• Wiring US 4-Way Trailer Connector to Trailer with European 7-Way Trailer Wiring
  Since you want to go from a 4-way on your vehicle to a trailer with a European 7 flat, you will simply be able to use the Tow Ready Vehicle to Vehicle Tail Light Converter # 118158 (this doesn't work with LED lights). This will take the combined stop and turn signal wires on your 4-way and separate them for your European 7-way. You will connect the 4-way color-for-color and the running light will run around this adapter versus through it, and the ground will need to be spliced so it can...

• Tail Light Wiring Converter to Join European Motorcycle and U.S. Trailer Wiring Formats
  As you noted, trailers made for the U.S. use a combined wiring scheme for their lighting. Stop and turn signals for each side of the trailer are combined into one circuit and one wire. European wiring is different; it has all separate circuits. This is why there are no simple adapters that can join the two wiring standards and why converters are needed. Since your German-made Rewaco trike would be wired to the European standard you will need a converter to make it compatible with your...

• Converting European 7-Way on 2014 Volkswagen Golf to US Spec 7-Way
  You will need to replace either the connector on the VW or the one on the trailer. It would be easier to change the one on the VW because a US spec trailer has different functions than a European trailer and the functions would not match up. US trailers have combined brake lights and turn signals. A European 7-Way has a separate circuit for each light. Since your Golf already has a trailer connector all you will need to do is cut off the 7-Way end. Then you would use a convert to combine...

• Will the 7-Way Round Pin to 4-Flat Adapter Work On a Semi
  I do have an option for you but the 7-Way Round Pin to 4-Flat Adapter part # 47405 won't work on semi's as there is no converter integrated into the adapter. The lights on a semi are separate and the lights on a trailer are combined so a converter is required. Therefore, you will have to make your own adapter using the Hopkins Tail Light Converter part # HM48847, 7-Round Connector part # PK11700, and Hopkins Wiring Harness with 4-Pole Flat Trailer Connector part # HM48035.

• Using Separate Brake Lights and Turn Signals on a European Trailer with US Chevy Silverado
  The issue is that trailers in the US use a combined lighting system where the brake lights and turn signals are on the same circuit. European trailers have a separate circuit for each function. The wiring harnesses for US spec vehicles will take the separate brake light and turn signals and combine them for use with a US trailer. If you plug in a European trailer then it would function like a US trailer. To fix this issue you can install a converter on the European trailer. Converter #...

• 7-Way Commercial Truck Plug to 4-Way Wiring
  For a Commercial Truck 7-pin, you will want the 7-Pole Round Pin to 4-Flat Adapter # 47405. Then if you need extra length you can use the 48" Long 4-Pole Loop with Cover # HM47115.

• Does 7-Pole to 4-Way Trailer Adapter Have Converter Built In?
  The Adapter 7-Pole Round Pins To 4-Pole Flat # 47405 will not have the converter built in to combine your separated turn signals and stop light. That adapter will require a separate converter. For an option with the built in converter use the Pollak 7 Pole Round Pin to 4 Pole Flat Wiring Adapter # PK12742.

• Adding Fog and Reverse Lights to ISI-1185 Socket
  You may be able to add either the fog lamps or the reverse lights -- but not both -- using the center pin on your current socket. That is, as long as the center pin isn't being used on both the trailer and the truck. To add the other function you will need a separate connection since all other pins are being used.

• Are Diodes Needed If Vehicle to Vehicle Tail Light Converter 118158 Is Used to Tow European Trailer
  You will not necessarily need diodes because the back feeding would only be slight and should not be enough to cause any problems. But if you wanted you can still use diodes, # RM-690, one on the right turn/brake and one on the left turn/brake circuits on harness 18252. Basically, they will go before the # 118158 harness on the green and yellow wires.

• 7-Way to 4-Pole Adapter Not Functioning When Installed on 2001 Land Rover Discovery II
  I'd begin by testing the 7-way on the Land Rover. The trailer wiring FAQ I've linked you to will show you which pins on the 7-way will show voltage as each turn signal/brake lamp/ running lamp function is activated. Make sure the 7-way is wired as shown in the FAQ. Then, plug the adapter into the 7-way and test each function. If you don't have a circuit tester, we offer one as part # PTW2993. Usually when you have both turn signals operating at the same time, it indicates a ground problem....

• Changing a US Style 7-Way Vehicle Connector to a European Style 7-Way Connector
  The European 7-Way does the same thing that the US 4-Way does. There isn't an adapter available because the European 7-Way has separate circuits for nearly every function on each side of the trailer. The US style 4 or 7-Way has combined brake lights and turn signals. What you will have to do is change over the US style 7-Way to a European one. You will need 1 European style vehicle side 7-Way and one special converter that separates the combined signals to separate ones. You will need...

• Recommended Adapter to Connect 7-Way Round Pin to 4-Flat Connector
  The Tow Ready 7-Pole Round Pin to 4-Flat Adapter # 47405 referenced in your question is designed to adapt a 7-way round pin to a 4-flat connector that you can hookup to a trailer that has a 4-way. If this is what your trailer uses, and your existing 7-Way round has the traditional pins as depicted below, then this will work great. I am not positive how you were connecting the harnesses before, so I can't be sure as to why the brake lights were not working. This adapter will provide an...

• Can a European 7-Way Trailer Connector be Converted to a U.S. 4-Way
  You have 2 options. First you can convert the Ford Focus wiring harness, after installed, to match the trailer. Or you can convert the trailer connector to match the vehicle connector, once it is installed. The easiest thing to do would be to convert the trailer but there may be certain lights and functions required in Europe that are not required in the U.S. I will try to cover both ways for you but there is no simple adapter for either method. To convert the vehicle, first you will...

• Wiring Headache Rack Lights To The 7-Way Of A 2021 Chevy Silverado 3500
  To alleviate your headache rack issues you'll need to pick up some resistors with part # DI34ZR along with a 4-pole pigtail like part # 002220. You'll splice the resistor into the wiring for the headache rack and then splice on the 4-pole pigtail and can run it out to your 7-way and use an adapter like part # 47405 to plug in. I recommend using some heat shrink butt connectors # DW05744-10 to properly seal your connections and prevent corrosion.

• Adding 4- to 7-Way Adapters on a 2000 Toyota Tundra and 2013 Toyota Sienna with 4-Ways
  Adapter # 47405 is probably not the adapter you need. It would plug into a 7-Way round pin connector on the tow vehicle and allow you to plug in a trailer that has a 4-Way flat connector. Since both of your tow vehicles have a 4-Way flat you will need different adapters. Also, there are 2 kids of 7-Way connectors. One has round pins like # PK11720 and the other, much more common and probably what the trailer will plug into, is a blade style like # PK11893. If the trailer has a 7-Way then...

• Light Kit to Flat Tow a 2015 Ford F-150 Behind a Motor Home
  For your 2015 Ford F-150 you can use 4-diode kit # RM-154. This is a more permanent installation that does require tapping into the vehicle wiring. For a more temporary solution you could use a magnetic kit such as # RM-2120 but you would need to also use tow light partners # TLP01 because of the aluminum used in the 2015 Ford F-150s.

• After Installing Tow Bar Wiring Harness HM56000 on 2008 Ford Edge Brake Lights Do Not Work
  You will want to unplug the 2008 Ford Edge from the motor home and use a circuit tester, such as # PTW2993 if you don't have one, to test the motor home side trailer connector. First test it without the adapter plugged into the 7-Way. Have someone sit in the motor home and go through the light functions while you test with the circuit tester. If the brake light signal is not coming through, then there is likely a blown tow package wiring fuse or wiring issue on the motor home you will...

• Wiring Adapter for Kabota Tractor To Use Standard 4-Way Trailer Connector
  Yes, the Adapter 7-Pole Round Pins To 4-Pole Flat part # 47405 will work on your Kabota Tractor. The tractor has what is called an agricultural 7-pole which is pretty common. I know it is hard to tell from the photos but the ground terminal on the above is larger than the rest and will match up to that on your tractor so you should not have any fit concerns. This adapter will then let you power a trailer with standard 4-flat.

• 7-Way Round to 4-Way Adapter with Thicker Ground Pin
  The pin sizes on your 7-way round connector are standard so what that means is that a standard 7-way round to 4-way adapter like the part # 47405 that you referenced would work Tom.

• 2015 Ford Transit T-350 Van Trailer Connector not Working What Should I check
  From what I understand your 2015 Ford Trasit T-350 has a connector on the back for use with trailers that looks similar to the Custer Trailer Connector part # KIT-7P-4 and you have added an adapter similar to 7-Pole Round Pin to 4-Flat Adapter part # 47405 to plug your 4-way flat trailer plug into and you are getting no power to the lights at all. This sounds like a pretty common issue we run into often. That being the ground wire. This could have been damaged or has corroded at the connection...

• Using a Taillight Converter to Wire a 2008 Chevy Uplander for a European 7-Way Trailer Connector
  There are 2 ways you can tow the European trailer with a US 4-Way flat connector. You will either need to change the connector on the vehicle or change the connector on the trailer. Depending on which one you choose the converter # 118158 will either be on the vehicle side or the trailer side. No diodes are needed. 1). With your current setup, you will not need any diodes. The intended purpose of the diodes when used in conjunction with the taillight converter # 118158 is for a flat towing...

• Parts Needed to Flat Tow a 2016 Ford F-150 King Ranch with LED Tail Lights Behind an RV
  For tow bar wiring for your 2016 Ford F-150 I recommend going with a magnetic kit # RM-2120. The issue is that the diode kits and converters that go with them are not rated for use with LED tail lights. The best option then is going to be a magnetic kit. And having a wireless system means you won't have to run any wires or worry about complicated installations on the truck. Since the lights are magnetic you may need to use tow light partners # TLP01 in the windows of the truck if the lights...
