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.
Average Customer Rating: 4.6 out of 5 stars (143 Customer Reviews)This standard, RV-style, 7-pole connector provides a secure connection between your trailer and tow vehicle. Black plastic construction prevents rusting, enhances appearance and makes plug removal a snap.

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
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
I have just received this, it appears to be a fine unit, nice brass wire lugs and screws, an acceptably strong plastic body with a nice, tight wire retaining clamp - highly recommended! 126771

Perfect. Exactly what I needed 96903

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 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

VERY EAZY TO WORK WITH-- ABOUT 10 MIN. OR LESS , NEW PLUG ON AND WORKING. 305288
by: Deny R.05/23/2011
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

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
by: Dana H.06/30/2015
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
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
by: Russell F.11/07/2012
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
by: Steve V.09/25/2013
Replaced this exact connector after years of it being abused and dragged endless miles behind the truck after being ripped out accidently. The new connector was very affordable and fits very snugly in the truck so i know it is not coming out. very personable emails from the etrailer folks to let me know it had shipped 101426
by: David LH05/22/2016
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. E trailer had the right part at the right price. it took less the 30 minuets to install the new part and it is still working fine 1 year latter. 251101
Excellent quality product and etrailer provides wiring diagram. Arrived quickly in perfect condition. Great price including shipping. 67837
by: Jim B.06/23/2011
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
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
by: David C05/02/2016
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
by: William M. Huffman06/11/2012
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
by: Frank A.10/30/2012
I could not believe how easy it was to install the products that I purchased from you. The quality of the products are better than almost everything else that I saw on the market and the price was right too. Thanks for being so prompt on the delivery. 58419
I installed these products over the weekend. These products fit perfect. Fast shipping. This is my first time I bought from here. Can't say enough. Great people to deal with! Made my job so easy. Thank you so much. Best prices and quality out there. 72232
by: Richard T06/14/2015
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
by: Dana A12/07/2011
got this to convert my trailer to 7 pin to match my 2011 Silverado, didnt have to use a 7 to 4 pin adapter using this. Etrailer has a video showing what wires to hook where to use as a 4 pin replacement, couldnt be easier 27883
by: Jeff Pittman10/16/2014
Called and spoke with Christy B, she added this connector to my order, exactly what I needed, haven't connected it yet since I'm not using my trailer right now. Will call her again real soon for another order. 156403
by: Chuck S03/17/2014
Awesome concept, but poor quality, the connector pulls apart when taking off and does not easily attach since the lower part of the connector is "flexy" ... need to try some super glue to see it it works better 120949
It is what it is so not much to write about. Quality and fit is great but YOU HAD BETTER PAY ATTENTION to the WIRING diagram. It is not color for color etc but they do warn you of this. Just some helpful info. 37768
Like the female socket, it seems to be well made but twice the price I could have purchased elsewhere. I bought this because something I read caused me to believe is was made in the USA. It's made in Taiwan. 99211
Nice connector for the price. Had no issues wiring it and seems like it will hold up for a while. i did have to adjust the pins in the connector a bit to get it to go into my truck plug but no big deal. 268554
Product quality was pretty good. Plastic housing was flexible and distorted if the small set screw over overtightened. Terminals were easy to use and accepted bare wire or crimped fork connectors. 123027
The product arrived on the date promised. Was the right part and is installed and works perfectly. Courteous service and timely delivery.....And at a great price. Thanks again 67090
by: Ray C04/27/2014
I bought from etrailer before and had excellent service, this purchase was no different, great service and the Pollak brand connector was the same brand installed on my Mercedes from the factory. 127598
by: no name03/13/2013
Very easy to install. The color indicators on the part don't match the actual wiring, but just note down your current configuration prior to installation, and it's very easy. 70496
Just what the trailer ordered! Good sturdy plug and even stood up to me forgetting to unplug it when I pulled out from under my horse trailer (long day ropin'). Thanks! 14376
by: Bobby B10/04/2016
These guys are great. Fast, simple and on time. Wasn't a big part but essential. I received the same treatment as though I'd spent a bunch of money. Great team. 303249
Easy to install and worked perfectly to replace the corroded socket on a my trailer. Much easier than trying to clean up the connectors, and possibly cheaper. 185544
by: Guitar Photographer04/04/2012
Not as sturdy as I had hoped but it looks very servicable. Note that the colors stamped in the plastic do not conform to industry standard wiring practices. 36186
by: C. Williams03/01/2012
Quality of this connector on par with anything available at a great price. Good product and service with a 3 day delivery from time of order. Good vendor! 32959
by: Connor M.10/24/2014
Using this to tap into the auxiliary wire for additional reverse lights. makes it easy to disconnect and I won't have to splice any wires on my truck. 157757
Nice plug for occasional use but I do not think it would stand up to daily use. Needs a second screw to hold it together better. 149091
by: bob r10/26/2013
The camper hook plug worked really well. each terminal had which colored wire hooked to it . This made it very easy tohook up. 105309
by: John H.04/13/2016
This purchase was for a replacement plug for a gooseneck trailer. It works very well and seems like a durable part. 244046
by: Gus S.09/24/2015
I just installed this replacement hitch plug, and it was very easy. Good quality, and I'm happy with my purchase. 227409
by: Bobby S.04/03/2014
I just wish they made these that could be drug down the road 500miles and plugged right back in with no rewiring. 123650
by: charlie johnson08/26/2013
i liked this. Oh.I am making testers so i ordered a variety of these types of parts. i expect to order more soon. 96991
