I have been messing about behind the fuse panel on my gti 16v 91 kr and have come across a green wire with a black spade connector not connected to anything and i cant see anywhere it could connect0 to i have traced the wire back to the control unit for idling stabilization box behind the center console. I have had a look in the back of the haynes but cant find the unit anywhere. has anybody got any ideas or is it just a spare connector
