good elec break away setup for older gooseneck

my old big tex gooseneck, 25' +6', dexter 10k HD axles with drums, doesn't have a breakaway system. i thought i might put one on. i am not a professional hauler or anything. what is best place to buy one? thanks!

 

Amazon has pretty much everything and if looked at correctly decent quality items.
