Mk 2 wiper motor...

[sandman]

Could any one explain to me how the 3 connectors on the Mk 2 wiper motor is wired and what they do?

If I want to just use one [positive] wire to control the wipers like on the Mk1 - is this possible? How should it be wired?

(in case you wonder - this is for a racecar, so wiper parking is no that important)
