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. .

This product has been great. I purchased the multi-pin trailer wiring kit, and 4-pin adapter plug. By also purchasing the vehicles specific wiring harness, instalation was quick and easy! I chose to mount this through my bumber, instead of using the included bracket for a more factory finished look, and to avoud ripping off the mount while on rought terrain. This system works great and is much more affordable than factory parts. I highly recommend! 345641

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

Although I am commenting on this product, I actually would like to comment on the following products. I purchased a brake system, tow bar, base plates and wire harness from etrailer. All of my orders were filled in a timely manner. When I reached out for technical assistance, the advisors were readily accessible. All of the products were installed by me. All of the products were very easy to install by using the video and instructions. 337851

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

Wiring harness was easy to install (less than 3 minutes) and the 7 blade to 4 pin adapter was exactly what I needed. I did not take pictures but I didn’t even need to dismantle my dash panel to instal the harnes/ cable. Easily slid behind the dash pane under the steering column and had just enough slack to plug into the Teconsha Prodigy P2 EBS controller I already had with no hanging slack to get in the way of the brake and gas pedals. Would recommend both products to anyone! 529832

  • Recommended Flat Towing System For 2017 Chevy Spark With Manual Transmission
  • According to the 2017 Chevy Spark owners manual, only the manual transmission vehicles can be flat towed. Automatic transmission vehicles can only be transported with all four wheels off the ground on a trailer. If you have the manual transmission, then I recommend the Roadmaster EZ4 Base Plate Kit - Removable Arms # RM-523185-4 if you don't have active air shutters. This installation should use the Loctite Threadlocker # LT37420. For a tow bar that either stays with the vehicle...

  • 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 #...

  • Availability of Wiring Adapter to Convert 12-Pin NATO Trailer Connector to 7-Way Blade Style
  • We do not offer any adapters to convert a 12-pin military trailer connector to a 7-way RV-style plug like that on part # H20043 but we can help you gather the parts you'll need to wire in a new trailer plug to match that on your pickup. 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...

  • 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,...

  • 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...

  • 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.

  • 7-Way to 4-Flat Trailer Connector Adapter for Volkswagen Touareg
  • We do have adapters that plug into a 7-Way on the vehicle and provide a 4-Way that can be used with the Round Tube Stainless Steel Trailer Hitch Receiver Step with LED Lights, # CR-600LED. We have some that are just 7 to 4-Way, and others that allow you to have both at the same time. I have included a link to all the 7 to 4-Way adapters below. The most economical is the Pollak 7 Pole to 4 Pole Connector Adapter, # PK12716. This is strictly a 7-Way to 4-Flat.

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 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...

For both the two and four wheel drive models, I recommend flat towing your vehicle with four wheels down as this will be the best option for frequent uses. For a flat towing setup you will first need a base plate kit such as the Roadmaster XL Base Plate Kit part # 4408-1. The Roadmaster base plate kit has a removable arm...

Which connector you need would be determined by the connector on your trailer.

Turn on the headlights, and test the pin at the 11:00 position. Then activate the right turn signal and test the pin in the 3:00 position. Turn on the left turn, and test the pin at 9:00. Each pin should make the tester illuminate as its function is activated. Then, plug in the adapter, attach the clip...

  • Replacement 7-Way Trailer Connector for 2001 Ford F250
  • Since you're needing everything from the rectangular connector back, we have exactly what you're looking for. You'll need the Tow Ready # 118243. Once you unplug the existing gray plug, this connector assembly will take its place. I've also linked you to an install video. You'd then use an adapter like # PK12716 if you needed to tow a trailer that had a 4 pole trailer connector.

Adding this harness and the relays/fuses it comes with will provide you with a 7-Way trailer connector. You could then just use an adapter, # PK12716, when you need a 4-Way. You could use # HM40975-11998 and hardwire it in to the factory wiring harness on the forward side of the truck. You would...

  • 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...

If you do not need the extra length you could use adapter # PK12716 and the trailer's 4-Way would plug into the back of it (which would be plugged into the 7-Way). I have linked video reviews of both adapters for you.

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. If the DC outlet in your truck is ran directly off of the trucks charging system, then you could use it to maintain a battery that is fully...

  • Replacement 7 Pole Trailer Connector for 2014 GMC Sierra 1500 with Factory Tow Package
  • If you need a replacement 7-Pole, RV-Style Trailer Connector because your factory connector is damaged or not working, then the Pollak Twist-in, 7-Pole, RV-Style Trailer Connector, # PK11916, which you reference, will work well for you.

  • 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.
