Video Transcript for Pollak Wiring - Trailer Connectors - PK11851 Review

Today we're going to be reviewing part number PK11851. This is the Pollak Single Pole Round Pin Trailer Wiring Socket. It's going to feature a nice, rugged design. It's going to be ideal for heavy-duty power applications. It's going to supply your power straight from the vehicle battery. So again, heavy-duty applications, supplying auxiliary power straight from the vehicle battery. It's going to feature a round removal pin for easy soldering.

It's going to be held on there with a couple of screws at the back. Now here up front, it's going to feature a nice, spring-loaded lid. This is going to feature a corrosion-resistant plating that's going to help keep any dirt and moisture out of that connection point. It's also going to feature a two-hole mounting design. If we take a measurement between the mounting holes center on center, it looks like that's going to give us a measurement of about 3 inches. Now, those mounting holes are going to measure 5/16ths of an inch by 7/16ths of an inch. This unit's going to have a current rating of 300 amps of continuous duty capacity. That's going to do it for today's review of part number PK11851.

This is the Pollak Single Pole Round Pin Trailer Wiring Socket. .

Ask the Experts about this Pollak Wiring

  • 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.

    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.

  • 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...

  • Does the Pollak Single-Pole Trailer Connector Provide a Ground Connection
    The # PK11851 Single Pole Round Pin Trailer Connector is designed to deliver power to a trailer. It is not grounded, as the battery on the tow vehicle is already grounded and trailer mounted equipment is typically 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 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.

  • 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.

  • 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...

  • 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.

  • 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....

  • 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...

  • 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...

  • 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 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...

  • Will the 7-Pole Rubber Socket Boot Fit on the Heavy-Duty, 7-Pole, Round Pin Trailer Wiring Socket
    Yes, the 7-Pole Rubber Socket Boot, # PK11761, works with 3 of the Pollak heavy duty wiring sockets that we carry. You can use it with part # PK11720 that you mentioned and it can also be used with part # PK12801 and # PK11851. The hole in the back of the boot is just under 7/16 inch and measures .425 with a dial caliper. I produced a short video showing how the boot fits on each item for you.

  • 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 To Create a Separate Battery Charge and Light Trailer Connector for a Truck Bed Camper
    I do have an option for you but most of the standard trailer connectors are not going to handle an 8 gauge wire very well as it is just too large. Therefore, your best option as you mentioned would be to just run the lights and battery charge line on separate connectors. I have attached some parts you will need below for the above option.

  • 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...

    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 Upgraded Circuit Protected Tail Light Conversion Hardwire Kit, # 119178KIT, from Tekonsha. I've included a video of each. 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,...
