Could you have a system set up only to spray when you hit the button? Lets says I get a WOT switch but I'm street driving and some ricer wants to race so off we go and I'm already whupping him then at WOT/rpm range my n20 comes on and I totally destroy him. I don't want to spray unless I want/need to. Try and keep it a secret, hehehe. So could I incorparate a button I can push to activate the n20 only when I want to along with a WOT swicth so I don't accidential hit the button and blow my motor?

yes, just install all the switches in series, so they all need to be on for the system to spray.

I did an install like this.

ARM---WOT---selector (a)---relay ---- MSD window-- ground

On the other selector switch side (b) it was like this

ARM --- WOT--- Selector --- Button--- Relay --- MSD window --ground.

So you had a choice, either just WOT, ARM, and Window range and you were spraying.

Or you could do WOT, Window, ARm, and Button on to spray.

But also remember, you will have a master arm switch, so you dont need to turn the system on if all your looking to do is be able to race ricers off the bottle.
