Video Transcript for Pollak Wiring - Trailer Connectors - PK11-934 Review

Today we're going to be taking a look at Part Number PK11-934. This is the Pollak wiring harness extension. It's going to feature the seven-way RV style connector. You can extend your factory harness to a new location or add a different style connector without having to remove your factory harness. This is a three foot extension, so it's going to extend your vehicle's seven-way RV style connector. One end of the wiring harness is going to plug into the back of your existing seven-way. That's going to be this portion here with the plug.

The other end has the exposed wires. That way it can hard wire into a new connector. If you need a new connector, you can find those right here at We offer quite the variety when it comes to different style connectors. It's going to feature a protective wire loom that goes around the wires. This is going to keep them safe and away from damage.

This system is designed for vehicles with factory seven-way connectors. Again, the length of the extension is going to measure three feet long. Just a reminder that before installing a new connector, you always want to test the wires for appropriate circuits to make sure that you're making the correct connections. That's going to do it for a review of Part Number PK11-934. This is the Pollak wiring harness extension seven-way RV style connector. .

Pollak Wiring Harness Extension - 7-Way RV - 3' Long - PK11-934

Average Customer Rating:  4.3 out of 5 stars   (7 Customer Reviews)

Extend your factory harness to a new location or add a different style connector without having to remove your factory harness with this handy 3' extension.


I would recommend shopping for a different product than this one. There are fairly standard color codes for the wiring to make it easy to hook up with the trailer. Only one of the seven wires was in the correct position, and it was the yellow center wire that is not normally used. The white wire that is normally used for a ground wire is heavier duty than the others, but it was not connected where the ground wire connects to the tow vehicle. Even worse, the connector to the tow vehicle uses very flimsy metal pins, and they did not make electrical contact with the plug on a Ford F-150 truck. I even tried bending them to make contact, but to no avail! Avoid this item.

I will have Customer Service contact you.


I needed this unit to convert the connection on my Dodge Durango to the European trailer connection. Connected through a junction box worked OK.
I was surprised that a standard unit for this conversion was not available.


My son is very happy with his trailer wiring plug, in fact it came today and he has already installed it. Thank you so much.


Perfect. Thanks! You folks are awesom e.


Good quality product. I gave only 4 stars because I cannot indicate a complete addresse in your website. You have only one line available.


Was exactly what the picture. Thanks al ot

  • How to Reconnect Wires From Pollak Wiring Harness Extension # PK11-934
    It sounds like the brown and green wires have been pulled out from the plug-in harness on your Pollak Wiring Harness Extension # PK11-934. To reconnect the wires, you will just need to make sure they are connected to the appropriate pins on the plug. When looking at the back of the plug end on the harness, the brown wire should connect to the open port in the 9 o'clock position and the green wire will connect at the 1 o'clock position. I have attached an image that you can also use for...

  • Can Pollak Wiring Harness Extension be Used for Replacement OEM Wiring on 2015 Chevy Silverado 1500
    Yes, the Pollak Wiring Harness Extension # PK11-934 is exactly what you'll need to replace that wiring connection. The round plug on the back is called a US Car Connector and is a universal plug that fits at the back of the vast majority of 7-Way sockets like what you have on your 2018 Chevy Silverado 1500.

  • Do You Sell Just a 7-Pin RV-Style Plug from the # PK11-934?
    While we don't have just the plug from the # PK11-934 individually, the best option is to purchase the # PK11-934 and just disconnect the 3-foot pigtail that comes with it to use the connector.

  • Replacement 7-Way Trailer Wiring Harness for 2011 Chevy Silverado 2500HD
    If you are referring to the actual wiring then you will want to use Pollak Wiring Harness part # PK11-934. This harness will require you to cut and splice but it would be the only option we have for you as we do not carry OEM parts. However, if you are referring to just the connector then you can use the Twist-in 7-Pole, RV-Style Trailer Connector part # PK11916 which install in the same position and way as the factory 7-way trailer connector on your 2011 Chevrolet Silverado 2500HD.

  • Replacement 7-Way and Pigtail for 2002 GMC Sierra
    So while I can't see your cart, I believe I get the gist of what you're trying to do in replacing the 7-way and pigtail of your 2002 GMC Sierra. What you can do is add a new twist-lock plug, like you mentioned, as well as a compatible 7-way pigtail to splice into your factory wiring (if that's what you were saying - please let me know if that's incorrect). What you would need in order to do this is the following: - Twist-in, 7-Pole, RV-Style Trailer Connector for Chevy and GMC Vehicles...

  • Best Way to Connect Truck Camper 6-Way Pin to Truck 7-Way Connector
    It sounds like you have a Lance truck bed camper. Lance came out with their own specialized 6-Pin which can be frustrating as it doesn't match with any standard connectors and there aren't any adapters so we typically recommend just replacing it with a standard 7-Way like the Hopkins # H20043. This way the camper wiring matches easier with other connectors. All you have to do is cut off the Lance connector and match the functions on the 7-Way and you'll be good to go! I'm attaching an...

  • Availability of 3 Foot Wiring Harness with USCAR Male and Female Ends
    In order to get the two ends on your wiring harness, you will have to wire the # PK11998 and # PK11-934 together. This is the only option available that will do what you have described. Unfortunately, this is not ideal given the fact that you would like to order a large quantity. If your goal is to move a 7-way from the bumper to the bed I do have a different solution. I recommend using the # C56070 Curt 5th Wheel/Gooseneck Custom Wiring Harness w/ 7-Pole Connector. It is longer at 7...

  • How to Install a 7-Way on a 2007 Chrysler Aspen
    Since your 2007 Chrysler Aspen does not have trailer wiring currently you are going to need to first start with a 4-way. For that you would want the part # 118390. This is a plug and play option designed to fit your vehicle. Check out the install video for more info. Now if your trailer does not have brakes all you would need is the part # 37185 as an adapter to convert the 4-way to a 7-way. If you do have trailer brakes you would need the # ETBC7 instead of the # 37185 and a brake controller....

  • How to Make the 7-Way Harness part # PK11-934 Longer
    The only solution we have for an extended version of the part # PK11-934 is to get the part # DW04914-1 which is jacketed 7-way wiring sold by the foot so that you can make the harness as long as you need it to be. For butt connectors to make the connection you would want the part # DW05744-10.

  • Ford OEM Connector With Bare Trailer Wiring For 2001 F-350 Dually For Custom Install
    For your 2001 Ford F-350 Dually, we don't have a bare wire kit with the gray OEM harness. I recommend using the 7-way # 20031 that is confirmed to fit and cutting the CAR adapter off the other end. This will give you the relays and fuses you need to make those wires function correctly as well. For a shorter length you can use # 118243. If you just need a 7 way connector, you can use # PK12-707E and connect the wires. If you need a wiring extension you can use # PK11-934. If you just...

  • Recommendation to Extend Factory 7-Way to Fit with New Bumper on 2010 Ram 2500
    There are a couple of options to extend the factory wiring at the rear of your 2010 Ram 2500 so that it can reach the new connecter opening on the 2015 bumper. The easiest solution is to use a 5th Wheel Wiring Harness like the Curt # C56070. This will plug in-line with your existing factory wiring and provide an extended harness on the other end. The only drawback on this option is that the Curt # C56070 represents the shortest 5th Wheel Harness that we offer at 7 feet long. So you will...

  • Is the Harness Included with the Hopkins Trailer Connecotr HM47180 Available Separately
    It sounds like you are looking for the wiring harness portion of the Hopkins Endurance Multi-Tow 4-Way Flat to 7-Way RV Trailer Adapter part # HM47180. If that is the case then this part is not available separately but you can obtain something similar with the Pollak Wiring Harness Extension part # PK11-934 and the Quick Fix 4 Pole Flat Trailer End part # HMC20031. If you need butt connectors to finish up your connections you can use part # DW05745-5.

You could also go all out and wire it yourself using the 7-Way Molded Trailer Wire Connector - 3' Long # H20042 and splice it to your current connection cable with the Butt Connector - PVC - for 16-14g Wire # DW05714 and 12-10 Gauge Butt Connector # 05732-2.

  • Is there a 7-Way Extension that is 12 to 18 Inches Long
    It will require a little hardwiring but you can use extension # PK11-934. One end plugs into the back of a standard US car connector 7-Way. The other end has blunt cut wires that will need to be spliced into the existing harness you have. Another option would be to cut the wiring harness somewhere and splice in additional wires using # DW04914-1 which is sold by the foot. I recommend 2 feet in case you need some slack so you would enter 2 in the quantity box. I recommend using heat shrink...
