I think I found something on the 5 pin stock STI switch on the internet, but when I went to install the switch and the tank I can't get the switch to turn OFF the water. This is how I ran it (or tried to) I have the power coming from the pump in the back (pink wire ?) to the Manual trigger / power on the switch (pin1) top left. I have (pin2) going to fuse#9 (radio). Another wire from the pump (black wire) grounded in the back on a bolt, then from there to the switch (illumination ground) then grounded to another bolt under the dash. I get power, I get water coming out continuously....(will not stop) even if I depress the switch and let it run for 5 seconds..... so on and so forth. Nothing. Is the switch fried ? I can't even get the illumination to come on. I need help guys. I don't want to use an aftermarket switch, I want to keep it as stock as possible on the inside.
