• Does the Pollak 7 Pole to 4 Way Adapter PK12716 Work w/a Pollak 7-Pole Connector?
  It sure does Jerry. The Pollak 7 Pole to 4 Way Connector Adapter item # PK12716 is going to plug right into the Pollak 7-Pole RV Blade-Style Trailer Socket item # PK12-707E. It'll adapt the 7-way to work with 4-way connectors for trailer lighting or accessory lights. What are you connecting to your 7-way that has a 4-way connector? You can add this information, along with any other questions you have, where it says Add Comment.

• How to Make 7-Way Adapter for Scooter Lift to Plug Into 7-Way on Honda Ridgeline
  The adapter part # PK12716 that you referenced only carries turn signal circuits so while I have a solution that would work, this would not be it. Instead you would want to wire the scooter lift power wires to a 7-way like part # PK12706. The ground circuit will be the pin in the 5:00 position and the 12 volt power would be in the 11:00 position.

• Troubleshooting LED Light Bar Not Working for 2022 Chevy Silverado 3500
  The newer GM trucks have a PWM system that makes it difficult to use other products like LED light bars. For your application I recommend using the Furrion 7-Way Adapter # FR87PR along with the Pollak Adapter # PK12716 to match with your light strip bar.

• Troubleshooting Trailer Tail Lights Not Working On a 2012 Cadillac Escalade
  As your trailer works on other vehicles and your 2012 Cadillac Escalade has the factory tow package I recommend starting by checking the fuses. On your engine compartment fuse box fuse number 1 is for the right trailer brake/turn signal. Fuse number 3 is for the left trailer brake/turn signal. And fuse 25 is for the parking/running lights. If the fuses are all good you will want to test your 7-way with a Test Light # PTW2993 to verify power is getting to the 7-way. I have included a image...

• What is Simplest Magnetic Tow Bar Lighting Solution for Tow Vehicle that has 7-Way
  Hey David, to make your life as easy as possible I would go with a magnetic lighting kit like the part # PE26UR which has a 4-way flat connector which will allow you to use an adapter like the part # PK12716 and not have to do any wiring or splicing. To use the part # 337TL257M you'd need to cut off the 4-way round and wire in the part # PK12706 instead.

  Since you said your 2018 Jeep Grand Cherokee already has a 7-way connector, and you are looking to tow a trailer with a 4-way connector, you just need an adapter.

• Recommended 4-Way Connector for a 2018 or 2020 Ford F-150 to Power a LED Light Bar
  Hey Keith! Not sure if you have a 2018 or a 2020 F-150 but I know you don't have a 2028. If you do not have a trailer connector on your truck you'll need to install the Curt 4-Way Flat Trailer Connector w/ 60" Harness item # C58044. There are no custom fit harnesses if your truck didn't come with some form of a trailer connector from the factory. If your truck does have a 7-way connector, you'll be able to use the Pollak 7 Pole to 4 Way Connector Adapter item # PK12716 to power your LED...

• Flat Tow Wiring Recommendation for Dolly Towing a 2018 Cadillac XT5
  Hey Mike, thanks for reaching out! I have 2 different options for you to look at, and it really just depends on what style you're looking for: The Heavy Duty Magnetic Tow Lights # TL21RK are wired and will work with your 7-Way if you use the Pollak Adapter # PK12716. For a wireless option we have the Custer Wireless LED Tow Bar Light # LIW-LDTL-7B which plugs in without the adapter and obviously doesn't require you to run wiring along your vehicle and make sure it isn't blowing around...

• Hitch, Wiring, and Brake Controller for 1997 K3500 Dually
  Hey Brian! For 7-way wiring to go with your Curt # C15325 the best option is the # 20023. This is only a 7-way so you can either use an adapter like # PK12716 or swap out the connector for one that fits a USCAR connection like the Curt Dual Connection Socket # C36GJ. For a brake controller I recommend the Redarc Tow-Pro Liberty # RED52VR. The Liberty is simple, reliable, and won't take up space in the cab of your truck. The main unit installs behind the dash so only the control knob is...

• Is There a 4-Way Trailer Connector For 2024 Ford Ranger
  Hi Tom, There is always the option for you to use a universal, splice-in 4-way for the 2024 Ford Ranger, the Curt Powered Tail Light Converter with 4-Pole Flat Trailer Connector # C59236. As for the # C86RV, it hasn't been made yet so there isn't any specific info but if it's like the previous offering from Curt then it's just going to be a standard 7-way, so if your trailers all use a 4-way then you would need an adapter, the Pollak 7 Pole to 4 Way Connector Adapter # PK12716.

• How to Power the Thule License Plate Holder for Bike Racks w/ a 7-Way Connector
  Hey Joseph! The Thule License Plate Holder for Bike Racks item # TH35JV uses a 4-way connector to power the lights. Since you've got a 7-way there are two options you can use. If you're going to be using your 7-way connector along with your bike rack you'll want the Hopkins Endurance Multi-Tow Trailer Connector Adapter item # HM47570. If you're just plugging in the license plate bracket you can use the Pollak 7 Pole to 4 Way Connector Adapter item # PK12716. Both of these will plug...

• Which Stealth Hitch Option for Towing Small Boat With 2021 Hyundai Palisade
  The # 391CONVPT5L Stealth Hitch you'd looked at doesn't include the receiver that's designed for towing, it's meant for hitch mounted accessories only, but there are options that would allow you to tow your boat. To tow your boat, there's a couple ways you can go to upgrade to make that possible. You could use the part # 391CONVPT5L hitch, add the # 391BMU5L ball mount and a # 63845 2-inch trailer ball and the # CU94FR 4-pole trailer wiring harness, which would provide you everything you...

• Recommended Trailer Wiring Harness for a 2024 Tesla Model Y
  It depends on what trailer you'd consider to be "most" trailers, but with a Tesla you're going to be pretty limited so I'll assume it's nothing with brakes. So with that being said, we have the ZCI Circuit Protected Vehicle Wiring Harness w/ 4-Pole Flat Trailer Connector and Installation Kit # 119250KIT, which is a custom fit harness that'll simply plug into your factory wiring. This is a 4 pole wiring harness which is pretty much that standard on every small trailer. It's also worth...

• Recommended Trailer Wiring Harness For A 2021 Chevy Traverse
  Hi Motty, 2021 Chevy Traverse's have a factory connector at the back to plug into so you can go with either a 4-pole # C56394 or 7-way # C56393 connector depending on your needs. Personally, I'd go with the 7-way and if you need to connect to a 4-pole trailer wire harness you can just use an adapter # PK12716. Having a 7-way will allow you to install a brake controller and tow trailers with brakes so it's just going to offer more versatility. To mount the 7-way connector I recommend...

• Adapter For 6-Pin Round Socket On Vehicle And Trailer With 4-Flat
  Hello Willy, thanks for reaching out. If what you have on your truck is a 6-pin round plug like part # # PK12720 (pictured below), you can use the adapter part # PK12717. This will plug in the 6-pin round plug and allow you to hook up the 4-flat plug on your trailer. If the plug on your truck is actually a standard 7-way (also pictured below), what you will need is the adapter # PK12716. Leave a reply below with any other questions or comments and I am happy to get back to you.

• Adding 4-flat/7-Way Combo Plug To 2022 Honda Ridgeline With Factory 7-Way
  Hey George, thanks for reaching out. You have a couple of good options to add a 4-flat connection alongside your factory 7-way on the Ridgeline. The first option is to replace the existing 7-way socket with a combination 7-way/4-flat unit. Since the factory 7-way on your Ridgeline uses a standard USCAR connector, you can simply unplug the original socket and plug in a combo like the Curt Dual Connection Socket # C36GJ. This keeps everything clean and factory-looking and gives you both...

• 7-Way to 4-Way Adapter for 2024 Hyundai Palisade
  Any 7-way to 4-way adapter will work with the 7-way on your Palisade. The # PK12716 you were looking at is usually what I recommend since it has a low cost and small size to store in the vehicle. If you want one that also acts as an extension you can use the # HM47065.

• Options For Replacing A Broken 7-Way Connector
  Hello Evan. I do have a solution for you, but I am afraid we do not offer a product that will fit your exact description. We do offer a few 7-way extensions that could potentially be used. Something like the TorkLift Wiring Harness Extension # TLW6021. This will plug into the old 7-way and give you a new 7-way plug. It is 21" long though, so you would have to come up with a way to hide all the extra cord. You can use that with a bracket # A10-9394VP for a clean installation. Keep in mind...

• Wiring Harness For 2025 Cadillac XT5 With 4-Flat And 7-Way
  Hi Ed! I wasn't sure which hitch you were looking at, but I recommend the etrailer Trailer Hitch Receiver - Custom Fit - Matte Black Finish - Class III - 2" # e62AR. The matte black finish helps hide it better than glossy options, which I think looks more stock-ish. The wiring will be a little more difficult, but not overly so. There isn't a wiring harness for your '25 Cadillac XT5 that has both the 7-way and 4-flat, but it is possible to get something that does. You will need to start...
