window wiper/ sprayer connection

[classic69]

i need to disable the wiper motor from turning on when you press the window washer switch (pull the lever toward yourself) because i set it up to spray on the intercooler and dont need the wipers from turning on every time i spray if anyone knows the best way to disable this please help

It's pretty pointless to spray the IC (cool air off-boost will be drawing off much more heat than ambient water on the outside of the IC), but since I realize you just won't believe that, find the wire in the column that grounds the wiper motor relay and disconnect it.
Try to do it in an easily-reversible way so you can correct your error later.

well i have my intercooler top mounted next to the throttle body horizontally ( i was bored ) in a way where i can spray half an inch of water on it so it actually works pretty good but the wipers are annoying the shit out of me but yea ill take the column apart and try to find that ground wire
