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

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.

  • 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....

  • 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.

  • 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....

  • Replacing Broken 7-Way Trailer Connector on 2002 Ford F150
    Going with the # PK11998 would be your best bet. The 4-foot pigtail does include the grey locking tab you speak of, as shown in the photo I edited for you. I will also provide the color code for the pigtail wiring, as it might not necessarily wire up color-for-color to your F150. To determine function, you might need a circuit tester like part # PTW2993, if you do not already have one.

  • Adding a 7-Way Trailer Connector and Electric Brake Controller to 2011 Jeep Wrangler Unlimited
    Since your 2011 Jeep Wrangler Unlimited has the factory tow package there should be a square plug for the Pollak # HM40975-11933 to plug into. This will work well to supply a 7-way trailer connector. If you need to run wiring to install a brake controller use # 5506. If you don't have the square connector you'll first need to add a 4-way using # 118416 and then convert that 4-way to a 7-way using our # ETBC7 kit. This includes the 7-way and everything you need for an electric brake...

  • Troubleshooting No Trailer Brake Lights When Connected to a 2015 Ram 2500
    You are definitely on the right track, but when I looked up the online owner's manual for your 2015 Ram 2500 the F11 cartridge fuse is actually for the trailer brakes themselves which is a different circuit than the brake lights. For the brake lights you need to look at fuses F53 and F81 which carry the left turn/stop and right turn/stop light circuits respectively. If those fuses look good as well then you need to test the 7-Way connector on your Ram or plug your trailer up to a different...

  • Will Pollak 7- and 4-Pole Trailer Connector Socket Fit 2017 Jeep Wrangler Unlimited Sahara
    Assuming you have the factory tow package you will have the factory connector on your Jeep. Your factory 4-way should be plugged into the same connector. Removing the 4-way and adding the # HM40975-11933 will give you both a 4-way and 7-way connection. An aftermarket 4-way like the # 118416 would be plugged into the connection points behind the driver's-side tail light. If this is what you have, you would need the # ETBC7 to add a 7-way to your Wrangler.

  • 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.

I confirmed compatibility with Curt's fit guide and also with one of their technicians. The written instructions and a helpful installation article are both linked to assist you.

  • Does Pollak 7- and 4-Pole Trailer Connector have 12 Volt Hot Lead for 2014 Jeep Wrangler Unlimited
    Yes, the 7-Way part of Pollak 7- and 4-Pole Trailer Connector # HM40975-11933 has a 12 volt circuit provided that the vehicle it is installed on has that circuit active. This part is designed to work with a 2014 Jeep Wrangler Unlimited that came with a factory 7-Way. If your Jeep came with a factory 4-Way or no trailer connector then it is not likely that the 12 volt and any other circuit other than the lighting circuits will work. To add a 7-Way if the Jeep did not come with a factory...

  • Recommended Trailer Hitch Receiver for a 2017 Jeep Grand Cherokee
    The trailer hitch receiver that I recommend for you to use on your 2017 Jeep Grand Cherokee is the Curt # C13182. It is the most versatile hitch as it will fit Diesel models, SRT-8 models, and models that exclude both the Diesel and SRT-8 models of the 2017 Grand Cherokee. Your Grand Cherokee should come with a wiring harness at the rear bumper, but if it doesn't you can use the Pollak # HM40975-11933 which is like a replacement for the OEM harness and will plug right into the connector...

  • Recommended 4-way Flat Connector For 2017 Jeep Wrangler
    To add a 4-way connector to your 2017 Jeep Wrangler I recommend the T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # 118416 if you do not have the factory tow package. I also recommend the no-drill mounting bracket # 18140 and 4-way mounting bracket # 18144 to mount the connector to your trailer hitch receiver. If you do have the factory tow package you would want the # HM40975-11933 to replace you factory 7-way connector with a 7-way and 4-way. I included videos for...

  • Replacement Trailer Connector for 2007 Dodge Ram Cab and Chassis and How to Wire in Camper Lights
    First, if your 2007 Dodge Ram cab and chassis model came with a factory installed 4/7-Way then you can use # HM40975-11933 to replace it. It plugs into the factory wiring harness under the truck. What I would do is to wire the camper light wires to either a trailer side 4-Way or 7-Way connector, depending on what all functions are needed, and plug that into the trucks trailer connector instead of hardwiring it in. For a 4-Way you can use # HM48110. White is ground, brow is running lights,...

  • Troubleshooting Running Lamps and Brake Controller Output on Trailer Towed By 2014 Ram 1500
    According to the owner's manual, the fuses in F11, F29 and F30 are the ones you'll want to check. If the fuses were okay, then the most likely culprit is the trailer connector at the rear bumper of the truck. You should be able to remove the manufacturer harness from the rear of the trailer connector by sliding the gray locking tab and pulling firmly on the plug. Then, as a helper activates the running lights on the truck, take a circuit tester like # PTW2993 and probe each contact on...

  • 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...

  • 4-Way and 7-Way Trailer Wiring Recommendation for 2009 Jeep Wrangler Unlimited
    For your 2009 Jeep Wrangler Unlimited with a factory 4-way trailer wiring harness the Pollak 7-Way and 4-Way part # HM40975-11933 that you referenced would be exactly what you'd need. This will replace the 4-way you have now and give you a 4-way and 7-way.

    It is very likely the fuse if you are not getting the 12 volt auxiliary power at the 7-way of your 2020 Ram 3500, so you'll want to check your owner's manual to see where that fuse is located or your local Ram dealer can tell you. If it's not the fuse then it is going to be your 7-way connector so you'll want to use Circuit Tester # PTW2979 to check the 12 volt wire going into the 7-way connector at the plug, and behind where the 7-way plugs into the factory wiring. If there is no power...

  • 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...

  • How To Install a 7-Way Trailer Connector On a 2004 Dodge Ram 1500
    Yes, it is very possible to install/fit a 7-way trailer connector on a 2004 Dodge Ram 1500. I first recommend looking under the vehicle for a square ten pin connector. This (if present) will be located behind the rear bumper near the spare tire and will match the end of the 7- and 4-Pole Trailer Connector Socket part # HM40975-11933 which is what I recommend using if this connector is present. If you don't have the above square ten pin connector then you will need to start with a 4-way,...

  • 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...

    The trailer hitch I recommend for a 2015 Ram 1500 is the etrailer Trailer Hitch Receiver part # e98852 which is super simple to install and features bolt-on installation. Then for the wiring, I recommend the 7- and 4-Pole Trailer Connector Socket w/ Mounting Bracket part # HM40975-11933 which should be just what you need. It has both 4 and 7-way connection points.

  • 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...

  • 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....
