Video Transcript for Pollak Wiring PK12706 Review

Today we'll be reviewing part number PK12706. This is the Pollack Black Plastic 7-Pole RV Style Trailer Connector. This is a standard 7-pole plug. It's going to connect your trailer to your socket on your tow vehicle. Made from a black plastic construction, so it's going to eliminate rusting. It's also going to enhance the appearance.

The interior design is made from a non-corroding, shock resistant system. The terminals are reinforced, so it's going to eliminate shorting out. The center pin will accept up to 8-gauge wiring. Here on the rear we have the vinyl insert. That's just going to help keep out dirt and moisture. It's also going to feature that dual grip system, so it's going to be very easy to remove the plug from the socket.

It's also going to ensure that the connector is plugged into the socket using the safety latch system which is just this little raised portion here on top. This is going to be color coded, so you have RVI Standards. To gain access to the connectors, you just loosen up this set screw here on top. It's going to bring this interior piece out, run your wires through here, all the way through the casing, connect them with this portion pulled out, reinsert this, and then reset or tighten back up the set screw here on top. That's going to do it for part number PK12706. This is the Pollack Black Plastic 7-Pole RV Style Trailer Connector.

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. 137963


Comments

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.

Seems to be a well made product that should make it easily replaceable for me. The usual excellent delivery and service from etrailer that I have come to expect. 143321


Comments

It works very well. I am going to have to replace the wiring itself soon, as I dragged the wiring harness on a bad hookup. MY FAULT, not the connector.

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. 449544

The plug appears well made, was competitively priced, shipping charges were reasonable and it arrived quickly!! Additionally to help with trailer wiring installations and repairs ETrailer has very nice trailer wiring diagrams for the various harnesses out there (4, 5, 6 and 7 pole/pin/blade connectors etc). The diagrams are a great resource & I refer to them frequently and had "assumed" they are the accepted standards for the industry. The plug pins on this product are marked with a number and a color. While the numbers correspond to the ETrailers diagram the colors do not. Not a big deal but one needs to pay a little more attention during the install. 227939

I am glad I came upon this site. The staff is friendly courteous and helpful. Since I live in Canada it is a big problem if I had to send items back across the border to etrailer if the items were not what I thought they were. The short videos that etrailer provides with each product is extremely helpful in determining to purchase or not. Thank you for that feature. Knowing a little about video production and the costs associated with that, it must cost etrailer a pile to give us (the consumers) what appears to be a simple addition on their site Thanks again guys/gals 396627

Got my new/used trailer rewired and my '16 Silverado started throwing "check trailer wiring" code ! Trough much research and googling the code I found the factory used the POLLAK 7 pin receptacles . And some 7 pin plug makers were not up to OEM standards . They fit sloppy . So until my new end came I wrapped the sloppy end with electric tape for a snug fit bent tabs out slightly and greased with dielectric grease . That stopped code . When the new end arrived I changed it and seams the problem is solved . 312561

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 236504

The product was fine. Shopping experience was good. Unfortunately it didn't fix my problem. But it has nothing to do with this company. It's my trailer. 503633


Comments

The package came as expected and my shopping experience was great. However, my old trailer has had some wiring replaced, and the colors dont match up. We only have 4 wires in the 7 way plug. We tried changing to a 4 way, but its not working either. Frustrated, but not etrailers fault. I thought this was going to be quick and easy.

-- comment by: Amy - 05/03/2018

Since wiring colors can vary, we recommend wiring by function, not by color. The quickest way to determine which wire on your trailer harness controls which feature is to use a 12-volt battery grounded to the trailer frame. Then apply 12-volt power to each unknown circuit. Ill link you to a technical help article that explains how the 7-way should be wired by function.

by:


The item purchased more than surpassed the requirements, it will defiantly out do the original plug, the only thing that I did different was to coat the internal wires with some liquid electrical tape to protect against shorts and the same on the side the cable goes through, I encourage everyone to look at their old 7 pin plugs for wear, mine was defiantly in need of replacement, just make sure to use the PK12706 because it seals up better, great job erailer 15100

The color printed on the post didn't line up. wired it up like plug showed and didn't work. I went ahead and did it one by one with a meter and know it works can only give this one stars. My truck has been hauling 5th wheels and travel trailers and varies other trailers with NO problems what so ever so I know it wasn't my truck. All in All the product did work maybe I got just got the bad one won't stop me from buying from etrailer 511743


Comments

There are a couple different color codes for trailer wiring, so its recommended that a trailer connector be wired by function, not wire color. Ill link to a help article that shows the two most common color codes.

My only complaint with this product would be that the wiring on my trailer did not match the color coding that is listed on the inside of the adapter (where the wires attach). In fairness, I removed a 4-point adapter and wired up this 7 point to the trailer. A little Google searching for what the different pins do matched it up with what the adapter was looking for and I had it working. 187270



- PK12706

by:


Color coding on the screw terminals was incorrect. I needed to match up to my trailer diagram for proper connections. Housing is a little mishapen so small gaps, though I don't think this will be an issue. Multiple set screws or a more rigid housing would probably solve this issue. Cable retaining clamp is very sturdy. Only question is longetivity but at the price I can manage. 208304



- PK12706

by:


Purchased to replace the existing trailer connector. This item doesn't seem very sturdy though. The set screw on the plug end is very small and doesn't seat properly into the base, making it possible for the connector piece to possibly remain in the vehicle female plug end. I'm holding off on installing in case I can find a better/sturdier replacement. Shipping was quite fast. 72444



- PK12706

by:


Well-designed. The blade setup makes it much easier to use ring terminals (just bend the end of each brass blade and take off the washer), giving complete confidence that wires won't become disconnected even if they get yanked a bit. Nice seal at the rear. Can be a bit difficult to slide the housing over the cable, but add some grease and it should work like a charm. 58964

I'd like to express my appreciation to etrailers, I had an issue with my connector due to the fact that it drug for 13 miles at speeds of 55 miles per hour. They not only had the part I needed but made sure I received it promptly so I wouldn't be without trailer lights for more than 24 hours. I highly recommend them and I have found my new trailer part supplier. 175317

My truck, 2008 Dodge Ram 1500 didn't have factory harness for 7 way trailer connector. My wife bought me a camping trailer with brakes. I did my research on etrailer.com and ordered all parts I though I would need. The videos and instructions made it a simple process. Installed everything in about 3.5 hours and everything worked great. Thanks! 407194

This product was recommended by my GMC dealership for a better connection between vehicle and trailer. I was having many trailer wiring disconnected alarms, which led to my Truck being serviced to find the fault. The Pollak product is very different from the original trailer connection. This appears to be a problem with the newer GMC trucks. 504498

Replaced this exact connector after years of it being abused and dragged endless miles behind the truck after being ripped out accidently.

I was having a problem with the right turn signal on my trailer. After several hours of tracing wire and power I found the plug from trailer to vehicle was bad.

Product is well made, easy to disassemble. When making up wire connections it's better to use ring lugs as shown in the video. Would have preferred terminals that accepted wire conductors directly but this isn't that big of an issue. Overall well satisfied with connector. 17804



- PK12706

by:


Great price, good product. The only thing I noticed about this connector is the fact that the colors are labeled next to the terminals and two of the colors don't match schematics. I hooked mine up according to the schematic available at e-trailer and it works correctly. 13053

Hi there actually I had to go out and buy another whip end because when I hooked it up based on the color diagram and I put my blinkers on they didn't work properly or connections were made really good I did them twice just couldn't figure out why wouldn't work properly 439218



- PK12706

by:


Great item, just remember that GM typically does not tie down the 12V for the trailer connectors. In late model trucks its coiled and taped under the master cylinder. It ties to the 40 amp lug on the front of the main fuse box on the drivers side engine compartment. 248147



- PK12706

by:


The product appears to be well made and is easy to use but the terminal for the "right turn" wire is labeled with the incorrect color. Do not rely on the color coding on the connector but rely upon a wiring diagram for the correct location in connecting wires. 43653

This product is a good replacement, the only consideration is that there is only one set screw that holds the insert to the body, to make it sit flush and secure, i had to pull the wires tight. I think the next one I buy will be all metal type. 203280

On most trailers, the lights ground through the mounting studs. Make sure that at each ground location, there is no dirt or corrosion. A bad ground connection is one of the leading causes of lighting malfunctions. You can also probe the wires...

  • Camper Lights Do Not Work When New 7-Way Connector on Camper is Plugged Into Vehicle
  • Sounds like you have eliminated your truck as being the problem. With your truck plugged into the trailer you will want to use a circuit tester, like the Quickee Tester, part # 3808, and check each terminal on the new 7-Way connector on your trailer to make sure they are working properly. Looking at the front of the 7-Way trailer connector, make sure the number 1 terminal (ground), at the 5 oclock position on the connector, is grounded properly to the trailer. Also, make sure to test...

  • Recommendations For 7-Way to 5-Way Trailer Wire Adapters
  • You can install a 7-way trailer plug on the trailer and only wire the 5 circuits you need based on our FAQ page on wiring, which I have provided a link to. If you go this route, you will need to trace each circuit on the trailer to determine its function and then wire it to the plug accordingly. I have provided a graphic showing the function of each individual circuit on the 7-way trailer plug. You also might need a new adapter to connect your 7-way plug on your vehicle to the 5-way...

  • Instructions for Completely Rewiring a 14 Foot Tandem Axle Dump Trailer
  • Rewiring your 14 foot dump trailer is pretty straight forward. I would start with a 20 ft. Wishbone 4-Way Trailer Wiring Harness, # A20WB, to provide wiring for the stop turn and tail lights on your trailer. We have a video detailing how to install this type of harness for you to review, see link. Next, I would use the RV-Style Trailer Connector, # PK12706, and remove the 4-Way connector from the 4-Way harness and install the wires in the proper locations in the 7-Way connector. Our...

  • Complete Wiring for Lights, Electric Brakes and Controller for a 94 GMC 1/2 Ton Truck and Trailer
  • Lets start with your 1994 GMC 1/2 Ton Truck. You will need to start with the # 118315 4-Way connector. Once the 4-Way is installed, see instructions link, you will need the Brake Controller Installation Kit, # ETBC7, and a brake controller. I recommend the P3 Brake Controller, # 90195, which is one of the best controllers we carry. We have detailed instructions for installation of the controller and the wiring kit, see links, and we have installtion videos of a brake controller and wiring...

  • Parts Needed for Installation of Electric Brakes on a Coleman Pop-Up Camper With 8 Inch Wheels
  • The 8 inch diameter wheel on your Coleman Fleetwood pop-up camper is not large enough to accept an electric brake hub and drum assembly. Seven inch brake assemblies like # 23-48 that you selected work with the Trailer Hub & Drum Assembly, item # 8-257-5UC3, which will fit in wheels starting at 10 inches in diameter. You would need to upgrade your wheels and tires to either a 5.30-12 load range c wheel and tire combination, or a 205/65-10 load range c wheel and tire to meet the capacity...

  • How To Wire Separate Turn Signals And Backup Lights On A Trailer With a 4-Flat Connector
  • To wire your trailer for separate turn signals you will need to use the Pollak 7-Pole Trailer Connector, part # PK12706, and the Tow Ready Vehicle to Vehicle Taillight Converter, part # 118158. You will replace the 4-flat on your trailer with the Pollak 7-Way connector. The wiring on your 2005 Chevrolet Tahoe with the 7-way connector will stay as the factory wiring. It will not need to be changed. I am including a picture of the 7-way trailer connector that will show the function...

  • How to Adapt a 7-Way Round Connector to a 7-Way Flat
  • The easiest way to go from a 7-way round connector to a 7-way flat would be to get a Pollak Trailer Connector Adapter part # PK12-724. 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...
