What is a tempo controller?

[Roundabout-Now]

I\'ve just been looking in the boot of my car and have found a little black box marked as "Electronic Tempo Controller" with a rotating control (min-max).

Its power wires aren\'t connected, but there are wires running of into either side of the car.

Any idea what it is? I\'m being lazy and don\'t want to pull all the panels to find out where they go.

just a guess but the rear wiper speed controller...

Not sure about that. It doesn\'t look like a standard item and it sends wires to both sides of the car which makes me think it wouldn\'t be for the single rear wiper.

indicators?

Could be. I\'m getting tempted to tear off the panels tonight and have a look now.
