• Troubleshooting Wire Functions On Trailer With 6 Wires
  With 6 wires on your trailer, we have a good idea what they go to, however you will want to test the functions. You can use a 12V battery and connect each wire individually on the positive terminal while the negative terminal is connected to ground. I've attached a wiring diagram to help you with functions and traditional colors, however many trailers will have colors that do not match function represented in this article so don't be thrown. That is more common than you think. Traditionally...

• Which Wire is the Ground Wire on Sundowner Horse Trailer 6-Way
  Between those two color choices the black one would most likely be the ground wire. However, if you hook it up with the black as the ground and it does not work I would recommend trying the red wire. Also, you should trace both of these wires back on the trailer to see where they terminate. The ground wire should be connected to the frame of your trailer. Whichever one connects to the frame is the ground. The ground wire should be wired to the 12 o clock position terminal on the Pollak...

• Running Lights On Trailer Stay On After Truck Is Turned Off
  Hello Timothy. There are many possible reasons why the running lights on your trailer stay on when your truck is off. The most common cause of this is a bad ground so double check to make sure your grounds are attached to completely bare metal surfaces and free of any paint, dirt or corrosion. Another possible cause is if your trailer has LED lights they can stay lit dimly. This is not uncommon for some LED lights and the only solution for this is to unplug the trailer.

• What Function is Carried on Center Pin of 6-Way Round Trailer Connectors
  A 6-way round-pin trailer plug like Pollak # PK11604 has a center pin that can be wired in two ways. The most common function to be found on that center pin is 12V trailer power. This is a low-level maintenance charge that will maintain a charged trailer battery while you're driving. In other applications this center pin will carry the trailer brake signal from the brake controller mounted in the tow vehicle. Please refer to the linked photo that shows both inside and outside views of...

• Trailer Taillights Do Not Work When Connected to 2001 Ford Van 6-Way Connector
  The white ground wire should attach to the pin on the vehicle 6-way connector that is located at the 2-oclock position. Please take a look at the photo provided; this is labelled to show to which pin the ground wire should attach. Since you have two white ground wires, it sounds like a second ground jumper wire has been added to provide a better ground connection. A ground jumper wire should connect on one end to the same spot on the frame as the main ground wire and the other end to another...

• Tow Dolly for a Full Size Truck with Front Track of 79 and 78 Inches
  The best tow dolly we offer is the Roadmaster Tow Dolly with Electric Brakes part # RM-2050-1. Dolly includes all lightging as well for DOT compliance. The only thing one would need to use this dolly is a trailer connector like part # PK11604 for a 6-way or part # PK12706 for a 7-way. This dolly will accept a vehicle with a front track up to 76" wide which would seem to be a bit too narrow for your application. The dolly also only accepts wheel sizes from 12" - 16" therefore would also...

• Can a 2013 Suzuki Grand Vitara be Towed Behind a Motorhome and Parts Needed
  From what I could find online it looks like you can flat tow your 2013 Suzuki Grand Vitara as long as it is a 4WD with a transfer switch. If it is a 4WD without a transfer switch then you need to use a trailer to keep all of the wheels off of the ground. For a 2WD you can tow it using a tow dolly with the rear wheels off of the ground. You will want to verify this and specific instructions in your copy of the owner's manual. If you have a 2WD then I recommend using the Roadmaster Tow Dolly...

• Adapter for a 4-Way Flat Vehicle End Trailer Connector to 6-Way Round Pin Trailer Connector
  If you only want to use the basic lighting functions provided by the 4-Way (left/right turn, brake, and running lights) then all you will need to do is plug the 4-Way end of the Adapter 4 pole top 6 pole, # A10-6034VP, into your vehicle 4-Way. The trailer 6-Way will then plug into the 6-Way receptacle on the adapter. You will also need to ground the white wire on the adapter to the vehicle frame at a clean and corrosion free metal surface. The remaining wires (blue for electric brakes and...

• 6-Way Extension Harness To Connect Vehicles For Flat Towing
  We do have the Hopkins Heavy-Duty Trailer Coiled Extension # HM47055 that is also 8' long when stretched like the Hopkins 6-Way Connector with Jacketed Cable # H20036 that you found. The coiled cable will help to prevent the excess cord from dragging on the ground.

I have included a video linked below that will walk you through...

• Can a 2004 Subaru Outback be Flat Towed and Parts Needed to do so
  I looked up the online versions of the owner's manuals for your Forte and your Outback Wagon. It looks like the 2013 Kia Forte can be towed with a Tow Dolly but the 2004 Subaru Outback Wagon can be flat towed. You will want to verify this with your copies of the owner's manuals or local dealer. I couldn't find an online manual for your 1988 Dodge Dakota so you would need to look that up or contact your local dealer for info on that vehicle. If you let me know which of the 2 vehicles I...

• Why Do the Trailer Brakes Lock Up When 6-Way Connector Is Plugged Into Ford Truck
  A 6-Way round pole connector can be wired one of two ways; with the center pole as the 12 volt hot lead, or as the brake. Having the center pole as the 12 volt hot lead is probably most common. In your case, the 6-Way round connector on your Dodge is probably wired with the center pole as the brake lead. The Ford is probably wired with the center pole for the 12 volt power. When you plug in the connector to your trailer and the center is 12 volt power it is just going to lock up the brakes...

• Looking for Trailer Connector at Lease 32" Long that has a 6 Pin Male Connector on Both Ends?
  Hello Tim, When you say you are looking for one with a 6 pin male on either end, do you mean that you need them on both ends? In order for you to have a trailer connector with (2) 6 pin males, you will need the Hopkins 6-Way Connector with Jacketed Cable - Trailer End - 8' Long # H20036, then add # PK11604 to the open end. If you are talking about a flat tow set-up, usually on the back of the RV you will have a 7 blade, then the front of the tow vehicle a 6 pin, if that is what you...

• Installing a 7-Way Trailer Connector on a Trailer with 6 Wires
  You can certainly add a 7-way trailer connector to your trailer with 6 wires. You would simply have 1 pin on the 7-way connector that did not function. I recommend adding a 7-way molded trailer wire connector like part # H20046, and a junction box like part # 38656. We do this on all of our trailers and our customers trailers and it will make future wire maintenance much easier. I have attached an installation video of these two parts for you to check out. Once you have all of your parts,...

• Wire Missing For 7-Way Trailer Side Connector
  I have attached the wiring diagrams for the different 7-way connectors used on trailers. I find it best to not reference wiring by color but instead function since depending on who made the wiring harness and who wired the trailer they can vary. As the white wire is typical of a ground connection the person who wired the trailer the first time may have not used it hoping that the ball connection would provide the ground that they needed to the vehicle. You may need to replace the 7-way...

• Diagram to Use When Wiring 7-way in Place of 6-Way on Horse Trailer
  Your best option is going to be to use the wiring diagram I attached for 6-ways to identify the functions of the wires from the picture you sent in and then wire them according to the labelled pins on the new 7-way similar to the # HM48502 and you'd be set. Use the set screw that you see in your picture as the "top" when comparing what you have to the wiring diagram. The center pin is the 12 volt circuit on the 6-way and if you have no use for it (it has nothing to do with brake controller)...

• Installing 7-Way Trailer Connector in Bed of 2006 Chevy Silverado 2500
  Assuming that the 7-way on the bumper is from the factory and the tow package harness can be unplugged from the rear of the connector, using a T-connector like # 41157 is what I'd recommend. Simply temporarily unplug the connection at the rear of the factory 7-way and plug the # 41157 inline as shown in the linked video.

• How to Tell if Trailer Has 6-Way or 7-Way Installed
  It sounds like you have a 7-way blade connector on your boat trailer as that is a very common connector on boat styles. This connector has 6 pins around the outside of the connector and a center pin for a total of 7. Part # A7WCB would be what a 7-way would look like. If you had a 6-way it would look like part # PK11604.

• Using a 6-Way to 7-Way Adapter for a RV with 6-Way Round Socket and Trailer with a 7-way Connector
  The Hopkins 6 Pole to 7 Pole Adapter, # 47435, does have a pin for the brake output for a brake controller. This adapter will work for your set up as long as the center pin of the 6-way plug on your RV is for 12v power and the pin in the 10 o clock position is for the brakes. You can verify this using a circuit tester like part # PTW2979. If the center pin on your 6-way plug is wired for brakes and the pin in the 10 o clock position is for 12v power, then you can still make an adapter...

• 6-Pin Round Vehicle Connector To 7-Pin Round Commercial Trailer Connector
  I have a couple options as there is not one adapter from a 6-pin round vehicle connector to a 7-pin round commercial trailer connector. The first will combine a Adapter 6-Pole to 7-Pole Trailer Wiring Adapter # 47435 and a Pollak Trailer Connector Adapter # PK12727 to adapt your connections. Or you can wire in a Pollak 6-Pole, Round Pin, Trailer Wiring Connector # PK11604 to a Pollak Heavy-Duty, 7-Pole, Round Pin Trailer Wiring Socket # PK11720. This will create your own wiring adapter....

  Sounds like your trailer wiring does not have a ground circuit for it's connector. The easy solution for that is to run a wire from the ground pin of the connector to the trailer's frame. Your trailer electronics should work a little better now as previous to this it was grounding through the ball mount.

• How To Repair An Electric Trailer Brake That Is Missing One Wire
  If one of the brakes on your trailer is missing a wire, you will have two options. First will be to replace the magnet. This will depend on what size brakes you currently have installed, but the Replacement Magnet Kit # AKBRKR-M10, as an example, will come with everything needed to full replace the magnet and wires on a 3,500 pound capacity, 10" electric brake. This will work perfectly, but can be a bit of a pain to do. The easier way, and also the way I recommend, is to just replace the...
