Video Transcript for Pollak 7 Pole to 4 Way Connector Adapter Review

Andy: Hey guys, it's Andy here at etrailer.com. Often times, we get questions from our customers and they want to know how they can convert their seven pull on the back of their truck or vehicle into a four pull. Several reasons for that. Maybe you want to haul a utility trailer that only has a four pull connector. Maybe you've got some type of accessory on the back of the cargo carrier, maybe a hitch cover, and you want it to lit. This is gonna help to solve that problem without doing any modifications to your vehicle's wiring.

Not gonna have to cut. We're not gonna have to splice. We're not gonna have to modify anything. Basically with this adaptor, we can plug it into the back of the vehicle and it's gonna go in like any normal seven pull would. Push it in so that the tab on the gate engages the tab on the plug.Once the cover's off, that gives us our four pull plug there very easily accessible.

It's gonna have ground, running lights, left turn and brake, and right turn and brake. So we can simply take that trailer that we couldn't haul before, get that plugged in, we'll be ready to hit the road safely. Now working lights on a trailer are very important to indicate which direction you intend to go. It's gonna help a lot of people around you. Also in cargo carriers when you stack them up and they kind of block your tail lights, it's gonna indicate to people which direction you're going and when you're hitting your brakes.

Just makes it safer for everybody involved.Now this adaptor gets excellent reviews from our customers. It's probably one of the more popular ones that we carry. It's nice and solid. It has a good grip on the back. Now overall, this is gonna be an excellent solution, but any time we're using a seven pull to plug into a truck, plugging into the back of our trailer.

We always want to use some dielectric grease. This is available on our website if you don't already have some, but by adding that in, you're gonna reduce any moisture getting into our contact points which holds dirt. Once we've got dirt and moisture in there, that generally leads to corrosion. So this is gonna eliminate that problem and make sure that you have a good connection for both your truck side and plugging the trailer side in.If I was in need for an adaptor like this, I would definitely pick one up. I think it's a really good option. There are adaptors similar to this that offer a fifth pull. That would be really handy if you we're gonna be adding backup lights to a trailer and you wanted them to come on when you hit reverse, or also in marine trailer applications when they have surge brakes. Not all of them are designed this way, but some of them are designed with an electronic lockout triggered by that reverse signal. So as you go to back up, it won't let the fluid pass and lock up the brakes. So if those two things are on your mind, pick up a seven to five. It's gonna help you out a little bit there, but outside of that I would definitely own this one and I would definitely use it if I had the need.

The adapter is great. Works like a charm but more importantly, the price I paid thru etrailer was a fraction of what I'd have had to pay downtown at the autoparts store. These guys are great. I've ordered a lot of things for my 2017 Tacoma and the parts always worked great and were priced very competitively. BTW, their website rocks. Easy to get the right part for the job with their information. 694402

This is a very nice, high quality adapter plug for my trailer towing. This was shipped promptly and packaged very well. I am very pleased with my plug, almost as pleased as I am with my plug of "Days Work, Chewing Tobacco" which I like very much. Thanks, John 580289

This adapter comes in real handy when you get ready to leave the boat ramp after a great day on the water and find your lights not working. Unfortunately the little flat connector looses contact occasionally because of wear and corrosion. Just plug this adapter into the barrel socket (on most trucks) and now there is a fresh and clean connection. I have only used mine twice so far to get me home, so I could repair my truck plug, but I was real happy to have it when I needed it. 369481

Ask the Experts about this Pollak Wiring

  • How Do I Convert My 2006 Toyota Sequoias 7-Way Connector to a 4-Way Connector
    All you would need is a Pollak 7 Pole to 4 Pole Connector Adapter, part # PK12716, to connect your 4 pole boat trailer to your 7 pole 2006 Toyota Sequoia. You will simply plug your 4 pole trailer connector into the Pollak 7 Pole to 4 Pole Connector Adapter, part #, PK12716 and then plug that into your Sequoias 7 pole connector and you will be good to go.

  • Compatibility of 7 Pole to 4 Way Adapter PK12716 with 7-Way Vehicle Connector PK11916
    Yes, the two Pollak parts you referenced are compatible. The Twist-In 7-Pole Vehicle Connector # PK11916 will work fine with the 7 Pole to 4 Way Adapter # PK12716. The adapter will fit the 7-way connector and provide you with a connector in the 4-pole trailer wiring format which includes basic lighting signals for stop, turn and tail lights. The signals for the other circuits on the 7-way (12V power, trailer brakes and reverse lights) will not be transmitted on the adapter's 4-pole output side.

  • 7-Way to 4-Way Adapter Recommendation
    I looked up the part number you mentioned and it is basically just a 7-way to 4-way adapter for Ford 7-ways. For that all you would need is the part # PK12716 which is also made by Pollak.

  • Adding 4-Pole Trailer Connector to 2009 GMC Sierra Equipped with Factory 7-Way Connector
    There's a few different ways you can do this. For the easiest choice, you can use a simple adapter like # PK12716. Simply plug it into the 7-way then plug the 4-pole connector for the trailer into the adapter. Another option would use the # 118384 4-pole connector. This 4-pole would plug inline between the vehicle wiring harness and the twist-in # PK11916 7-way. This would provide you with an always functioning 4-pole connector, and you wouldn't need to fool with an adapter.

This will simply connect to the 4-way flat giving you the functions of running lights as well as brake lights and turn signals on the trailer.

  • Adding a 4-Way Trailer Connector to a 2014 GMC Sierra 1500
    If your 2014 GMC Sierra came with a factory 7-Way you can use # 41155 to plug in a 4-Way in its place. Or you can use an adapter such as # PK12716. If your truck did not come with any trailer connector you would have to contact a GMC/Chevy dealer for the proper parts since there are currently no aftermarket 4-Way harnesses confirmed to fit your truck.

Both plug in to the socket on the vehicle and provide a receptacle for a 4-pole flat trailer connector. The difference between them is that the Pollak adapter is a single piece while the Hopkins adapter uses two separate sections linked by a short length of wiring. In some applications these...

If you wanted to use the factory 7-way you could use the 12-Volt Power Inverter Adapter, # HM11147650, to provide DC power to the inverter.

    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...

That being said the connector would NOT match up to the 4-way on your Jetta to the 7-way on your trailer. You would need the part # 37185 instead. You will notice that this adapter has a socket instead of a male 7-way. This would be the configuration that would work for your application.

In some cases, the load resistors in the adapter are not enough. In those cases additional load...

This way your trailer can easily be towed by any vehicle with a 4-way. I attached a diagram that shows how this converter installs onto a trailer's taillight circuit.

    Wire colors don't always match what they are supposed to as a lot of manufacturers use their own guide which isn't the same as the standard. Especially on 7-ways since the wires aren't normally seen. If your 7-way is a factory 7-way that hasn't been tampered with I would assume that the wiring is to the standard that most 7-ways are. The part # PK12716 is a 7-way to 4-way adapter that will plug in and give you a functioning 4-way then.
