On my sti4 the rear wiper is either 'on' or 'off'. Has anyone changed this to 'intermittent' and 'off' (rather than 'intermittent' and 'on' which would be no good to man nor beast).
It should be an easy DIY fit, but what parts do I need - intermittent relay???

 

I fitted a kit from maplin electronics to an old mini years ago, they may still sell them as kits.
