When you need more than the basic trailer lighting, this 9-pole socket steps up. The Pollak 9-Pole, Round Pin Trailer Socket – Vehicle End gives you dedicated circuits for brakes, charging, running lights, backup power, and more. With nine pins to work with, it’s ready for setups that use auxiliary power or even refrigeration units.
Every circuit has a recommended wire gauge so you can match it to your trailer’s electrical load. Use 8-gauge for ground and battery charge, 12-gauge for brakes and auxiliary circuits, and 14-gauge for lighting, signals, or reefer power. That layout makes wiring simple and reliable whether you’re setting up electric brakes or powering extra lights.
This socket is designed to work with the Pollak 9-Pole Trailer Connector # PK12906 on the trailer side. Together they create a solid connection that handles multi-circuit towing jobs without the guesswork. You wire each pin by function so both ends match exactly.
For a clean install at the back of your vehicle, the Pollak # PK12711U mounting bracket fits this socket perfectly. It keeps the plug secure and easy to reach so you can connect and disconnect quickly when hitching up different trailers.

As good or better than any other Plastic plug. I used it for a non typical application but I think its a good plug.
I work in retail and my customer could not find this anywhere. Looked it up on your website and ordered it. Came to me fast and made my customer happy. Thanks!!
Fast shipping, good quality parts!
I posted a review for the female part am very pleased with both we used it for the electric controls on a chopper and they both worked out very well. Thanks again
We needed to replace the input of the socket for our 25+ year old sno-way plow on our 1998 Chevy Blazer. The repair shop told us parts were no longer made for this unit. With a little investigation on the internet, lo and behold, there it is. Ordered, recieved and mounted, viola, it's working great! YAY!
Product was just as described. And unbelievable shipping!!! It was shipped the same day I ordered...
I am pleased with product and will need more parts in the future from your catalog. Having delivery was big plus as the closest RV Parts & Repair dealer is now 50 miles away in Spokane ! Thank You.
Excellent folks with which to do business !! Great selection of quality trailer parts, good prices & quick service. Everything I needed to hookup to my Airstream trailer with a new solar panel. Very pleased !!!!
I was searching all over the Dallas/Fort Worth metroplex looking for a male 10 pin connector to mate to a 10 hole connector on a 1992 Holiday Rambler 5th wheel trailer. I spent two days going from RV stores, trailer businesses looking for the 10 pin connector. All the stores didn’t have the part or the weren’t interested in helping me. I finally ran into a gentleman who knew that a 10 pin connector existed but they didn’t have one. He directed me to etrailer and they had one. They shipped it to me and I got it in two days. Great service from sales to check out to shipping. Great Job!
These connectors completed the job of connecting my 4 camera CCTV backup system with multiplexer from my trailer to the truck cab. I needed nine wires to accomplish this function. It is too bad that you didn't carrying the 9 wire cable, but I found a company that carried it on the web.
Awesome product! Used it for wiring on my farm tractor.
