Ask the Experts about this Hopkins Wiring

  • Replacing a 6-Way Trailer Connector with a 7-Way Trailer Connector on a 2000 Chevy Silverado
    First, you can almost never wire by color because there is no standard for wire color/function. You have to test the wires using a circuit tester like # 40376 if needed. Also there are 2 different ways to wire a 6-Way: either the 12 volt hot lead will be in the center or the electric brake output will be in the center. I have included a link to our FAQ article on wiring that shows how the various connectors should be wired. Ignore the colors listed and wire the connector by function....

  • Solution for Towing a Trailer with Round 6-way on Vehicle and 7-Way on Trailer
    Yes, check out the Hopkins 6 Pole to 7 Pole Adapter part # 47435. This is an adapter that will go from a 6-way to a 7-way.

  • Will a 7-Way Round to 6-Way Adapter Work with a Semi Tractor
    A 7-way round pin on a semi tractor normally has different functions than a 7-Way round pole found on something like an RV. I have included a picture showing what the functions are on the 7-Way part of the adapter. If this matches what your semi tractor has then it will work properly. If your 7-Way has different functions, which you can check by using a circuit tester such as # 3008, then you will need to re-wire the 7-Way to match the adapter or install a different 7-Way that will match.

  • Recommended Adapter To Plug 6-way Trailer Connector To 7-Way Connector On 1998 Dodge Ram 2500
    We have just what you are looking for. If you have a 7-way blade-style connector on your Dodge, you can use part # 47549. This simply plugs into your 7-way on your Dodge and then the 6-way connector from the camper plugs into the adapter. I have attached a helpful article that shows trailer and vehicle connectors and what they all look like.

  • Converting 7-Pole on 2018 Mack Dump Truck to 6-Pole for Trailer
    What you will need to do is plug the Hopkins Trailer Connector Adapter # HM47445 into the 7-Pole on your 2018 Mack and test each pin with a Circuit Tester # 40376 so that you can map out what the functions should be. You will then want to use a 12V power source, like a typical vehicle battery, and test the 6 pins on your trailer. You can then swap any wiring on your trailer connector if need be. If the trailer that you are pulling has the standard trailer side 6-Way setup like the...

  • Availability of 7-way Round Pin to 7-way Blade RV Style Trailer Connector Adapter
    So you're needing a 7-pole round to 7-way RV (blade) style connector adapter, is that right? We don't have an adapter like that (due to the fact that the 7-way round pin connector is pretty rare these days), so the easiest thing to do would be to replace the existing 7-way round pin connector on your vehicle with a 7-way blade style connector like # PK11893 and a # PK11998 7-way pigtail. Or, if it's still needed, you could leave the existing 7-way round pin connector in place and tap the...

  • Availability of 6-Pole to 7-Pole Trailer Wiring Adapter
    We do offer one 6-pole to 7-pole trailer wiring adapter, part # 47435, which converts a 6-pole round (round pin) connector format to an RV blade-type 7-way. I linked our main page for all wiring adapters and you can click on the filters on the page to narrow the selection based on the type of 6-pole connector you are using. I also included a link to an article on trailer wiring that may be helpful to you.

  • Troubleshooting Trailer Brakes Locking Up with Voyager Controller and Hopkins Trailer Adapter
    I recommend trying to reset the leveling sensor on your Tekonsha Voyager # 39510. I have attached a clip from the instructions to show how this must be done. If you have already tried this and it doesn't work then the next course of action is to test and make sure the brake controller is getting the correct power and that it is operating correctly. Using a circuit tester, make sure that the black wire has constant 12V power and that the red and blue wires only receive power when you...

  • 7-Way Round to 6-Way Round Adapter Recommendation
    Sounds like you are looking for an adapter like the part # HM47445 which will go from a 7-way round on a tow vehicle to a 6-way round on a trailer. I attached a review video for more info on this as well. The adapter you referenced is for a 6-way round to a 7-way blade.

  • Does 7-Pole Round to 6-Pole Round Adapter Require Wires to be Connected
    A 7-pole round to 6-pole adapter, the Hopkins Trailer Connector Adapter # HM47445 will not actually require any wires - including the brake wire - to be connected to the adapter. You simply plug one end to your vehicle's 7-round connector and then plug in your trailer-end 6-round to the adapter. If you were referring to connecting wire to the Pollak Heavy-Duty, 7-Pole, Round Pin, Trailer Wiring Connector - Trailer End # PK11700 you would undo the retainer screw at the base of the connector...

  • 7-Way Round Pin to 6-Way Round Pin Adapter
    For a 7-Way round pin to a 6-Way round adapter you can use either # HM47445 or # HM47535. But if the 7-Way round you want to adapt is a big rig 7-Way then this adapter will not work properly because big rig trailer connectors have different functions. I have included a picture of the functions of an RV 7-Way Round pin connector.
