Anyone know where I can hook up a pressure switch to turn the washer motor on? I've got an IC sprayer setup. Wipers are disconnected (RainX). I'd like to be able to use the stalk switch as well as have the boost switch work. I'll be posting some IC temperature results soon.

 

Any problem if I just connect the hot lead off the motor to the battery through the pressure switch ?

 

thats exactly what you should do. unless the motor is switched ground which many things on the rx7 are. some simple testing will reveal the correct wire.
