Great idea sorry you got a leak is ther a guide to doing this somewhere?Installed an E39 wiper stalk, wired and coded it so that the "S" button activates the headlamp washers. This way I can independently control when I need them instead of waiting 5 tries or whatever. Of course I've since discovered that my driver side headlamp washer is just leaking under the hood. Even the passenger side doesn't seem to be spraying as strongly as it should. That could just be because of the pressure loss on the driver side though
