I have bought some genuine sti spray nozzles and a pressure relay so that the system only activates at 1 bar of boost. But I am not sure what sti interior IC spray switch I need - is there only one type - ie push to turn on and push to turn off?

Also, how do I wire this to the pressure switch and motor as I understand there are four or five wires on the sti switch not just one?

any help is much appreciated,

cheers
