H&S doesn't shut off with key.

Installed a mini max on a 2010 6.4 and all went good but it stays powered on, what am I doing wrong? I tapped the aux power into the fuse box on the pass side but I unplugged that and it still stays on.

I got it, gotta hook into ignition power and turn the switch on the OBD port off. I gotta say this sucker runs! Very quiet and refined too.
