Ask the Experts about this Pollak Wiring

  • Converting Separate Turn Signals and Brake Lights on a Motor Home to Combined to Use a Light Kit
    I will be happy to help you out. The separate brake light circuit is going to have to be combined with the turn signals in order to use a light kit with a 4-Pole connector. There is a special converter for this, # RM-732. On the input side you will connect the right turn signal wire to the green lead, the left turn signal wire to the yellow lead, and the brake light wire to the red lead. The converter will properly combine the signals and on the output side you will have green for right...

  • Trailer Wiring Adapter to Convert 4-Pin Round Vehicle Connector to 4-Pole Flat Type
    Thank you for providing the photo of the 4-pin round trailer connector on your vehicle. We do have two different products that will adapt this connector to a standard 4-pole flat trailer connector. Hopkins offers their adapter # 47465 (that can be used with mounting bracket # 18144) and Custer offers their adapter # ADP001 that does not require a mounting bracket.

  • How to Make 6-Way to 5-Way Flat Trailer Connector Adapter
    A 6-way round to a 5 flat can be made but since the demand for this type of adapter is very low none of our manufacturers offer one. What you would need is 5-way vehicle side with lead like # HM47900 and then wire it to a 6-way plug part # PK11604 and you'd have the adapter you'd need.

  • Troubleshooting Trailer Wiring of 2006 Dodge Ram 2500 Where Turn Signals do Not Work
    The trailer wiring of your 2006 Dodge Ram 2500 SHOULD have the turn signals already combined since that is the standard wiring and Dodge has always abided by same wiring setups. Your generation of Dodge truck doesn't use traditional fuse/breakers for circuit protection of the trailer wiring and instead has all of that integrated into the TIPM of the vehicle. The only way you can get that reset is by going to a Dodge dealer. We do have a solution that allows you to bypass that if you...

  • Recommended 6 Pole to 4 Pole Connector Adapter
    I may have a solution for you, however we do not currently have any 4 pin wire harnesses that feature a 6 wire pigtail. If you are needing to convert a 6-Way connector on your vehicle to a 4-Way flat in order to connect with your trailer, I recommend using the Pollak Adapter # PK12717. This adapter will simply plug into the 6-pole, round pin connector on the vehicle to provide a 4-pole flat connector. It will connect the ground, left turn, right turn, stop and tail light circuits.

  • 6-Way Recommendation for Trailer and Tow Vehicle
    For the trailer side 6-way you would want the part # PK11604 and then for the matching socket you would want the part # PK11609. We don't carry any grommets for the vehicle side 6-way that you referenced and the part # 118152 would be a great choice for storing the 6-way.

  • Need to Adapt 6-Way Connector on Motor Home to 4-Pole Round Tow Bar Cable
    I would recommend installing a 4-pole round socket, part # PK11404 on the rear of the motor home, rather than trying to construct an adapter. The socket would need to be tapped into the wires feeding your 6-way. We offer 4 conductor wire, part # 16-4B-1 that is sold by the foot, you would probably want at least two feet. The wire is conveniently color coded, and would attach to the 4-pole socket as follows: Attach the brown wire to the # 2 terminal. Terminal # 1 would be grounded to...

  • Wiring an RV with Separate Brake and Turn Signals to a Chevy HHR with Combined Brake/Turn Signals
    Probably the easiest solution is to first use a 6-Way to 4-Way adapter, like # PK12717, and plug the 6-Way side into the motor home. Next, add a light kit to plug into the 4-Way flat part of the adapter, like Magnetic Towing Light Kit, # C-ATL20A. Mount the lights on a metal surface on the HHR and you have lights for towing your HHR. For a more permanent solution, you could install the Tail Light Isolating Diode System with Wiring Harness, # 38955. After installing the diodes, plug the...

  • Flat Tow Wiring Harness for a 2017 Jeep Cherokee
    For a wiring harness that will allow your motorhome to activate the taillight on your 2017 Jeep Cherokee, I recommend using the Hopkins Custom Tail Light Wiring Kit for Towed Vehicles part # HM56208. The Hopkins harness is a direct plug and play option that will not require you to cut or splice any wires on your Jeep. If you have a 6-pole trailer connector on your motorhome which most do, then you will also need the Pollak 6 Pole to 4 Pole Connector Adapter part # PK12717. I have attached...

  • Recommended Converter For Winnebago To Combine Turn And Stop Signals For Trailer Connection
    To take separate turn signal and brake signals from your motorhome and convert them to combined for your trailer connection, I recommend the Upgraded Circuit protected converter that is powered by the battery # 119178. This will need to be installed before your 6-way trailer connection and will allow you to simply use an adapter like # PK12717. I've attached a photo to help you with wiring locations on your 6-way trailer connector.

  • Recommended 6-Way to 4-Flat Adapter for Towing Trailer Behind Itasca Motorhome
    In order to take the separate brake lights and turn signals from your Itasca Motorhome and convert them to the combined circuits for your trailer, I recommend using the Tekonsha Upgraded Circuit Protected Tail Light Converter # 119178. This will be powered by the battery and will install before the 6-Way trailer connection. You can then simply use a 6 Pole to 4 Pole adapter like the Pollak # PK12717 to connect with the trailer. I have included an image that shows the wiring locations...

  • Why Does a 6-Way to 4-Way Adapter Only have 4 Contacts
    An adapter such as # 37325 or # PK12717 will only have the necessary pins required by the 4-Way end. These are the basic lighting functions; left/right turn signals, brake lights, and running lights. And the 4th is the ground (the turn signals and brake lights are combined on the same circuit for each side of the trailer). A trailer that uses a 4-Way flat connector does not have the other functions on a 6-Way. If the connector on your 2004 Jeep Grand Cherokee is factory then it is likely...

  • Adapting a 7-Way Trailer Connector on an RV to a 4-Way Flat on a Towed Vehicle
    If the coach uses the 7-Way RV style connector with blade style pins then you can use coiled adapter, # HM47065, with the Hopkins Custom Tail Light Wiring Kit, # HM56000, or similar tow bar wiring that has a 4-Way flat end. If the coach has a 7-Way round pin connector then you can use an adapter such as # 118709. But you will likely need a 4-Way extension, # HM47115, to reach from the front of the vehicle to the coach. If your coach has a 6-Way round pin connector then you would use...

    There are many products to adapt a 6-pole round vehicle connector to a 4-pole flat trailer connector. One such item is the Pollak 6 Pole to 4 Pole Connector Adapter, part # PK12717. This nylon housing adapter simply plugs into your 6-pole connector. Another product you might consider is the Hopkins Endurance Flex Trailer Connector Adapter w/ LED Circuit Tester - 6-Pole to 4-Pole, part # HM47320. This adapter includes a 5 inch flexible wire between the 6-pole and 4-pole connectors that...

  • What Adapter Do I need to Convert the 6-Way to a 4-Way on my 2010 Chevy Avalanche for a Hitch Cover
    For a 6-Pole Round connector, you would use adapter part # PK12717. Most of the manufacturers use 7-Pole connectors, not 6. There are 6 flat pins arranged in a circle with a large center post as the 7th contact. In this case, you would use part # PK12716. Check the pictures of the parts I mentioned and you should be able to tell which is on your truck. I just do not want you to end up with the wrong part.

  • Using Lighted LED Chevy Bow Tie Hitch Cover on 2005 Chevy Silverado with 6-Way Trailer Connector
    Trailer hitch cover # RP86530 comes with a 4-Way but not an adapter. You would need to order an adapter separately. A 6-Way trailer connector is not too common on vehicles like your 2005 Chevy Silverado. Doublecheck to make sure it isn't actually a 7-Way such as # PK11893. If you do have a 6-Way you can use adapter # PK12717. If it is a 7-Way you can use adapter # PK12716.

The tow bar comes with safety cables and a 6-pole connector. Both the towing and towed vehicles will need a RoadMaster 6-Wire Trailer Connector - Vehicle End, # RM-910030-7. Finally, you will need to check with the manufacturer for instructions on the proper procedure for towing your vehicle because some vehicles...
