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.

2015 Jeep Grand Cherokee

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.



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



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:
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:
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.

  • Parts Needed To Add 7-way Connector To 2008 Dodge Ram 1500 Towing Small Travel Trailer
    Since your 2008 Dodge Ram 1500 does not have the factory 7-way connector, but has a 4-way connector you can easily add a 7-way connector using the # ETBC7. This will plug in to your existing 4-way connector and just require a few more connections. You will ground the white wire to the frame of the truck, run the blue wire to where you are planning on adding a trailer brake controller (If the trailer has trailer brakes, if it does not I would run the wire under the dash so it is there should...

  • Troubleshooting Trailer Brakes that Lock Up with no Electric Brake Controller Installed
    You have a short somewhere on the brake output wire going back to the 7-way trailer connector on your 2013 Dodge Durango. I would start at the 7-way and inspect the connector and the brake wire. The brake connects to the pin in a 5 O'clock position when looking into the connector. If you find the problem on the trailer connector harness before it plugs into the truck's wiring you can either fix the wire or replace the harness with # HM40975-11933. If it's deeper into the truck or you...

  • 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.

  • Trailer Lights Stay on Once Vehicle Ignition is Shut Off
    I suspect your problem is caused by a damaged or corroded trailer connector. Take a look at your trailer connectors, both the socket on your truck as well as the plug on the trailer. Look for green or white corrosion on the pins or sockets of the connectors. If corrosion is visible, there is a strong possibility that the corrosion has spread to the interior of the connector. The terminals that each individual circuit connects to are very close together, if corrosion builds up on the terminals,...

  • Replacement 4 and 7-Way Trailer Connector for a 2012 Ford F-150
    The wiring harness that is included with 7 and 4-Way connector # HM40975-11933 is # PK11933 which is designed to fit certain Dodge/Chrysler vehicles. For your 2012 Ford F-150 you would need # HM40975 as a replacement and if you also need the harness that connects to the back you would need # PK11998 which is a hardwire harness.

  • 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,...

  • Parts Needed to Install 4-Way and 7-Way Connectors on a 2016 Jeep Wrangler Unlimited
    If you don't already have electrical connectors on your 2016 Jeep Wrangler Unlimited then you will need to start off by installing a 4-Way connector like the T-One # 118416. This plugs in behind your tail lights and will give you the basic lighting functions for your trailer. One the T-One is installed you need to install the Universal Wiring Kit # ETBC7. This comes with all of the wiring and connectors you need to have a fully-functioning 7-way (and 4-Way) at the rear of your Jeep. If...

  • Converting 4-Way Trailer Connector to a 4- and 7-Way Connector on a 2017 Jeep Wrangler Unlimited
    Take a look at how the factory 4-way of your 2017 Jeep Wrangler Unlimited is installed. Follow the harness to see where it plugs in. If it has a rectangular connector like the # HM40975-11933 plugs into then this will work for you. You also will need to add wiring using our # 5506 kit in order to install a brake controller. If your Jeep's 4-way doesn't plug in using that type of connector, or if you just want to run everything new instead of having to find the correct wires in the Jeep...

  • 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...

  • Brake Controller and Wiring Harness for a 2016 Jeep Grand Cherokee with Factory 7-Way Connector
    Of the 3 vehicles you are looking at it will be easiest to add a brake controller to the 2016 Jeep Grand Cherokee with a factory tow package that includes the factory 7-Way trailer connector. The others, Volvo XC90 or Honda Pilot, would require at least a partial hardwire of the brake controller and routing wires through the firewall and splicing into the brake switch. With the Jeep Grand Cherokee with factory 7-Way all you will need is the brake controller and wiring harness. I recommend...

  • 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.

  • Do You Have the Bracket Separate From the HM40975 Connector
    I am sorry but at this time we do not sell the bracket separately for the HM40975-11933. We do have the Pollak 7- and 4-Pole Trailer Connector Socket w/ Mounting Bracket, part number HM40975, available without the plug adapter wiring.

First you would need to start with a 4-way like the part # 118416 which is a confirmed. 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.

  • Location of Fuse that Controls Trailer Lighting on 2013 Ram Diesel
    If the trailer lamps aren't working, you'll first want to determine if the cause is with the vehicle or with the trailer. Use a circuit tester like # 40376 to check the pins on the trailer connector while somebody activates each lighting function. If you get signal on the pins, then the problem lies with the trailer, and not the vehicle. With no signal at the pins, then unplug the wiring harness from the rear of the 7-way trailer connector, and test the pins on the socket. If you get signal...

  • Adding 4-Way Trailer Connector to 2016 Jeep Cherokee Trailhawk with OEM 7- and 4-Way Connector
    The Hopkins Plug-In Simple Vehicle Wiring Connector # HM11142464 referenced in your question will plug into ports behind the driver and passenger side tail lights on your 2016 Jeep Cherokee Trailhawk to provide you with an additional 4-Way connector. Because it will be wired to different circuits than your existing OEM 7- and 4-Way connector both connectors can be used at the same time.

  • 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...

As for a brake controller itself, I strongly recommend the Prodigy P3 # 90195; it is the most popular model we carry due to its effectiveness and ease of use. It will activate your trailer's brakes immediately in proportion to your Jeep's brakes and offers three different boost levels...
