It is always helpful to provide the year when asking these questions.
Assuming 1.9l with Digijet, the box is the idle speed stabilizer. There
are 2 versions, one green one black. They activate at different RPM.
When the idle goes below the set point (~750-green, 850 black), it
advances the ignition timing to increase the idle speed. When setting
idle or timing, it needs to be bypassed by removing the 2 connectors and
then plugging them together without the box.
