OT - F350 Aux Power Stays ON

I've got an 06 F350 Super Duty Lariat in the shop. The aux power to the radio, windows, and whatever else that circuit powers, stays on even after the door is opened and the ignition off. I looked on some of the Ford sites, didn't find an answer...

I pulled relay 306 and everything went off. Plug it back in, feel it click and everything comes back on. Switched it with another relay, same problem. Disconnected the ignition switch, still stayed on.

I'm thinking there is a timer that controls the relay, supposed to turn it off after 20 min or so. That doesn't happen either, it will stay on indefinitely. Anyone know where that timer is? Any other ideas?

Thanks!
