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.

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

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

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

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

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

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

The # A7WCB, 7-Way trailer side connector has a wire clamping mechanism that just has a clamp that wedges the wire into the connector to keep the wires from being pulled out, there is nothing at the back of the connector to prevent moisture from entering the connector. Another difference is that this connector has...

  • Installing a 7-Way Trailer Connector and Brake Controller on a 2006 Ford Expedition
  • On your 2006 Ford Expedition, there should already be a factory installed trailer connector. It will either be a 4-Way flat or a 7-Way blade. If your vehicle has a 4-Way flat, you will need to add Adapter 4 Pole to 7 Pole and 4 Pole, # 37185. On this connector, you would plug your 4-Way into the corresponding plug on the adapter.

If you look up part # H20046, you will see about 1/3 of the way down the page a chart that will give you a wiring guide. It gives you the color of the wire and how it relates...

  • Are Trailer Coupler Mounting Holes The Same And Is A Brake Controller Needed For Electric Brakes
  • The standard, basic straight tongue coupler I have that will fit a 3 inch channel, and a 2 inch ball with a 6,000 lbs. weight capacity is the Fulton Fast-Lok Coupler with Cast Ball Clamp, 2 Inch Ball, 3 Inch Channel - 6,000 lbs, part # F346000301.
