I'm sure many of you have already done this but I've just rewired my wipers for 2 speed and self-park.
It was a bit fiddly but pretty straightforward. I'm somewhat surprised that Kirkham don't wire the motor up "correctly" in the first place, all that's needed is the correct switch and a couple of extra wires. Having said that, I guess it leaves us something to do to "improve" our cars.
