I put the kit in this morning. It probably took 15-20 minutes plus the time it took to drill the hole for the receptacle itself. I have two comments. 1. I had put the module in the place directed and then realized that I had two fuse plugs in the box, so I took it back out and put those in. 2. It is quite difficult to get the "cap" off the wiring under the rear bumper. I probably struggled with that more than any other single thing. After completing the job, I plugged the 7 to 4 wire converter in and hooked it to one of my trailers and everything worked the way it was supposed to. Honda is really ripping people off with what they are doing. Please see my previous email to you. Thanks for your great product, You can bet that I'll be sending business your way, 78548

I required this adapter to convert the factory 7 pole harness on my VW Tiguan to match the 4 pole connector on my trailer. I was especially drawn to this adapter given that the vehicle harness has the Pollak name brand printed on it. The adapter "feels" like it is made well and the fit is confidence inspiring. I was quite pleased when I finished connecting my trailer through this adapter and everything worked perfectly on the first use of it. I have now towed three times (reconnecting and disconnecting after each use) and have absolutely no complaints. 87747

Purchased this for my 2010 Toyota Tacoma truck with factory towing package. Needed adapter from the RV style plug to the standard trailer 4 prong plug. eTrailer experience excellent. Plug seems to fit loose into the socket on truck but really isn't. The socket cover comes down and there is a tab on the adapter that fits into a space on the cover, preventing the adapter from coming out of the socket. Nice! 38560

7 wire to 4 wire adapter I tried using a cheaper, trailer rental outlet adapter but the fit was terrible. This is solid and worth every penny if you need an adapter. Website made it easy to find and service was solid as well. I will be back for more. I also like the wiring tips and videos. Thanks a lot! 4674

This part worked perfectly to convert a 7-pole to 4-pole light adapter for my new Nissan Pathfinder. The dealer was going to charge over $100 and this was all I needed since I have surge brakes on my trailer. If you have electric trailer brakes, this is not what you need. 127981

  • Trailer Wiring Harness Recommendations for a 2012 Honda Pilot Without a Factory Tow Package
  • There are a few different options that you have to install a 4-way or a 7-way trailer connector on your 2012 Honda Pilot. Option 1 would be to install the Tow Ready 7-Way Wiring Harness, # 118265, that you referenced and use a 7-way to 4-way adapter like part # PK12716 so you can connect to the 4-way connector from your trailer. The only downside to this set up is adding a brake controller. Since your vehicle did not come with a factory tow package, it probably does not have a brake...

  • 7-Way to 4-Pole Trailer Connector Adapter for 2013 Porsche Cayenne
  • If your Cayenne has the 7-way connector, you will simply need an adapter to convert it to a 4-pole. Because your Cayenne is equipped with a bulb-out sensor, if your trailer has LED lamps you will need to use an adapter with a resistor in it like part # TR20141. LED lamps draw very little power, and fool the bulb-out sensor into thinking a bulb is burned out. This will make the turn signals hyper-flash.

You will then need to install an adapter like # 37185. This adapter will plug into the 4-Way connector previously installed and the extra wires can be tied up out of the way for future use.

  • How to Convert the 7-Way RV Connector on a Ford Truck For Towing a Trailer with 4-Way Flat Wiring
  • You have two options for towing your trailer with a 4-Way flat connector. The easiest option is to use an adapter that allows you to plug the 4-Way connector into it and then plug the adapter into the 7-Way RV style trailer connector on your truck. The Pollak 7 Pole to 4 Pole Connector Adapter, # PK12716, would work great for this application. The second option would be to use a 4-Way Hardwire Kit, # 18252, and hard wire a 4-Way connector under the vehicle. Use the included circuit...

  • Is there an Adapter Available to Convert the 7-Way on My Jeep Commander to a Flat 4-Way
  • I assume the connector you have is a factory 7-Way. We do have adapters to convert from a factory 7-Way to a 4-Way in order to power the MasterLock camera. The adapter would be part # 47345 or part # PK12716. In case you do not have a 7-Way at the rear of the Commander, I have added a link to our wiring adapter fit guide so you can find the right adapter. One of the pictures on the product page for the 4843DAT shows the camera installed in a 2 inch hitch on a Mercury Mountaineer equipped...

  • Wiring a 7-Way for 12 Volt Power to Maintain a Trailer Battery Towed by a 2011 Chevy Colorado
  • The wiring on a vehicle and in a trailer connector is not sufficient to up-charge a trailer battery unless it is a smaller break away battery. The wiring can maintain the current charge level on the battery but a battery charger is recommended to up-charge the battery. Since your truck does not already have a 12 volt wire at the back, you will need to hardwire one from the adapter you have to the positive terminal on the battery via a 40 amp circuit breaker # PK54540 and using about...

  • Running Light Circuit Does Not Work on a 2008 Nissan Xterra with Factory Tow Package
  • If your 2008 Nissan Xterra came with a factory tow package and you wanted to convert the 7-Way to a 4-Way, you would use # 118263. However, if you are testing the 7-Way with a circuit tester like # 3808 and the running light circuit is not functioning, you will want to check the fuses/relays associated with the tow package to see if something needs to be replaced. You can use the vehicle owners manual to located all of the fuses and relays that are related to the tow package. Some may...

  • 7-Way Balde to 4 Flat Adapter Compatible with a 2008 Mercedes M-Class GL 450
  • If your 2008 Mercedes 450 M GL model has a 7-Way connector, and your trailer uses a 4-Way flat, then the Pollak 7 Pole to 4 Pole Connector Adapter, # PK12716, will work. The unit plugs into the 7-Way socket on your vehicle and the 4-pole on the trailer plugs into the back of the adapter. We actually have many of this set up. I have included a link to them below. If you are not receiving any power or signals from your vehicle side connector, that could be the reason nothing has worked....

  • Adapter for a 7-Way Connector on a 2010 Toyota Tacoma and a 4-Way on Magnetic Wiring Harness
  • It sounds like the magnetic kit you have uses a 4-Way flat connector and the truck has a 7-Way blade style connector. There is an adapter you can use. Several as a matter of fact. I have included a link to them for you to view. A simple option like # PK12716 is all you would need. But since you are flat towing, you may need some extra slack so going with a coiled adapter like # HM47065 may be the best way to go.

  • Changing a UK Wired Tailer to a USA 4 Wire System for Use with a Lincoln Navigator
  • You could make an adapter to go from the connector on your Aviator, if it is a factory 7-Way connector, to the 5 wires on your trailer.

Once the adapter is built and wired I would use the 5-Flat Trailer End 48 inch Harness, item # 20017, to splice to the trailer wiring. If you have a 4-Way connector at the...
