rmkrum over at airforums.com found these adapters to a very cool system called “EZ Connector ” that adapt your current 7-way umbilical connections to the EZConnector system making a strong magnetic link between your tow vehicle and trailer.
You could also completely replace your 7 way connectors, but this approach let’s you maintain the ability to use the standard 7 way connector if you ever need to. Very cool find rmkrum!
Below are links to the Amazon male and female adapters you would need!
