hi, was wondering about the windscreen washer squirt buttons. primarily the foot pump operated button that screws to the floor. does anyone make a repro of these? i bought a basic washer pump kit i was planning on installing instead of the foot pump if theyre not available. was thinking of mounting a second dimmer switch where the foot pump usually goes & wiring it up to a pump connected to the washer bottle. to feed the switch can i run a wire off the relay switch or is there a better place to wire it up to. hope this makes sense, richard.
