That looks like a neat setup! It could probably be used to set up a headlight nozzle using the Aux switch!
I've also seen folks simply install longer hoses from the washer tank to the nozzles and they make a few wraps around the upper radiator hose. Once the coolant warms up, which is very rapidly, it gets the washer fluid coming out of the nozzles very hot. In fact, some have said it was so hot they had to reduce the number of times it coiled around the upper hose to cool it off a bit.
