This looks to be a decent quality part. It works as it should. I wanted a close as possible look for a 71 c10 and this is about all that is available. Not only would the plastic not suit the older truck, they are more bulky and plastic breaks if you bump it. I’m satisfied so far.

Love the look of that type of truck! It would be fun to see the whole truck if you felt like sending in another photo :) I think this new connect will blend right in.

by: Linda 05/09/2024 One Year Later

Works great and heavy duty. Bought this due to our 2022 Chevy 2500HD showing a warning message that our 5th wheel was not connected and then it was connected. So we replaced the plug connector with this. This was not the problem. It was loose wiring in the electric box. Rewrapped all the wires and works perfect now. We do like the metal connector though. It’s stronger and feels more secure than the hard rubber one.

These are really great quality. I always go to E Trailer first.

Very happy with it. Has held up well and works as I would expect it.

by: Ed 03/21/2022

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.

by: Eric 08/20/2025 One Year Later

Very well made. Has Held up well. Seems to be much better that the plastic alternatives

Holding up well. I use it every other weekend.

by: mountainman716 09/30/2016 One Year Later

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.

by: Michael 08/03/2024

By appearance it is a quality replacement plug for the trailer end plug, I would give it 5 stars except that it has a single set screw to hold the piece that has the electric contacts into the outer shell when tightened causes the center section to tilt, to prevent this the fit between the two parts needs to be a snug fit not the very loose tolerances it has.

by: Steve 04/10/2023

Great plug. I'm going all metal with my installations on trucks and trailers. The strain relief is especially effective to prevent cable from pulling on screw connections. Brakes are important.

I AM GRADUALLY REPLACING ALL THE PLASTIC WORTHLESS TRAILER PLUGS WITH THESE GUYS !ALSO EXCELLENT PRODUCTS

by: Michael 08/28/2023

I had one of these on boat trailer. Slides in so nice with a click, unlike plastic ones that swell and go in kinda wonky. Swapped both other trailers to this style, well worth it.

by: Lyn A. 01/19/2011

The 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.

by: ChuckW 04/14/2011

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.

by: Jay 06/27/2014

Both male and female connectors are good quality!

by: Ken 04/07/2023

Got tired of always having to replace the plastic plugs on the trailer that sets more than it gets used and the sun makes the plastic ones brittle so I went to the metal you guys had a good price and quick delivery thanks

by: Don C 07/08/2015

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

by: Hernan 05/11/2011

well; fast shipping.

by: Paul Schroeder 06/27/2017

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

Thanks

by: Tony 04/06/2025

I been looking for a metal plug-in for a while. Seems like the plastic ones get brittle and brake over time. Seems to be made of good quality.

Toughest 7-Way Trailer Wiring Connector
We offer a metal trailer 7-way with the part # HM48510 which would be the toughest 7-way out there.

Does Pollak Metal 7-Pole Have Latch that Lid Holds it Into Socket
Hey Don, unlike the plastic 7-way plugs the Pollak part # PK12702 does not have a raised edge that the lid of the 7-way socket would be able to grab onto. So it's doesn't have a latch built into it that prevents it from staying in but generally these fit tight enough that it's not an issue.

Is The Pollak Metal 7-Pole, RV-Style Trailer Connector # PK12702 RV Standard or Traditional?
The back of the Pollak Metal 7-Pole, RV-Style Trailer Connector # PK12702 can be wired to either the traditional or RV standard wiring depending on what colors your trailer wiring uses. As you can see in the image all the functions are in the same location and the only difference is the colors of the wiring being used. As an example the 7-Way Wire # DW04914-1 we sell by the foot uses the RV standard wiring colors so it would follow that diagram. While many of the colors are used on both...

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...

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...

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...

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....

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...

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.

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...
