nitrous wire diagram

Does this look right if you are going to purge through the motor?

that the way i wired mine last year,but the problem is you can purge it with never arming the system.
a few times i pulled to the line,purged it and forgot to turn the system on.
that diagram is bypassing the on/off switch.
if i am wrong somone please chime in.

are you using a stand alone fuel system for the nitrous? or one pump to run everything?

 

[85notch]

I am running the separate fuel pump.

I don't like the separate switch for the fuel pump. you forget to turn it on once and you can cause all kinds of damage .

Stand alone fuel system and a fuel pressure safety switch and you will be ok, if you dont have fuel pressure the nos will not come on, so no worries about forgetting to turn it on, the switch comes preset at 5 1/2 psi if it drops below the 5 1/2 psi it will turn your nos off,They also have them for EFI, just giving you some idea's

i would just run 1 arming switch. no chance to make a human error. and to ensure your system is on you can either get a light up switch or a dummy light
