alpine ine s920hd need for brake and park

I just installed an Alpine INE-S920HD head unit in my 08 F450. The install looked pretty daunting but I'm mechanically and logically inclined and gave it a go. I used a idatalink Meastro and harness to make the install a little easier. Everything worked pretty well except it appears I need the parking brake and brake signal wired into the unit to get it to go into setup mode. I also can not get the favorites menu to work.  I intentionally did not wire these (at the time) because I did not think I needed them. I will take the unit out and wire in the two brake signals. Is there anything elese I should make sure I didn't overlook? Who would ever think I would need the brake signal wires to a car audio unit?

In addition, it there a way to override the need to connect these wires to the head unit? 

Look at the pivot point of the parking brake. There will be a single wire at that point. That is the parking brake wire. Connect the Alpine's Yellow/Blue to that wire. On the foot brake lever there will be a switch with 2 wires, one wire has 12 volts on it all the time. The other wire will have 12 volts only when the brake pedal is depressed. That is the wire you will connect the Alpine's Yellow/Black wire. The purpose of the brake wires is to cover Alpine's butt in case you are watching videos and someone gets hurt in an accident.
