Brown wire insulation is ground on all the German cars I've seen.
Does it use a sending unit for air pressure reading or does an intercooler or manifold vacuum hose attach to a fitting on the back?
One of the wires is probably faceplate illumination that comes on with the parking lights and another wire would be switched 12 volts.
