Right now I have a switch wired in that lets me engage my meth kit or turn it off. Its wired in as follows.
This allows me to turn off the kit when I don want to use it, good for tuning and seeing if the meth is working.
But now, I want to power the pump myself w/o getting out of the car and running the power wire to the battery.
How would I wire in another switch to turn the pump on while Im at idle.
The reason for this is because when I went to the track no meth was running because air got into the lines from refilling my tank. So I want to "purge" so I can watch the A/F dip at idle, that way I know its primed and ready to go.
Adding a momentary push button switch that would bypass the boost switch would do the trick, no? This way, the "prime" switch would only work when the system is ON.
I wouldn't wire a switch from the battery since you risk that your system inject all the liquid from the tank in your cold side pipe in case of switch failure. That would be bad.

This is exactly what I was thinking, a push button when the toggle is "ON".
buy this... Momentary Contact Switch
and connect one terminal of the switch to the terminal labeled 85 on the relay and then connect the other terminal of the switch to ground. essentially you are doing the job of the pressure switch.

Im gunna pick that up at radio shack tomorrow and give it a try.
do it how i said above, its safer to just complete a ground
Indeed. The best way to do this would be to add the switch to the ground that activate the relay, like TheFace told you. You're better doing this than connecting a switch on the hot wire of the pump. Anyway, by doing this and using enough wire, you'll be able to put the switch in your console beside your arm/disarm switch.
If you do this at idle will it cause the engine to bog down or foul plugs? I had my pressure switch set at too low of a psi and when I got a tiny little ptb it bogged down really bad, and ran rough for a minute. Just wondering. I thought about doing this also but I am running two M5 nozzles and thought I would drown my motor.

Well If you wanted to get really fancy you could run 2 solenoids with a Y in-line which splits to 2 nozzles.. Press the button it will prime the pump and open the dump solenoid but not the main solenoid.. Then your primed all the way to the solenoid. When the pump is triggered normally it opens the primary but not the dump.. This would solve your purge.. Very much like a NOS setup. Cost is a bit but if you want it done right.. Its how I would do it.
