functional and a lot easier and simpler install than ive found thus far... maybe im wrong, but thru my searching haven't found one that went *quite* the route i chose... many other DIY sprayers require auxiliary tanks and pumps... i didnt care to spend that money soo, this is the route i chose, and am very satisfied considering i get the same product from the cheapest expense.
i went with the "backyard patio mist" setup... found at my local ACE hardware. bought a roll of small diameter tubing, a pack of 'T" splitters, pack of petcocks (or shutoff valves w/e) and pack of .5" spray tips... all in all totaling roughly 10$
made a 4 port piece that i just taped into the 45' back of the scoop area, and routed the line between the seal and hood..
i routed this line to a shutoff valve, then to a T splitter... i spliced the factory windshield spray line and attached one end to the T splitter, and the other end to another shutoff valve then to the T splitter.
with this setup, i utilize the factory windshield fluid reservoir and pump, and only have to turn the shutoff valves to circulate the fluid... as for the wipers coming on just yank the fuse *edit... same damn fuse for the washer fluid pump... currently figuring a way to interrupt the power lead to the wiper motor through a switch in the engine bay* .. not much of a pain, considering summers in southern oregon are 90s-100s and id seldom use the windshield wipers... its a budget way to go and leaves more possibilities for adding sprayers. thought id share, since its so cheap!
