Wiper wiring for the first of the Lucas Australia single speed round motors introduced in 68 is bit of a mystery. The wiring diagram posted is for the original square bodied DR3A? motor. This is the one with the right parking wipers.
The Lucas Australia wipers park on the left. The motor is a 12AUW type and comes in single and dual speed versions. It uses regenerative braking to park the wipers. The DR3A type doesn't so the wiring is different.
There is no wiring diagram in the manual that I know of that has the correct colours for the late Mini Deluxe and MK1.5 Cooper S.
If you use a Mini K wiring diagram the wire connections are correct but I think the colours are different? which makes it a bit awkward to sort things out but it can be done.
The wiper switch is different to the original DR3A motor as well. The single and dual speed round motors I think also use different switches to each other but I'm not sure.
You may be able to sort it out by trial and error. There is a supply wire direct to the motor from the voltage stabilizer (there is a common input terminal at the stabilizer which also supplies the wiper - the wiper is not supplied from the output side of the stabilizer) so if you can find a common coloured wire at the stabilizer and the motor then that is the main battery supply to the motor. The motor has 12V applied all the time the ignition is on. The other 2 wires go to the switch.
I've been looking to upgrade to the 2 speed motor but haven't worked it all out yet.
When I get a chance I will check the wire colours and connections but it will not be for a few days.
