This is a great heavy duty single pole connector. I use it for power transfer to my dump trailer. It handles the current requirement just fine. Solid construction had held up well to mud, dirt, and water. Definitely recommend this product!

Ive installed one of the single pole receptacle on all three of or super duty trucks. Its so nice to be able to never worry about the dump trailer battery being dead. We also made jumper cables that plug into it so we can jump chippers and other machinery easily. This product has held up extremely well also. Still looks brand new after 1 year of use. There is a little plastic piece that is on the end of the pole inside the receptacle that fell off of all three receptacles. However, It doesnt seem to affect the function at all.



by:

I used the plug and receptacle to connect my truck batteries to supply 12 volts to my camper. It is hooked up using one of the Ford up fitter switches to activate a starter solenoid that that supplies 12 volts through a 00 cable to the rear bumper receptacle. By using an up fitter switch it only works when the key is on but supplies the full 14 volts to the camper with little voltage drop. I can charge the camper batteries from the truck without the noise of running the camper generator. The camper has a 2000 watt inverter that I use when under way so don’t have to turn on the gas to run the frig in transit. The product works great with only one comment. The female receptacle( truck end) has a nice rubber boot for the feed cable but no such provision on the plug end so must be thoroughly tapped.

Everything we purchased, work out very well for us. Ty!

Quality part. My only complaint is actually a suggestion; a template would have been handy. I spent 20 minutes creating a template to use for cutting out a hole for mounting directly in the body.



by:

Great product, very well built, just what I needed



by:

I only wish the description would have included the part and number for the seal and the spring
that fit on the back of the plug. I would have order the seal too.

  • 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 Single-Pole,...

  • 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...

  • Recommendation For Getting Power To A Trickle Charger On A Trailer With A 4 Flat Plug
    The best way to accomplish what you want this to do will actually be to upgrade the 4 Flat plug on the trailer to a 7 Way. If you use something like the Hopkins # H20046, you will not need to connect all the wires. You will just need to match your blinker/brake signal, running light, and ground wires to the ones on the plug and them run the black wire to the trickle charger. A junction box like the # 38656 will also make this task a lot easier. If you do prefer to keep the 4 Flat on the...

  • 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.

  • What Wiring Goes to Pollak Single-Pole, Round Pin Trailer Wiring Socket - Vehicle End PK11851
    While we don't offer it, what you'll need is 00 gauge wire for the Pollak Single-Pole, Round Pin Trailer Wiring Socket - Vehicle End # PK11851. You'll simply solder that size wire into the socket; that wire size can be found at any type of local hardware store.

  • Pollack Single Wire Socket # PK11851
    The # PK11851 Single Pole Round Pin Trailer Connector is designed to deliver power to a trailer. It's not grounded, because the battery on the tow vehicle is already grounded and trailer mounted equipment is usually grounded as well. The ground connection would typically be carried through an additional connector; depending on the piece of equipment you are supplying power to you might need to increase the ground wire gauge. If you need the connector to power a winch, you would be better...

  • How to Wire Pollak 2-Pole Trailer Wiring Connector # PK12800
    On the 2-pole connector # PK12800 there is a set screw on the bottom, face end, of the connector. Remove this small screw with a flat screwdriver and you can pull out the terminals of the connector. On the other end you would route your wires (make sure the clamp set screw is loose) and pull them through to the now open end of the connector. Then you will solder the wires to the terminals. When finished, push the hole assembly back inside the housing and replace the set screw. Then tighten...

  • 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, # PK5231201, 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 that...

  • 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.

  • 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...

  • 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....

  • Male and Female Single Pin and 2-Way Pins for Trailer Wiring
    I think you may have your part numbers swapped around but the part numbers you mentioned all can work together. The 2-ways part # 337TC1002 and # 337TC2002 are perfectly compatible with each and the single pins # PK11851 and # PK11852.

  • Recommendation for Charging a Lithium Battery Bank From a 2009 Ram 3500 Diesel Tow Vehicle
    The Battery Isolation Solenoid # PK5231201 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 using...

  • Trailer Wiring and Method to Charge Trailer Battery on a 2005 1/2 Volkswagen Jetta
    For the 2005 and 1/2 model year VW Jetta, you will need a T-One Vehicle wiring harness, #118667, if you have the new body style. If you have the older body style, you will need the Hardwire Kit, # C59496. Since the wiring on the harness and your Jetta is not rated for a charging application, you will need to hardwire a connector specifically for this function. You could use part # PK11851, mount it on your vehicle. Connect 6 gauge to 00 gauge wire from the positive battery terminal...

  • 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.

  • Using a 7-blade RV Connection To Power a Trailer Mounted Winch
    I would not try wiring a winch through a standard 7-way connector. Winches draw much more amperage than the wiring that can be installed in a 7-way trailer connector can handle. 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...

  • How Does Wire Attach to Pollak Single-Pole, Round Pin Trailer Wiring Socket
    Single pole trailer connector # PK11851 accepts such large gauge wire that a set screw could work for holding the wire in place inside the connector. But it is designed so that you can solder the wire in. You can get a soldering iron kit fairly inexpensively just about anywhere that sells tools and/or craft supplies.

  • Max Wire Gauge Rating for Use with Pollak Single Pin Connector and Socket
    The Pollak Single-Pole, Round Pin Trailer Wiring Socket # PK11851 and plug part # PK11852 are rated for 300 amps of continous use like you mentioned. They can accept up to 00 gauge wire which is very thick.

  • 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.

  • Quick Disconnect Socket for Charging a Battery
    As long as you do not exceed the 300 amp rating of the Pollak Single-Pole, Round Pin Trailer Wiring Socket part # PK11851 then this would work for you. For the male end of the above socket you would want to use the Pollak Single-Pole, Round Pin Trailer Wiring Connector part # PK11852. The connectors can accept a wire size up to 00 gauge therefore, the 2 gauge wire will work well for you. I have attached a review video of each connector as well.

  • 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.

    When installing the Pollack # PK11604 you don't need to run a fuse inline with the battery on your trailer and you can run the power wire directly to the positive terminal on the battery. If you also need a vehicle end connector, I recommend using the Pollak Single-Pole, Round Pin Trailer Wiring Socket - Vehicle End # PK11851 I've linked a quick installation video that we did of this plug that doesn't use a fuse that I recommend having a look at.
