I have a Mk1 car & getting a Mk2 Cooper S wiring harness.
The wiper for the car at present is single speed & r/h park. It works, connected pin 2 & 3 to a battery.
Looking at the wiring diagrams, both Mk1 & Mk2 have single speed & 3 wires to the wiper motor.

Do they return to the park position when the switch is selected off?
Should I get the wiring for 2 speed wipers added, just in case I put in a 2 speed wiper later?
Are 2 speed wipers better?
Any difference with motor size, shape?
Do they attach to same wiper rods?

Mk1 and Mk2 wiper motors (sq vs round) have a different rack travel, and different wheelboxes to suit.
Also the motor mounting holes on panel are different.
Yes they do park when turned off.

If you fit a round motor to the old square motor's rack, the wiper arms will swing 180° = too much. Need to swap the wheelboxes too.
Last Mk2s and Police ones had the 2 speed Clubby motor, there is a thread here with the right wiring and switch details.
see http://www.ausmini.com/forums/viewtopic ... peed+wiper

In your case I would add an extra wire, long enough to go from the motor to switch- but leave it disconnected for now.

Here's the wiring in mine now, with 2 speed Clubby motor. Switch is MGB one.

Heritage MG stocks them.
The toggle on it looks similar to a Mini one, but it has less angular movement between the positions. ie when up (off) it sits a little lower than your headlight switch does.

does it matter that the mini with the square wiper motor parks on the opposite side?

You can make the round motor (1 or 2 speed) park on RH side simply by turning the drive pin plate 180° on the plastic gear.
I tried this and it works. :wink:

If easier for you I can show you how to make the square motor have 2 speeds (or variable speed), PM me for details.
