Solid and simple construction make this a great plug for rugged high amp application. I use this for power transfer to my dump trailer and it works great! Definitely recommend this product.!

I LOVE these! I need to run power to my car hauler and had to replace the cheap single pole cable I bought at the truck shop since both connectors (cheap cast aluminum) broke in only a few weeks. I've used this connector for years and it is easy to dis/connect EVERY time, and it's thick brass case does NOT break. If you need reliability, and can't afford to have a work stoppage, this will be what you need.


Comments
A year later, the connects are still doing just fine. Since they are exposed to the weather and road spray I spray them out with brake cleaner and reapply a little dielectric grease to them and have never had so much as a hiccup from this great product.

Use on all of my trailers with winches. Very durable and better than plastic plugs companies like to use with winches. Only down fall you have to sodier power wire into center power pin

Ask the Experts about this Pollak Wiring

  • Is the Ring Terminal Attached to the Housing of the Pollak Single-Pole Connector a Ground
    Yes, the ring terminal you see attached to the housing of the Pollak Single-Pole, Round Pin Trailer Wiring Connector # PK11852 that you referenced is used for a ground circuit. Check out the picture I attached that came from a customer who used this to install his winch. You can see the black (ground) wire run to the ring terminal.

  • Does Travel Trailer Battery Connector Need to Have Ground Connection
    Yes, whether you plan on using the Pollak Single-Pole # PK11852 (which is geared more towards winches) or the Mighty Cord 7-Way RV Style Trailer Connector # A10-7081VP (which is recommended for a travel trailer), you will not only connect the power wire but you also need to have a ground connection as well. The single pole connector has a ground connection on top of it while the 7-Way has a pin designated for the ground (see attached picture).

  • Socket and Connector Recommendation for Charging Battery Bank of Trailer
    The part # PK11852 and # PK11851 can be used for charging a trailer's battery. You would not be completing a circuit on the trailer since it's running to a battery so all you'd need to do is run the charge wire to the battery and you'd be able to charge it.

  • Why is the End of the Pollack Single-Pole Trailer Connector # PK11852 Threaded
    The threaded end of the Pollack Single-Pole Trailer Connector, # PK11852, is for the Pollack Plated Steel Cable Guard, # PK11763. The cable guard prevents incoming wires from crimping and includes a loop to hang the connector when it is not in use.

  • Single Pole Trailer Wiring Connector for Battery Charge Line for RV
    If you are looking for a single pole connector to use as a charge line for the batteries of your RV the part numbers # PK11851 and # PK11852 would be a great choice. These connectors can accept wire gauge up to 00.

  • Can 2 Gauge Wire be Used with Pollak Single-Pole, Round Pin Trailer Wiring Connector
    A 2 gauge wire is only a little smaller than double aught (2/0) by about 0.11 inches diameter so it could be used in connector # PK11852. But I advise soldering in the wire and not crimping it for the best results. Triple aught (3/0) would be too large to fit.

  • Recommended Wiring and Installation Instructions for Winch
    Single-Pole, Round Pin Trailer Wiring Connector, # PK11852, which you reference, uses #OO gauge wire, which we do not carry at this time. The best solution would be to use a winch wiring kit like the Winch Trailer Wiring Kit, item # BDW20043. This kit includes everything needed to install a connector at the rear of the vehicle and at the front of the trailer, for powering a winch. If you already have heavy enough gauge wire you can order the Electrical Quick Connectors, item # DL24086. For...

  • Trailer Plugs Compatible with 1 and 2 Pole Pollak Trailer Sockets
    Both trailer connectors you speak of are sockets that would typically be used on the vehicle end of the trailer/vehicle connection. One is a one pole, the other a two pole so they wouldn't be compatible with each other. The Pollak # PK11851 is a single pole wiring socket, which would be compatible with a # PK11852 single pole plug The Pollak # PK12801 2-pole socket would be compatible with a 2-pole plug, part # PK12800.

  • Higher Amperage 12 Volt Power Connector to Use at Rear of 2020 GMC Sierra 1500
    For a higher amperage connector setup you'd want the single pole part # PK11851 with the matching male side part # PK11852. This has a 300 amp rating so you'd be perfectly fine to run basically anything you'd want from it. The connector you mentioned is limited to only 10 amps. I'd go with 8 gauge or thicker for maximum amperage as well.

  • Recommendation for Charging a Lithium Battery Bank From a 2009 Ram 3500 Diesel Tow Vehicle
    The Tow Ready Battery Isolation Solenoid # TR118665 along with 00 gauge wire and Pollak Single-Pole, Round Pin Trailer Wiring Socket # PK11851 along with # PK11852 will allow you a great connection for charging your battery. I also recommend putting a 40 amp circuit breaker # 9510 in line to protect your system. The issue is it will not amplify your charge so you will still be limited to the 2-3 amps charging above what your truck uses from your alternator. For a better option, I recommend...

  • Parts Needed to Charge a Trailer Battery for a Winch
    First, the wiring on a trailer connector can provide a maintenance charge to a 12 volt battery on a trailer but it will not be able to fully charge it. The 12 volt circuit on a 7-Way is already circuit protected so a separate fuse or breaker should not be needed. There is a way you can provide a charge to the battery from the truck. You would need to equip the truck and trailer with separate single pole connectors independent of the 7-Way. For the trailer side, you would need Pollak...

  • Wiring Options for an Electric Winch Powered by an Additional Battery
    The easiest way to wire the battery for your winch will be to use the 7 way connector on your vehicle if you have one on your 2006 GMC Truck. You can get a 7 way trailer connector like part # A7WCB and use the Jacketed 2 Wire, part # 10-2-1, to connect a wire for the power and a wire for the ground in the connector. You will then run the ground wire, or white wire, to the negative terminal on the secondary battery and run the power lead, black wire, to the positive terminal on the battery....

  • Troubleshooting Roadmaster Even Brake # RM-9400 Detects Low Battery Voltage on a Charged Battery
    There may be some sort of feature on the vehicle that reduces power if it is not running but I would think it would cause the low voltage message again after you have turned the system off again. You may need to connect the Even Brake, # RM-9400, to a different power source and see if that fixes the problem. The troubleshooting pages in the instructions only state to make sure the red wire on the ICX transmitter is connected to 12 volt power and the white wire is connected to a ground...

  • How to Charge Two 12 Volt Batteries on an RV Towed by a Ford F-150
    The 12 volt circuit on a 7-Way trailer connector can provide a maintenance charge to a 12 volt battery but it will not be able to fully charge it because the wiring for a 7-Way is too small to carry the current required. What you can do to charge the batteries on the RV is to first install a battery isolator, # TR118665, in the truck. You will need to attach one terminal to the positive on the truck battery and then connect the center terminal to a 12 volt ignition source (something...

  • How to Charge a Trailer Battery While Towing a Tear Drop Trailer with a 2002 Volvo v70XC
    If your trailer has a 7-Way connector, then it either already has electric brakes or is set up for electric brakes. Either way, you would not want to use the pin and wiring for the electric brake to charge a battery because it is too small a gauge for this application. A 7-Way connector already has a pin for a 12 volt accessory. If you are looking at the face of the trailer side 7-Way, it is in the 11 oclock position. This wire is only large enough to maintain a battery but will not charge...

  • How To Run Large Gauge Wire Between Truck and Trailer
    The only option we can offer to run a large gauge wire between the trailer and tow vehicle is with the Pollak Single-Pole, Round Pin Trailer Wiring Socket part # PK11851 and the Pollak Single-Pole, Round Pin Trailer Wiring Connector part # PK11852. The standard 7-way terminals will only accept wires up to 10 gauge on all but the ground circuit.

  • Can the Ultra-Fab 4K Electric A-Frame Jack Be Powered From the Vehicle
    Yes, the Ultra-Fab Electric A-Frame Jack part # UF38-944016 can be powered from the tow vehicle's battery. I suggest simply attaching a trailer connector to the end of the power wire and extending if needed, similar to the etrailer Electric Jack with Footplate and 7-Way Plug part # EJ-3527-BBX. That said, the Ultra-Fab pulls more power than the etrailer so you really can't use the 7-way socket due to the wire gauge difference. I recommend installing part # PK11852 on the jack and part...

  • How Charge Trailer Battery With Truck While Using Winch
    The 12v power pin on the 7-way connector of your 2012 Chevrolet Silverado will provide a small maintenance charge to your trailers battery, but will not be able to support it using a winch. The only option to keep it charged when using something that draws a lot of power like a winch would be installing a heavy duty single pole connector # PK11851 on the truck and the trailer side # PK11852 on the trailer. These connectors will work with 00 gauge wire and you will need to run that wire...

  • Using the 12 Volt 7-Way Circuit for Off Road Lights on a Trailer
    This sounds like a power draw issue. The 12 volt circuit on your 7-way is only designed to provide a certain amount of amps which will vary depending on the vehicle but it is usually around 20-40. If the power draw of your off road lights exceeds this then that is what would cause them to cut out. It may be best for you to just run the off road lights directly to the battery with a quick disconnect in between the trailer and tow vehicle. For quick disconnects I recommend part # PK11852...
