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.

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 Product is working perfect ! Quick and easy installation, Well built to last. I recommend it to all who need to make a connection.....



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.

  • No Power To Trailer Running Lights On a 2018 Ram
    The trailer running light fuse on a 2018 Ram 1500/2500/3500 will be located in the engine bay fuse box, a blue 20 amp fuse in the F29 cavity. If the filament is intact then you will want to test for power on the running light wire behind the trailer connector (usually brown) to see if there is power. If you have power here then replace the trailer connector with the 7- and 4-Pole Trailer Connector Socket part # HM40975-11933. If you don't have power here then there is an issue with the...

  • Replacement 7-Way and 4-Way that Fits 2012 Ram 1500
    We have the Pollak part # HM40975-11933 which fits your 2012 Ram 1500 and will give you a new 7-way and 4-way that connects to the factory wiring at the rear of the truck. It will just plug into the square connector your old 7-way is plugged into and you'd be set.

  • 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...

  • Recommended 4 & 7-Way Wiring Harness for a 2012 Chevrolet Express Van
    Good news, I can help! It sounds like your 2012 Chevrolet Express Van didn't come with the tow package. This means that there isn't a OEM factory plug for the # HM40975-11933 to plug into. If your Express Van had been built with the tow package there will be a plug at the back of the vehicle where, yes, the Hopkins 4 & 7-way plug will just simply plug into. Don't worry, if your van didn't come with the tow package, I can help you wire it up to have a 4 & 7-way plug like the Hopkins...

  • Adding a 7-Way to Bumper and Bed of a 2012 Ram 2500 that Originally Came with a 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...

  • Troubleshooting Tandem Axle Trailer Brakes
    Many brake controllers are rated for 2-8 brake assemblies, which would be 1-4 axles. In any event, I've yet to see the brake controller that shouldn't work fine with a tandem axle trailer using 10 inch brake assemblies, as long as everything is functioning properly. Which brake controller are you using? Is it throwing any error codes?

  • 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....

  • Replacement OEM Plug Adapter for 7-Way on 2010 Dodge Dakota Big Horn
    The correct OEM replacement for the 7-way wiring harness on your 2010 Dodge Dakota is the # PK11933. If your 7-way was damaged when it melted you can replace both using the # HM40975-11933. There is no option that comes with a built in T that would allow you to run 5th wheel/gooseneck wiring. The only option would be to buy a complete wiring harness and add it in like the # C56001 you were looking at.

  • Trailer Wiring Harness & Brake Control Wiring for 2016 Jeep Grand Cherokee with/without Tow Package
    If your 2016 Jeep Grand Cherokee does not have a trailer connector at the back but is pre-wired with the factory tow package then you can add a 4- and 7-Way connector using # HM40975-11933. Please note: It may be necessary to see a local Jeep dealer to activate the tow package wiring circuit. Models that did not come with the factory tow package would need to use # 118727 to add the 4-Way and then # ETBC7 to add the 7-Way. For a brake controller, if your Jeep did come with the factory...

    Because the 2008 Ford F150 with the factory wiring harness and factory 4 pole trailer connector is not wired for a 7-Way trailer connector you will need to use the Hopkins Adapter 4 Pole to 7 Pole and 4 Pole, # 37185. It retains the 4 way in the event that you would need it in the future, and it also includes the mounting bracket. The 4 pole on the adapter would plug into your existing 4 way and there are four extra wires to be wired. The extra wires are: Black: 12 volt hot lead White:...

  • Recommended Trailer Hitch and 4/7- Way Wiring Harness for a 2015 Ram 1500
    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.

  • 2018 Jeep Wrangler Unlimited Trailer Wiring Recommendation
    If your 2018 Jeep Wrangler JK has the factory tow package it would have a square connector at the rear of it for attaching trailer wiring to. For that we have the Pollak 7 and 4-way kit part # HM40975-11933 which will plug right in and be functional. The 4-way kit part # 118416 that you referenced is for versions of the vehicle that do not have the tow package, but it can fit on either style of vehicle as it installs by plugging in line with the taillight connectors on the vehicle.

  • 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,...

    If your 7-way was factory installed (you can tell by looking for the Mopar logo of the cover for the 7-way), it will have the rectangular connector used by the # PK11933 which would plug into the factory connector. For a replacement 7-way connector, use part # PK11893, or as an alternative that includes a 4-pole connector, you could use # HM40975-11933 which includes the 7-way as well as the # PK11933 harness and a mounting bracket.

Now to install a brake controller what you'll need is the part # 5506 which will complete the wiring of the brake controller to the 7-way.

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.
