I"m glad they put the 7-pin in. Makes it easier to install a trailer brake controller if you ever do decide to tow a trailer large enough to have brakes. All you need to do is run the blue wire back from the brake controller to the plug. Heck, it's possible the blue brake wire is already routed forward to the engine bay. Maybe they've even put a port in so you don't even really have to wire in the controller, it just plugs in with the right adapter. BTW, pretty much every single mid-size truck comes this way. They're not equipped with brake controllers, but they're more often than not wired for them, c/w 7-pin connectors.
Since when is making a vehicle MORE capable ever a bad thing? Good for Hyundai for actually doing their research and recognizing what people who tow may want/need. In this case a 7-pin connector.
BTW, provincial rules vary, but the rule of thumb is if a trailer has a gross weight of more than 1500lbs, it needs brakes. My 10' pop-up has brakes, and I would consider it easily towable by something like the Santa Cruz.
