diode trick

You are getting back EMF from the coil, it is the magnetic feild colapsing so yes a diode inline at least on the main power wire to the switch box will help.

i dont have the speaker poping problem , cuz i dont have any amps , just a cd player , the problem i have is that when i " tap tap tap tap " the switches it triggers my windsheild wipers

if i wire the switch box to ground, how do the valves get power? run a wire from the battery to each valve and the wires from the switch bow to the ground on each valve? so it would be like a switched ground and not power?

exactly, it works the same either way.

Chris i had that same exact problem on a 96 s10. it doesnt make any sense but i had to tap off a different ignition wire to get it to stop.

a diode only allows 1 way current
