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. .

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
Every item that was purchased was installed within 15 minutes with ease no PROBLEMS at all LOOKS ausume on the truck and adds value also I will buy from etrailer again price was right and super fast shipping. Thanks again etrailer 68730

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

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

My plug was shipped the same day I ordered it and was received on the day they said I would get it. Plug is very good quality and I'm pleased with my purchase. I had bought a trailer wiring harness at the same time and was very pleased with that also. 137606
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

I needed the Pollak 7 Pole to 4 Pole connector adapter to connect my Thule 684 Terrapin cargo box to my 2012 MB GL 450. I hooked it up last night and the adapter works perfectly. All lighting functions on the Thule are working as designed. 88500

I recently purchased a new GMC truck and it had a factory installed towing system. It had a Pollak 7 pole socket installed at the factory. I needed an adapter so I ordered this one. It is the exact perfect adapter I needed to do the job. 13141

Perfect - fit just like you said. I am not so mechanically savey but your descriptions of "if you have this, you can use this" made it so simple, and shipping was super fast. Dealt with before and will deal with again! 9007
Purchased two new trucks that came prewired for RV plugs and the ole trailer had a 4 pin flat plug. This worked like a charm and saved me alot of time having to rewire the trailer with an RV plug. Well worth the money. 40831

A high quality device at a reasonable price. My problem was understanding which type of adapter to purchase. The web site does not help much. The wiring diagram I received after the sale was fantastic. 126377
This adapter is exactly what I needed. I explain my problem to sales rep Alicia G and she knows what I needed. I plug it in to my 7 pin harness and than my 4 pin boat trailer. And guess what? It works!!! 83218

Plugs right into the 7 pin plug and has place on back to adapt to the 4 wire flat. Simple and straightforward without the corrosion prone adapters I've worked with in the past. 12752
