Heavy Duty Magnetic Towing Lights for Flatbed Trailer Towed by 2017 Ford F-350

Expert Reply:

It sounds like you're trying to add some lights to a flat bed trailer being towed by a 2017 Ford F-350. If your 2017 Ford F-350 has a 4 way round pin plug installed (or you're willing to do some wiring), you can use the Heavy Duty Magnetic Tow Lights # 337TL257M which comes with a 4 way round pin plug and socket to install on your vehicle.

With that being said, I have a solution for you that won't require any additional wiring work. I recommend using the Heavy Duty Magnetic Tow Lights - 20' Wiring Harness with 4-Way Flat Trailer Connector # TL21RK since it comes with a 4 pole flat connector to plug into your vehicle.

If your F-350 has a 7 way connector on it without a 4 way connector integrated, you'll want to use the Pollak 7 Pole to 4 Way Connector # PK12716
