothbrush. Coke does a great job cleaning corrosion believe it or not. You'll want to rinse the soda off after though since sugary drinks leave a sticky residue.

  • 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.

  • Parts Needed To Haul 800 lb Motorcycle & Trailer With A 2014 Jeep Cherokee
    I would recommend getting a Class III 2 inch Hitch Receiver # C13172. This Curt hitch will have plenty of strength to haul your 800lb motorcycle and trailer. It will fit a 2014 Jeep Cherokee Trailhawk or Non-Trailhawk version. If you have the factory tow package all you need is this trailer connector # HM40975-11933 but if you to not, you will need this vehicle wiring harness # 118605. You'll need a ball mount to haul your trailer. I would say a 4 inch rise ball mount # D-28 would counteract...

  • Replacement Mounting Bracket For A 7 And 4-Pole Trailer Connector Socket

This is a universal mount option that will allow you to place the bracket in any location you see fit. I have attached a product review for your viewing.

The class IV receiver is capable of supporting up to 1,125lbs of tongue weight and towing 7,500lbs. With a weight distribution hitch the capacities are 900lbs of tongue weight and 7,500lbs towing.

  • Troubleshooting 7-way Trailer Connector on 2004 Jeep Grand Cherokee
    The existing turn signal/brake lamp circuits are already converted, so you shouldn't need an additional converter. I'd recommend checking the fuse box under the dash and in the engine compartment, and locating the right and left trailer turn signal/brake lamp fuses, to make sure they're installed and not blown. Replace as needed. I'd also closely examine the pins on the 7-way for corrosion. If you see any green or white corrosion on the pins, the corrosion could have spread inside the...

  • 7-Way Trailer Connector Installation on 2011 Jeep Wrangler
    If you're needing a 7-way trailer connector for your 2011 Wrangler (which is what it sounds like), you'll need to start by installing a 4-pole connector using part # 118416. How you'll proceed from here depends on if your trailer has electric brakes or not. If it does not, you'll also need the 4-pole to 7-way adapter, part # 37185 which plugs into the 4-pole provided by the # 118416. Once plugged in, the adapter has 4 additional wires. The white wire is grounded to the vehicle frame, and...

  • Will Hopkins HM50002 Smart Hitch Backup Camera Plug and Play Install on 2007 Dodge Ram
    The answer to your question will depend on what kind of factory connector your 7-way plugs into. If the connector that plugs directly into the rear of your 7-way trailer connector is round, then the Hopkins # HM50002 Smart Hitch Backup Camera system will be a plug and play installation. If the connector plugs into a rectangular connector, you can simply replace the existing 7-way with part # HM40975-11933 which will plug into the rectangular connector while providing a round connector...

  • How To Have A 7-Way And 4-Way Connector On A 2008 Dodge Ram Without A Factory 7-Way Plug
    The Pollak Custom Fit Vehicle Wiring, # HM40975-11933, is a replacement connector for the Dodge Ram trucks with the factory plug under the truck on the drivers side. If your 2008 Dodge Ram 1500 does not have the factory trailer wiring harness available, then you will need to use the Draw-Tite Wiring Harness, # 119178KIT, and the 7 and 4 Way Installation Kit, # ETBC7. That will give you the 7 and 4 Way connector at the rear of the truck. The part # 119178KIT wiring harness installs behind...

  • Recommended Trailer Connector And Wiring Harness For 2014 Jeep Wrangler Unlimited With Tow Package

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.

  • Trailer Wiring Harness Recommendation to Replace OEM Wiring on a 2004 Dodge Ram 2500
    We have a variety of replacement wiring connectors for your 2004 Dodge Ram 2500, like the Pollak # HM40975-11933 for a full replacement, the T-One # 118381 that tees in with a 4-Way, or the Curt # C55504 that plugs in behind the tail lights for power and signals. From what you're describing it sounds like you're wanting the Curt harness that essentially works outside of the OEM trailer wiring harness. Please note that while this will allow you to tow a trailer with a 4-Way quite easily,...

  • Recommended Brake Controller for a 2015 Ram 1500 4x4
    The brake controller that I recommend for you to use with your 2015 Ram 1500 is the Tekonsha Prodigy P3 # 90195. This is a proportional brake controller which means it will apply the brakes on your trailer at the same time and with the same intensity that you apply the brakes to your Ram. The P3 is also very easy to setup and features an easy-to-read LCD screen which makes adjusting the different settings a little easier to navigate. This brake controller can be plugged into the connector...

    You will need to start with a 4-way (if you do not have one). For that you would want the # C55124. 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. This gives you the ability to have a 4-way too. If you do have trailer brakes you would need the # ETBC7 instead of the # 37185 and a brake controller. This kit comes with everything needed to wire up the 7-way and install a brake controller.

You just find the connection points beneath the rear bumper. For a 7-way connector you will need part # ETBC7. Usually, a 7-way connector is used because the trailer has brakes. If that is the case then you may be interested in a brake controller like part # 90885. This is our most popular brake controller because it is easy to install and operate. I...

  • Adapter to Go From 4-Way Vehicle Connector to European 13 Pin
    Unfortunately we do not have an adapter to go from a European 13-way trailer connector to a U.S. style 4-way vehicle connector. European trailers typically have separate brake light and turn signal circuits, but U.S. trailers use a combined wiring system that use one wire for the turn signals and brake lights. You could make an adapter using a universal 4-way flat tail light converter like part # 119130, but you would need to find a European trailer side 13-way connector that can be rewired....

Because you have the factory 4-flat connector, you will have the wiring needed for your brake controller.
