Its right there at the bottom of the page. Best bet is add it to your sig so it always comes up although if you have a lot of MBs that could still be a problem.
With this car there is a vac/pressure pump in the trunk and depending what way you turn the key in the drivers door it tells the pump to produce vac or pressure. The pump has one ground wire and two power wires. If you lock the doors the first wire has power and the other does not, if you unlock the doors it is the opposite.
