Quickly and easily convert a 7-pole, RV-style connector to a 4-way, flat connector with this RV connector adapter. Adapter has a non-corrosive nylon shell.by: Ralph08/22/2020
Everything worked out well. On time and fits perfect. Attach hitch setup and my new Ridgeline.
It comes with a 2" inch receiver and I have a full compliment of 1.25. stuff from my previous car. All from etrailer i must admit!
so I needed the 2-1.25 reducer, a good lock, and the 7-4 reducer for my goodies!
Thanks for the grest service

I used this outlet plug to have 12 volt to power our shuttle pump on the water wagon to pump chemicals into our chem farm mix tank works really well easy to wire and very nice looking very durable .
by: Louis 02/14/2024
It works, it doesn’t have indicator lights so it doesn’t make my Rivian think I’m towing unless I actually am. The cap is difficult to remove as it’s recessed into the unit, overall it does the job.

Works well with hitch and harness I purchased for e-trailer.

This Pollak 7 Pole to 4 Way Connector Adapter is exactly what I needed and works great. I just used it a couple days ago, and after having it for over a year, it's just as reliable as day one. I highly recommend it.
by: Rick B08/22/2023
This adapter plugs in to the OEM receptacle without any excessive effort and the flat 4 pin connector on my utility trailer also plugs into the adapter without any excessive effort. As a bonus there is a cover for the 4 pin side of the adapter to protect it the elements when not in use.
by: Craig 04/19/2024
Does what it is supposed to do. Just make sure to push it in all the way for a good connection

Exactly waht I needed
by: Ken B01/23/2017
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.

I have bought several items from etrailer that are high quality, affordable and sometimes not available in my area.

This will work on my trailer but need a plug that will fit in here so I can plug the 7 way pole into it.

I am happy to locate the plug that you need, however I was uncertain of what you are looking for. Are you looking to add a 7 way to your trailer?
by: Bob A.06/23/2023
First time buying a tow bar. Great experience with Jesse at errailer. etrailer videos are excellent.
by: Eric11/23/2023
Easy to plug in and remove. Works great.
by: Gary 12/28/2021
Received the replacement item in record time. I will check out the ability to allow the ML350 to light the LED equipped trailer.
Cheers,

Continues to work as advertised!

Good quality and the connections are snug and won’t come out too easily.
by: John08/22/2021
Once I got the receptacle for my 2021 VW ID.4 I needed the convert. This is retained nicely by the door on the receptacle so that it does not fall off enroute.
by: Mike 02/16/2023
Local Porsche dealer had been unable to get this for months for my Macan.
etrailer had it in stock for immediate shipping, and at a more reasonable price.
by: Norm C06/08/2017
Very well made adaptor, perfect fit in my Ram 1500 factory seven blade socket. Completely solved a problem I had with the truck's spring loaded socket cover breaking wires on 4 pole plugs. As always, good price and fast shipping from etrailer.com.

- Recommended Replacement Adapter to Connect 7-Way on Truck to 4-Way on Trailer It sounds like you are just needing a 7-Way to 4-Way adapter like the Pollak # PK12716. This adapter will plug into the 7-Way on your Chevy Silverado (which features 6 pins circling around a single center pin) and provide a 4-Way flat connector on the other end that will mate with the 4-Way on your trailer. We do not currently have this type of adapter available from Draw-Tite, but the Pollak model will work perfectly as a replacement. I have attached a short video demonstration on this...
view full answer... - Both Trailer Turn Singles Blink at the Same Time on a Trailer Towed by a 2008 Chevy SilveradoTypically when both blinkers flash at the same time it is either a ground problem or a corroded or miswired connector or adapter. First examine the trailer side connector and the vehicle side connector and clean out any dirt or corrosion. Also check the adapter. If that does not fix the issue make sure that the vehicle and main trailer connector grounds are attached to clean and corrosion free bare metal surfaces. Do the same for the trailer lights. A bad or weak ground can cause all...
view full answer... - 7-Way to 4-Way Adapter Recommendation for 2013 Chevy TahoeSounds like you have 7-way on your 2013 Chevy Tahoe and are looking for a way to convert it to a 4-way. For that we have the # PK12716.
view full answer... - Wiring 4 Wires on Trailer to 7-Way Connector Most likely on your trailer the brown wire is for running lights, the green wire is for right turn/brake light, the yellow is for left turn/brake, and the white wire is for ground. Because previous owners or trailer manufacturers may have installed different color wiring than what is standard, it is always a good idea to test the wires for function to be sure. You can apply 12V power to the trailer wires to see what function each of them activates. If you are wiring these to a 7-Way connector...

- 7-Way to 4-Way Adapter Recommendation for Land Rover Discovery 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.

The adapter will plug right into the 7-Way to provide you with a 4-Way flat connector at the other end that can be hooked up to a trailer's 4-Way. I have attached a short video demonstration on this adapter that you can also check out.

- Could Trailer 7-Way 12 Volt Accessory Circuit Charge Boat's BatteryThe 12 volt accessory circuit of a trailer 7-way connector is commonly used to put a maintenance charge on trailer batteries. There really is no reason you couldn't run the wire up to the battery of your boat instead. If the battery is smaller in size it might actually put a decent charge on it too. The big thing will be to come up with a way to disconnect the charge wire from the boat before backing it into the water.
view full answer... - Compatibility of Pollak # PK12716 7-way to 4-Pole Adapter with OEM 7-way on 2011 Honda RidgelineThe Pollak # PK12716 would indeed do exactly what your wanting to accomplish. The adapter will plug into the existing 7-way, and would provide a 4-pole connection that would allow you to tow your boat trailer. I've linked you to a product demonstration video, which I hope you'll find helpful.

- Adapter for 7-Pin Harness on Vehicle to 4-Flat Harness on TrailerThere are no diagrams available for this as you would need to find the functions of the wires with a circuit tester.
