Nitrous with a 4spd

Just curious as to how you guys out there configure your NOS with a Manual Transmission.

Not that I will Immediately be using it but the information is always useful.....

I am using a Digital 6 Ignition that has the ability to lock it out at lauch via a wire for the line lock and a retard once it is activated. Do you guys just have a button on the shifter? Activated at full throttle and a momentary switch to cut it off on the clutch?? The digital 6 has a 2 stage rev limiter also 1 for launch and on top.......

Anybody's input would be greatly appreciated.
