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.

Ask the Experts about this Pollak Custom Fit Vehicle Wiring

  • 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...

  • 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....

  • 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....

  • 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,...

  • 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...

  • What is the Towing Capacity of a 2015 Jeep Cherokee with the 3.2L V6
    If you have the factory tow package on your 2015 Jeep Cherokee Limited then you should have a wiring plug present near your trailer hitch receiver, If you do have one and you aren't sure if it is aftermarket or not then you can simply check to see how it is installed. The Pollak # HM40975-11933 is a replacement wiring kit for the tow package so you will see a square connector near the trailer hitch. Otherwise the wiring will lead up to your tail lights like the Curt T-Connector # C56208. According...

  • 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.

  • What Parts Will Be Needed to Install a Brake Controller and 7-Way Connector to a 2015 Jeep Wrangler
    You will need to install a 7-Way connector when installing a brake controller to your 2015 Jeep Wrangler Unlimited. For that you will want the Brake Controller Install Kit and 7-Way Adapter part # ETBC7. I attached installation instructions and an install video for this product as well. For a brake controller I recommend the Prodigy P2 Brake Controller part # 90885. This is our best selling brake controller because of how well it works and how easy it is to setup.

  • 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.

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.

  • 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...

  • 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...

If you do not have the factory wiring, then you will need the T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # 118727 to get a 4-way connector. Then you will need to use # ETBC7 to upgrade that 4-way to a 7-way. You will also need a brake controller for full 7-way function....

    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.

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...

  • 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...

  • 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...

  • 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...

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.

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.

    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...
