ive always wanted to run ground switches at the gear levers so it only activates if the trans finds the gears..if it doesnt engauge it doesnt activate the nitrous..
with only the clutch switch if you release the clutch with a missed shift you will be boosting the motor with no load on it....shaAWING...
however i run an auto...

I had nitrous on my old mustang that was a stick car. It was on a wot switch with no other protection besides the msd rev limiter. If I missed a gear it didn't do anything stupid surprisingly. It would just dump a HUGE plume of black smoke lol. I sure wouldnt risk it without a rev limiter.

ok let me clarify.
you run a wot switch at the carb..
but you isolate the selinoid (it grounds through its mount)the grounds run through switches on the shifter or shifter linkage..so the only way the selinoid goes live is if your engaged in gear..
the only button you would need is on off..located anywhere you want it...

So you dump the clutch, the N20 is activated ? must have a another switch somewhere. What happens when you let up on the gas when the N20 is still activated? Sounds like a bad idea to me. 
WOT switch, so unless im at wide open throttle there is no nitrous activated....its really simple actually, just a couple of relays, but i would have to post the drawings. Two position toggle switch with 3 prongs- one position is line lock only, second position is the two step and nitrous (when the nitrous switch is activated). Hold down the button on my shifter for the two step as usual, and once I let go of the button when I dump the clutch the nitrous will be activated as long as I am at WOT...so no WOT, no nitrous

the trick with the manual transmission is if you miss a shift...and you mash wot...you will have no2 with motor unloaded...
having the circuit interrupted if the trans is not engaged into a gear..is the protection your after.
the no2 solenoid activates by grounding...
interupt the ground and it is dead..
on off switch arms dis arms the system.
wot switch activates the no2 solenoid.
ground switches on all four forward gears completes the circuit...alowing wot switch to function or be over ridden if its not in gear...

What about running an rpm window switch? (MSD)
That's what I ran on the nitrous system on my 97 Viper.
It doesn't come on until it hits a preset rpm and shuts the system off at a preset rpm (below the rev limiter rpm).
The main power switch was by the shifter.
Kayse can't keep up at all now. lol

Wot switch hooked in with 2step and line lock. I would use a window switch to have the nos shut off a few under rpms below rev limiter.The best way would be to wire off all foward gears on the shifter so that is the only time it is on but thats not the eastiest way.You really do not want the motor on the high side chip while on the spray it becomes very hard on parts. On my buddies 8.5 nos car we use a wot switch hooked in with the trans brake and 2 step to a elderbrock nos controller to leave at determined of nos amout at the hit so it makes it a little easy to leave on.Here's a pic from yesterday.

 Yes, Todd is unfortunately right...But, I have the car all wired up already for the nitrous from this past summer with the 4 speed, so I did figure it all out...thanks though
