Availability of Trailer Wiring Adapter from Vehicle 7-Pin to Trailer 7-Blade with Coiled Wire

Question:

My tow vehicle to trailer wiring needs replacement. I have a CMV with a 7 pin round connector and the trailer has a 7 blade round connector. Is it possible to get a 10foot coiled cable with a 7 pin round connector on the vehicle end and no connector on the other end?

I have a coiled wiring connector that may work for you, but we do not carry a 10 foot long coiled cable that has a 7-Pin round connector on the vehicle end. We also do not carry a 7-wire coiled cable that has exposed wires on each end.

The closest product to what you are looking for is the WesBarg 7-Way, RV-Style Connector with 12 Foot Long Coiled Cable, Trailer End # WG54006-046. This wiring and connector offers a coiled cable that will extend up to 12 feet. One end of the wiring provides a trailer-end 7-Way blade style connector, while the other end has wire leads to allow you to wire in the connector of your choosing.

If you do not need the 7-Way blade style connector that is already installed on the # WG54006-046, you can cut the connector off to install whatever style connector you need. Since we do not specialize is commercial towing, wiring your own adapter will likely be your best option to provide the correct connectors with the correct functions for you. I have attached a review video of this connector for you.

I have also attached a link to the product page for all of our trailer-end and vehicle-end connectors for you. For a connector that will fit the 7-Pin socket on your commercial vehicle, you can use the Pollak Heavy-Duty 7-Pole round Pin # PK11700. To connect to the 7-Way blade connector on the trailer, you can use a vehicle end socket like # PK12-707E.
