Pollak Metal 7-Pole, RV-Style Trailer Connector - Trailer End - PK12702

Average Customer Rating:  4.7 out of 5 stars   (49 Customer Reviews)

This standard, RV-style 7-pole connector provides a secure connection between your trailer and tow vehicle. Traditional metal construction provides maximum resistance to weather and corrosion.


There are a few that because the plastic insert are not precise, we had to insert a shim to make a good connection. Also, it needs a pull handle on the other side so you can pull out of truck equally. We need something more durable and easier to use all day. Good if you only have to touch once a day. We are using multiple trailers all day.

You shouldnt have to be using a shim. I am having our customer service team reach out to you about this.

I purchased this trailer connector to build a wiring harness for an older boat trailer that has a non-standard wiring layout. I have a much older Pollak 7-pole connector for another trailer, and this new one appears to be identical in every respect, including quality. It is good to see consistency over the years.


Amy helped me out and spent an plus looking for the right solution


Seems to be of good quality. I replaced a plastic one that was broken. Yep, if it's plastic it will break....


really not sure now after a year how it all went down...I think I ended up using it for my trailer b/c I had to chop off the molded plug that came with my trailer to do a upfit and consequently needed a new plug. Still in use so I guess it's doing it's job.


This was a substitute for another product but I prefer the plastic one for my application.


Will hold up a lot better than those plastic one's want have to be replacing it ever couple of years.


Part was exactly what I wanted,,,and arrived on time

Works perfectly. Thank you
James - 08/25/2021


Exactly the product I needed! High quality and far better than the plastic ones on the market!




These plugs are the toughest plugs i have found. I own a small rental company so my trailers take a lot of abuse.

Paul Schroeder


E trailer and items soldThe products were accurately described, I got just what I was expecting. I can not give long term performance evaluations but so far the parts fit perfectly and are doing just fine.
The communication has been excellent, and the shipping was fast.


Good product


The wire lock swivels even after being tight on the wire. The terminals are cheap and bent and twist when tightening. I bought the metal one thinking the quality misht be better. It does not seem like it.


Only "metal" plug end I've found. The plastic ones don't hold up. I've used many types to no avail. So went with this. Wish it was a stainless housing though. The plastic pin casing is only held in by one set screw on one side, so it sits very loosley in the housing. We'll see how it holds up to time and use.


Connector connector doesn't rust, break, corroded and terminal don't short out like the plastic ones do.


Easy install super tight connection way better than any other plug I have bought hopefully this product will not have to be replaced every six months like the Hopkins brand


Both male and female connectors are good quality!


Received exactly what I ordered...very fast delivery. Thank you for your prompt, accurate service.

Very happy with it. Has held up well and works as I would expect it.
Tom B - 09/27/2017


good replacement for the crappy plastic ones that always break. price is well worth it.


Product is as described and shipping was very speedy.

Holding up well. I use it every other weekend.
Tim Z - 11/07/2018

Delivered quickly and was exactly as ad vertised!

  • How Long Is the Pollak Metal 7-Pole, RV-Style Trailer Connector Part # PK12702
    The Pollak Metal 7-Pole, RV-Style Trailer Connector part # PK12702 is 2-3/4" long from the face to the rubber boot on the back. This is currently the shortest trailer connector we offer so if you still do not have enough room you might want to consider moving the frame bracket for the weight distribution system just a bit. The frame brackets usually have a range that they can be installed in rather than a set point anyhow.

  • Replacement Metal Trailer Connector for a 2018 Ram 4500
    Yes, we do carry a metal 7-blade vehicle side trailer connector in the Pollak Metal 7-Pole, RV-Style Trailer Socket part # PK12703. In order to install this you will need to cut off the the connector you have now and hardwire the above in but there is no other way around this. The matching metal 7-blade trailer side trailer connector for this is the Pollak Metal 7-Pole, RV-Style Trailer Connector part # PK12702. The above is the only metal 7-blade vehicle side trailer connector we offer.

  • Correct Wiring Adapter for Truck with 7-Pole Connector to Trailer with 4-Pole Flat
    The Pollak 7 Pole to 4 Way Connector Adapter, part # PK12716, is exactly what you need. If you have the standard connector for a Ram, there will be 6 flat pins that go around, in addition to the center pin, for a total of 7. I've attached a photo that shows the truck and trailer end connectors that will work with this adapter. Hopefully that clears things up. If this isn't what you have, I've attached a link to our Wiring Adapter Fit Guide which uses actual connector photos to easily help...

    We do not have an adapter that will work, but we do have the parts to make your own. This will allow you to plug in your square 6-Way trailer connector to the round 7-Way vehicle connector. You will need to purchase two parts to make this work for your Jeep Grand Cherokee. First you will need the 6-Pole Square Trailer Wiring Connector Kit, product number 37995. You will be able to split this item, and wire it to work with the 7-Way Trailer Connector, either metal, item PK12702, or plastic,...

  • Protecting a Trailer Side 7-Way Connector from Corrosion
    There isn't a cover for a trailer side 7-way connector. But what you can do is use some dielectric grease, # LT37534, to repel moisture and protect the contacts inside the connector.

  • Are Available 7-Way Connectors Wired for US Made Trailers
    The 7-Way trailer wiring sockets we have available such as the Pollak Metal # PK12703 referenced in your question do indeed feature the standard US pin configuration. I have attached an image that shows the pin locations and functions that you can use for reference. This is a 7-Way for the vehicle end. For the trailer end you will use # PK12702. Keep in mind though that the actual wire color used on both the vehicle and trailer can differ. Because of this it is always best to test the...

  • Tips for Getting a Large Trailer Wire to Fit into a Small 7-Way
    If you are having a hard time getting the connector wires from your trailer into the replacement 7-way that you have there are a couple things you can try. The first thing I would try would be to twist the end of the exposed wire until it will not twist anymore. This will make the wire as skinny as possible and give it the best chance at fitting in the slots. Or you could use ring terminals like our part # DW05705-1 to attach to the wire, and then attach the ring terminal to the 7-way....

  • Recommendedations To Change 4-Way Connector On Trailer To 7-Way Connector
    It sounds like you want a permanent change from the 4-way connector to a 7-way connector on your trailer. We carry trailer-end 7-way connectors and the one I recommend is the Pollak Metal 7-Pole Connector, part # PK12702. This is a blade-style connector. If you have a round-pin connector on your vehicle I recommend part # PK11700. This would require cutting the 4-way connector off your trailer. You would need to test the wires on the trailer using a 12V power source to see what each...

  • Wiring an In-Bed Northland Camper Using Camper and Truck Existing Wiring in a 2012 Dodge Ram 3500
    My recommendation would be to determine how your camper is wired and install a RV-Style trailer 7-pole connector on your camper wiring. Then use your existing 7-pole connection at the rear bumper of your truck to install an in-bed connection point to supply power to your camper. To begin I suggest determining how your camper is currently wired. To do this you will have to apply 12 volt power to the lines that you have mentioned that are coming out of the camper in the front left corner...

  • How to Install 7-Way Metal Trailer Connector and Wiring Harness for a 1999 Jeep Wrangler
    You definitely can hard wire the part # PK12703 plug to your Wrangler, we have the wire and can help you do it. However, the easiest way to wire your Jeep with a 7 way connector would be to purchase a standard 4 pole connector (just plugs in behind the taillight assemblies) either # 42615 or # 118409, and upgrade with an # ETBC7 wiring kit. This kit has all parts necessary to install the 7 way connector on your vehicle and has the wiring for trailer brakes and auxiliary power to the trailer...
