Video Transcript for Pollak Wiring PK12716 Review

Today we're going to be reviewing part number PK12716. This is the Pollak 7-Pole to 4-Pole Connector Adapter. This adapter is going to promote quick and easy conversion of your 7-pole plug to a 4-pole flat connector. You can see here that this is going to connect to the 7-pole adapter. This only got 4 pins so it's just going to send through the functions of the 4-way flat that it needs to. Then on this side, you're going to be able to undo the dust cap.

It's going to expose your 4-way flat and then you can connect your 4-way flat connector to this connection here and then have full access to the connection in the towing application that you need. It's going to allow one vehicle to tow, either campers or boat trailers, without electrical brakes. This is going to connect the ground, left turn, right turn and stop circuits. Again, it's got that nice tethered cap for protection from sand, dirt and moisture. It's all about protecting those connection point. That cap is attached to the socket, that way you don't have to worry about misplacing it or losing it. This unit is made from a non-corrosive nylon shell and insert.

It's going to be highly resistant to rust and corrosion, providing many years of use. It is small enough, that way you can leave it connected if you're just . For short term reasons or you can fully disconnect it, put this in the glove box or the center console in your vehicle or a storage compartment of your RV. You always have it handy, ready to be pulled out and use it anytime. When it comes to the application, this is designed to be used with vehicles with 7-pole connectors. Real quick, I just want to go over few of the measurements of you.

The overall length of the unit measuring from end to end is going to be about 3-3/4 of an inch and the other measurement is basically self explanatory. It is designed to fit into the 7-way connector. I just want to give you an idea of how much length you're going to have sticking out once it is connected. It's got the nice little key lock up here, that way you can make sure that it slides into the appropriate groove on the 7-way socket. Just line that up, center at the 12 o'clock position, push it in until it snaps into place and then that lid is going to snap over the end here, which is going to hold the connector firmly in place, making sure that nothing comes in between the connection points on the socket and the connector. It's got the nice pull tabs right here. That way you can get easy grip on it and easily disconnect the unit from the connection.

That's going to do it for today's review of part number PK12716. This is the Pollak 7-Pole to 4-Pole Connector Adapter. .

Volkswagen Tiguan


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

2014 Nissan Pathfinder


In a day and age when expectations are so low, eTrailer understands that the "customer service" bar shouldn't simply be laid on the ground to trip over. The product was an OEM match to my '14 NIssan Pathfinder socket - so no question about the fit or quality match. Shipping (at a premium) was easy - arrived next day (but my fault for waiting too long to order it). Well done, eTrailer...well done. 226965

2010 Toyota Tacoma


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

Shipped fast and arrived on schedule. I plugged the unit into the factory seven pole outlet on my truck and connected the four pole tailer connector and everything worked the first time. Hard to argue with success. I would recommend this product and etrailer as a company. 103066

Nissan Pathfinder


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

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 have a 2014 Buick Enclave. The dealership wanted to charge me approximately $100 for their product. I was told to try Tractor Supply and I did, but the inventory was limited and the employee was not very knowledgeable about product information and what I needed. E.trailer was very helpful, product knowledgeable and very, very reasonably priced. The product arrived quickly and works great. Thanks again. 234181

I had an old 7 way with the 4 way mounted on my truck. It broke so I replaced it with a 7 way I had laying around. I bought this to have the use of a 4 way connector. Product is as listed.

I bought this converter because the used Jeep I recently purchased had the towing package. I have a utility trailer and did not needed all the connections provided by the factory connector.

I have not hooked the trailer to it yet but my test light shows all the connections are good. Much better than the previous plug I had. Just make sure you push it far enough for the retention tab on tje cover of your main plug to keep it in place 43435

  • Needed Equipment to Flat Tow a 2001 PT Cruiser Behind Motor Home
  • In addition to the Roadmaster Tracker # RM-020 tow bar you referenced, you will need a base plate kit, safety cables, wiring and depending on the states you will be traveling in, a supplemental braking system. The Roadmaster # 278-1, which fits all PT Cruiser models, is the base plate kit you would need. The base plates use removable draw bars that makes the base plate kit practically invisible when they are removed. Quick disconnects like part # RM-201 will also be needed. The #...

  • Using 7-Way Trailer Connector 12-volt Accessory Circuit to Power Boat Winch
  • An electric winch used to pull a boat up on a trailer is designed to be wired directly to a 12-volt battery. The wire that feeds your 7-way trailer connector is too small in gauge to be able to handle the amperage draw of a winch. Attempting to use the 7-way to power the winch will almost certainly lead to blown fuses. Typically, a winch would be connected to an auxiliary battery located on the trailer. The auxiliary battery can be maintained with the 12-volt circuit from the 7-way,...

We can also offer you an easier alternative. To re-wire the trailer conector you'll need a wiring junction box # 38656, a trailer-side plug like the 4-foot # H20043 (or longer versions such as 6-foot # H20044 or 8-foot # H20046) and ring terminals like...

  • 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. If your trailer uses incandescent lamps, you can use any of the other 7-way to 4-pole...

  • What is Needed to Install a 7-Way on a 2008 Chrysler Town & Country
  • To install a 7-way on your 2008 Chrysler Town and Country you will first need to install the Tow Ready Custom Fit Vehicle Wiring # 118552 that you referenced. I attached installation instructions and an installation video for you to check out. If there are not trailer brakes on the trailer you plan on towing you could just use a 4-way to 7-way adapter like a Pollak 7 Pole to 4 Pole Connector Adapter # PK12716 and you would be ready to go. If you have trailer brakes you will need to...

  • Trailer Taillights Not Working on a 1998 Chevy Tahoe Everything Else Works Except Running Lights
  • It sounds like the tow package running light fuse is blown. There is a power distribution panel under the hood. When you remove the cover there will be a legend on the underside indication where the tow package fuses are located. The running light fuse for this circuit should be located in this panel also. If a tow package fuse is blown check the trailer wiring for a short on the taillight circuit before reconnecting it to the vehicle. If you find that the fuses are good, the next...

  • 7-Way to 5-Way Adapter for a Honda Pilot with 7-Way and Trailer with 5 Pin Connector
  • A 5-pin round connector is pretty rare, are you sure you do not have a 6-pin, 5 pins in a circle with one pin in the center? Having both trailers work with your 7-way connector on the Pilot will be pretty easy. You will need a 4 pole to 7-way adapter, part # PK12716. This will allow you to tow the trailer with the 4 pole connector with no problem. For your trailer with the 5 pin round connector, you will have to make a wiring modification to the trailer because of the separate brake...

  • 2005 Nissan Titan Trailer Lights Not Working Using Tow Ready Wiring Harness
  • If your 2005 Nissan Titan came with a tow package and a factory installed 7-Way trailer connector then it may be easier to use a simple adapter, like # PK12716, to go to a 4-Way. If your truck did not come with a 7-Way at the back, then you would probably need to add some relays, # C57000, to make the wiring fully functional. The relays are required for trucks that did not come with a factory tow package.

  • 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. I would use the Pollak Black Plastic, 7-Pole, RV-Style Trailer Connector, item # PK12706, along with the 5-Flat Vehicle End 72 inch Wiring Harness, item # 20016, to build an adapter. 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...

  • Truck Bed Wiring for a Slide in Camper on a 2008 Nissan Titan
  • With a camper in the bed, and an in-line wiring harness connected, you will retain the use of the 7-Way at the rear of the truck (if it has a factory tow package) but you will not be able to use both at the same time. Either the camper can be plugged in or the trailer. Trying to use both at the same time will overload the electrical system in the truck. If your 2008 Nissan Titan has a factory tow package, what you can do to provide wiring for the truck bed camper is install the Draw-Tite...

  • Trailer Brake Lights Do Not Work When Connected have a 96 ranger with seprate turn and brake
  • Whenever any type of adapter like # PK12716 is used to mate different types of connectors on the vehicle and trailer, connection problems can develop because of all the extra contact points. The best way to go is to install a new connector on the trailer that directly matches that on the tow vehicle so that you can avoid using an adapter. This is easily done by using a junction box like # 38656 and a new 7-way plug like # H20044. All you need to do is verify the function on each trailer...

  • Light Kit Recommendation for a Motorcycle Carrier
  • We have a light kit that could possibly be made to work on your motorcycle carrier, part # 98174LED. Without knowing what motorcycle carrier you have it would be hard to say exactly what you would need to do to mount it to your carrier. The lights of this kit are considered submersible meaning they are waterproof. This kit is designed to attach to a 4-way connector, so you would need a 7-way to 4-way adapter to allow you to connect your trailer connector to this light kit. For that you...

  • 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...

  • Matching Wires From a 4 Way Connector on a Trailer to a 7 Way Adapter
  • It sounds like you are using a 7-Way adapter, like part # PK12716, to connect to your 4-Way connector on your trailer. In this case the wiring is not going to match up by color except for the white ground connections. The red wire from the adapter will connect with the yellow wire on the 4-Way connector, the brown wire from the adapter will connect with the green wire from the connector and the green wire from the adapter will connect with the brown wire from the connector.

  • Is Hopkins # HM47065 7-Way to 4-Pole Adapter Compatible with 2015 Toyota Tacoma
  • The Hopkins # HM47065 is not a vehicle specific item, it will work in the 7-way of any vehicle and allow a trailer or flat towed vehicle with a 4-pole flat connector to receive lighting signals from the tow vehicle. The # HM47065 would typically be used for flat towing a vehicle, while an adapter like part # PK12716 would usually be used for a trailer. If you'd care to see a product description video featuring the Hopkins Adapter, please click the provided link.

  • Flat Tow Wiring Recommendation for a 2015 Jeep Cherokee
  • First thing you want to do is test your 7-pin with a circuit tester like part # 3808 to determine if it has separate or combined trailer wiring. Most likely if you have a standard 7-way at the rear of your RV it has combined circuits so that it would be compatible with most trailers. Use the chart I attached to compare what you have to what the standard wiring patterns are. For a diode tow bar wiring kit you would want the # RM-154 and then the 7-way to 4-way adapter part # PK12716. If...
