Mark 8 IRS bags ?

[Mesjr]

Hi all. I'm almost done with a IRS swap , I was going to use a coil over shock but have decided to go with bags. Question I have is are the ride height indicators 12v ? Are the bags sylonid valves and components something I can just wire up bypassing the computer ? I'm guessing the indicators are just switches that open a valve that let's air in when its too low . If that's the case it should be " easy " . Input ?
