That device is called an idle speed boost valve.  On 85's you will
have one for power steering and possibly one for A/C (if equipped).

Their job is to increase idle speed when power steering is turned
hard right or hard left or A/C compressor is engaged.  They don't
really do anything when driving at normal speeds, just for idling.

If it is a brown wire it should be connected to ground.  Brown is
generally ground in VW land.
