This product solved a chronic error message displayed on my 2017 Chevy Tahoe when connected with other brand trailer connectors. Positive fit and well made product.

About 4K towing it continues to function flawlessly

The quality is good with and I am happy with that. Just do not follow the wiring labels on it. Half the listed colors are incorrect. I made the mistake and had to rewire after going to etrailer website instructions and getting the correct wire locations. Works good now though. Other than that very happy with it.

The colors on this plug are for RV Industry Standard wiring. Traditional Wiring colors are different. That said, the individual terminals are in the same order as far as which terminal goes to tail lights, which terminal goes to right turn signal, etc., regardless of which wiring colors are on your existing harness. Now if only the person who converted the wiring on my sisters horse trailer to 6 blade 7 terminal had followed the color codes of either..... That however, will be corrected this Friday!!!!

Thanks for the info, and this is exactly why we recommend using a good circuit testers and testing all the wires for the function. Then connect according to the function of the wiring, not by color.

I had an non-standard use for this connector. I neds a quick disconnect for 6 LED lights on the roof of my truck. This did the trick wonderfully but it is probably way overkill for that purpose.

Your wasting your time looking for a better company to do biz with, etrailer has it all under one roof, quality merchandise, bend over backward staff going the extra mile, bodacious customer service and Im sure I left something out here, trust me, try etrailer youll be blown away. They are setting the example in the industry.



by:

The item ordered was exactly what what advertised and the shipping was very rapid I'm very happy with everything.



by:

Product so far has worked great for a pinched/cut OEM 7pin cord. It isnt weatherproof like an OEM connector to the cord-as well as the female end of the connector but then its just the connector so totally sealed is not the design for this. It works fine & currently has saved me from having to purchase a connector & wire cord as 1 piece & some shennagins with installing that set up.

Product is working fine after a year of use of several connectsdisconnects every month. Connections are solid. No failures to pass powersignals. Very satisfied!



by:

Easy install, water tight connection to trailer cable.



by:

Product works as it should. However, etrailer shipping method is very poor using USPS ADVANTAGE SHIPPING. Part ordered in Wentzville Mo., and I live in Salem Mo. Using the cheapest shipping method, they can get. It traveled to Philadelphia, Pa. then started it route back to Missouri. Should possible use a better quality shipping service since customer pays for shipping.

Connector was exactly as advertised, arrived promptly, and worked perfectly.

GREAT PRICE



by:

I got exactly what I was looking for and there were no deficiencies in the product quality. The following comment does not apply to eTrailer; it's just something I want to say. I purchased the connector because I was chasing an intermittent problem associated with the Chev braking software and the Hydrastar braking unit in my Montana 5th wheel. After several attempted fixes, I finally solved the problem by purchasing a diode from Hydrastar.



by:

I searched for this part and level of quality all over the internet. When I found this at etrailer, I had to double check the price as it was about half the price of others that I had found!



by:

It served its purpose to convert 4 connection to 7 connection to make it compatible with Toyota 7 connection set up diagram which is different than many American or other 7 point connection. Thank you E-Trailer . 5 stars and it's working just fine 1 year out from installing.



by:

Installed easily and working okay.



by:

Sooo, bought another one to match my truck side connection as GM uses Pollak, which are known to not play well with other brands. The design is just a wire clamp to wire it, which I did with the first one, but trying to get it secured I stripped out the screw. There are no torque specs provided. I’ll move to crimped ring terminals on this one and dial back the torque a bit.

Still working just fine, solved the issue of brand consistency with GM truck, and still recommend using ring terminals should have noted you will need two sizes and angles



by:

Using this product to replace inputs from a straight-4 hookup plus add'l wires from a supplemental light system for my truck. Works exactly as advertised; saves me a lot of hassle. Installer must have some rudimentary electrical-connection knowledge.

You must also know which of the seven contacts does what for your vehicle to install this correctly; should be in your car/truck's manual.

Four instead of 5 stars just because the entrance/exit hole for wires needs supplementation to make it water-tight.

Product is easily worth the money and functions exactly as one would expect.



by:

I have this same plug (PK 12706) on the Boat Trailer and it works perfect, and never disconnects or shorts. Now I'm putting this same plug on the Snowmobile Trailer. I'll let you know if I have any problems. Anything to do with trailer issues I always contact eTrailer Company first.
Thanks,
Ron

I'd did get here , but it was sent in my wife's name that is why I didn't get it from the mail on 3/9/26 but I remembered an email I received with my order but in my wife's name, I really don't understand why my wife's name was on anything, she didn't order it

Hard to find trailer plug with brass contacts. Speedy shipping, good price

Dee Dee was the consummate professional when I spoke with her concerning my order. She is very knowledgeable and was very helpful. Dee Dee is an asset to etrailer.

product was very easy to assemble with the instructions from the e-trailer site. This is the perfect replacement for my 7-pole plug that wore out after 15 years of usage.

  • How To Plug 1997 Lance Truck Camper Into 7-way Connector On 2016 Ford F-250
    We have run into this quite a few times in the past, and the best option will be replacing the Lance 7-pin connector with a standard 7-way blade connector like the # PK12706. This will give you a standard 7-way connector to plug into the factory 7-way on your 2016 Ford F-250. There is not a adapter compatible with the connector on your 1997 Lance Camper as they use their own style connector that does not match any standard connectors. I included a video of the # PK12706 for you to take...

    The Demco Hydraulic Trailer Brake Actuator part # DM72VR should be a direct replacement for the Atwood 61101 Brake Actuator that you have now. This newest updated it rated at 7K instead of 6K. This is a bolt on option that mounts on 3" centers. The review you are referring to, the customer did indeed weld the brake actuator to his tongue but this is not required for installation because it is a bolt-on actuator.

  • How To Power Third Brake Light On Camper Shell Using 7-Way Trailer Connector
    Yes, you can use the factory trailer connector on your 2015 Nissan Titan to power the third brake light on your Leer camper shell. That said, they don't make a plug and play harness for this so you will need to do some wiring but no splicing into the vehicle will be required. Basically, all you need is the Pacer Performance 3rd Brake Light Logic Module part # PP20-702, the Pollak Black Plastic RV-Style Trailer Connector part # PK12706 and then some loose wire and connectors to attach it...

If you typical pull a trailer that has a 7-Way connector then you want to follow the pin out diagrams I mentioned. If the chippers that you tow have a different configuration then the Hopkins Adapter # HM47535 will likely do the trick because you can change it so that the center pin is either related to the electric brakes or the 12V power.

    The easiest way to go from a 7-way round connector to a 7-way flat would be to get a Trailer Connector Adapter part # HM47425. However, if you are looking for a more permanent solution you would need to remove your 7-way round connector and wire up the trailer wiring to a 7-way flat connector like part # PK12706. In order to do that check out the different diagrams I attached that will help you wire up the new connector. The wiring could be different so you may need to verify the functions...

  • How to Power Trailer Dome Light When Not Connected to Tow Vehicle
    The only way you could power interior dome lights on a trailer without it being connected to a tow vehicle would be to power the lights with a battery like a breakaway battery. How you choose to wire up the batteries will in the end be up to you, but since breakaway batteries need to be charged up when you are towing I would be careful not to drain the battery with the dome light.

  • Would 7-Way Trailer Wiring Circuit Have Amperage Rating for Powering 13 amp Horn
    Standard trailer wiring circuits on 7-ways like the part # C58155 and # PK12706 are rated for up to 40 amps so if you wanted to use a 7-way like this to power a horn that is rated for 13 amps you certainly could.

    Electric tongue jacks like the Electric Jack w/ Footplate - A-Frame - 25-1/8" Lift - 3.5K - Black # EJ-3520-BBX are designed to use a 12v power so if you want constant power I recommend using a trailer battery for connection. If you only want power when connected to your vehicle 7-way, you can use the Pollak Black Plastic, 7-Pole, RV-Style Trailer Connector - Trailer End # PK12706 to connect to the 12v Pin.

    When wiring a 7-Way on your trailer with 5 wires, your green wire will be right turn/brake, the yellow wire will be left turn/brake, the brown wire will be the taillights, and the white wire will be the ground. You will want to find out if the blue wire on your trailer is needed for 12-volt power for trailer accessories, for electric brakes, or for a reverse brake lockout, if your trailer has surge/hydraulic brakes. Looking at the rear of the 7-Way connector, if you need the blue wire...

  • 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.

The minimum wire gauge for the remaining Green (right turn/brake) wire, the Yellow (left turn/brake) wire, the Brown (tail lights) wire, and the Purple (reverse light) wire is 16 gauge.

    I did some checking and it looks like the front wheel drive versions of the 2017 Ford Escape can be towed on a tow dolly. The 4WD versions cannot though. The Roadmaster Tow Dolly part # RM-2050-1 would be a great option for a tow dolly. It's our best priced option and would work well. To use the dolly's brakes though you'll need to install a 7-way in place of the connector that's on it with the part # PK12706.

  • Recommended Tow Dolly for 2007 Toyota Prius behind 2017 Toyota Sienna
    The tongue weight of a tow dolly is minimal because it has the weight of the front of the tow vehicle across the axle. So you will have almost no tongue weight when using the Roadmaster Tow Dolly with Electric Brakes # RM-2050-1. You will simply need to account for the towing weight of the 545 lb # RM-2050-1 along with the 2,932 lbs curb weight of your 2007 Toyota Prius. Your 2017 Toyota Sienna has a towing capacity of 3,500 lbs, so you can use the # RM-2050-1 and be just under your...
