On the dashboard is a little warning light on the left hand side of the steering wheel. It has two wires. One (blue) has fallen off and can go either side of the other wire. Looking at it from the dashboard side, which terminal does it go on? Left or right, oh yes and what does it do? Its on a 74 Kombi.

Is this the Brake warning light on the dash face to the left of the fuel gauge cluster?
Or is it in the fuel gauge cluster?
