Video Transcript for Pollak Custom Fit Vehicle Wiring - Trailer Hitch Wiring - HM40975-11933 Review

Today we're going to review part number HM-40975-11933. This is the Pollak seven way and four way trailer connector socket with the mounting bracket and the Dodge, Chrysler OEM plug adapter. Now this part will include everything shown here on the table, has the seven and four way trailer connector. Basically, you can see there's your seven way, there's your four way. It does come with the mounting bracket. Now, the connector itself is a high impact, ABS plastic construction, has a stainless steel spring, right here in the middle, that operate the covers, make it very easy to open, and strong to close it.

Even on the covers right in here, you can see there's a rubber gasket on both of them. When it closes, that rubber gasket will provide a weather resistant seal against those terminals, so it keeps it protected from the elements. This part right here is a Dodge Chrysler OEM plug adapter, for a quick connection. This part would plug into the back of the seven and four way. This part is designed to fit the connector that is factory on your Dodge or Chrysler vehicle. The mounting bracket, it's made for an easy snap in installation.

It's a black, epoxy coated, steel construction. Application on this again, this part right here is designed to replace your factory seven way connector on a lot of Chevys, Fords, GMC, Nissan trucks and SUVs. It also can be used to add a connector to the 2003 and newer GM trucks and SUVs. Then this part right here is an exact replacement for Chrysler, Dodge vehicles that come with the seven way socket from the factory. Just to show you real quick how this would go, and again, it comes with two mounting screws for attaching your mounting bracket to your vehicle. Basically, you'll see these brackets or snaps right here on the side. You just line it up with there and when you push it in, you can see that they clip into place, holds the socket sturdy on the mounting bracket.

Then what you'll do is take this end, mount it to the plug that's underneath your vehicle on your Dodge or your Chrysler, run this right to here to where it lines up. Line it up, push it in. You'll hear it click into place. Then just push in your grey lock there and that will lock it on to there so it won't come off. Then with it all connected, you're ready to go and be able to use your seven or four way connector.

That should do it for the review of part number HM-40975-11933, the Pollak seven and four way trailer connector socket with the mounting bracket and the Dodge, Chrysler OEM plug adapter.

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. 634224

Have a 2008 F-250 . Can I just order the 7 pin and 4 pin connector without the bracket and pigtail. Thank you

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.

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. 513680

Do you have a question about this Custom Fit Vehicle Wiring?


  • Replacement Mounting Bracket For A 7 And 4-Pole Trailer Connector Socket
  • Yes, the correct bracket you are requesting for the 7- and 4-Pole Trailer Connector Socket part # HM40975-11933 is our Replacement Mounting Bracket for Hopkins part # HM40978. 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.

  • 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 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...

  • 7 and 4-Way Recommendation for 2004 Jeep Grand Cherokee without Trailer Wiring
  • You will need to start with a 4-way (if you do not have one). For that you would want the # 118369. 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 will give you both a 4 and 7-way too like you are wanting. 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.

  • 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...

  • Will 7- and 4-Pole Trailer Connector Socket # HM40975-11933 Fit a 2018 Jeep JK Wrangler Unlimited
  • 7- and 4-Pole Trailer Connector Socket # HM40975-11933 will fit your 2018 Jeep Wrangler Unlimited JK as long as it has the factory tow package. I am assuming that it does since it came with a 4-Way connector but it would be worth asking the dealer if it is equipped with the factory tow package. They can usually just run the VIN in their computer system to determine how a vehicle is equipped. If it does not have the factory tow package then to add a 7-Way you will need # ETBC7. I have...

  • Recommended Trailer Hitch Receiver and Wiring For 2017 Jeep Grand Cherokee
  • For your 2017 Jeep Grand Cherokee, the Draw-Tite Max-Frame Trailer Hitch Receiver Class III - 2" # 75699 you referenced is a confirmed fit. It does not include the wiring. The prewired aspect you are most likely referencing is that someone told you is a wiring harness from the factory that you will connect other wiring to. I recommend using the Pollak 7- and 4-Pole Trailer Connector Socket w/ Mounting Bracket, Chrysler/Dodge OEM Plug Adapter, # HM40975-11933. For a ball mount, I...

  • 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.

  • 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...

  • Brake Controller and Weight Distribution Recommendation for 2015 Jeep Wrangler Unlimited
  • Since your 2015 Jeep Wrangler Unlimited came with the factory tow package the wiring harness you will want is the part # HM40975-11933 as it will give you both a 4-way and a 7-way. 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 you check out the install video I attached below you'll see exactly how we did this on a similar 2017 Unlimited like yours. For a brake controller I would recommend...

  • Recommended Trailer Wiring for 2017 Ram Promaster 2500
  • For your 2017 Ram Promaster 2500, the Pollak 7- and 4-Pole Trailer Connector Socket w/ Mounting Bracket, Chrysler/Dodge OEM Plug Adapter # HM40975-11933 is what you need. 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...

  • 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...

  • 4-Way to 7-Way Adapter Recommendation for a 2015 Equinox LTZ
  • We have exactly what you would need. For an adapter that would convert your 4-way to a 7-way for just controlling the taillight functions of the trailer you would want the part # 37185. The current 4-way you have on your 2015 Chevy Equinox will plug right in to the 4-way of this adapter and it will be ready to go. This comes with a bracket that will allow it to easily be mounted to your bumper. Check out the install video I attached for more info as well.

  • Replacement 7-Way Connector For 1997 Dodge Dakota
  • The first thing you will want to do is find out what is causing the issue with the 7-way connector you have installed on your 1997 Dodge Dakota. You could possibly have moisture or corrosion inside the 7-way connector or in the OEM vehicle harness connector your 7-way is plugged into. I would recommend first carefully inspecting the 7-way connector contacts for any greenish or whitish discoloration that could indicate corrosion, and clean the contact surfaces as needed. If the contacts...
