FPSS INSTALL and Q's

[pgriffith]

Just installed the NX FPSS. It was a breeze. Ok so the hole purpose of this is to cut the nitrous if the fuel drops lower than 35 PSI right?

So does it work when and if I were to hit my rev limiter?

[pgriffith]

and how does this work exactly? It doesnt make sense to me. It just has a ground wire and a power wire that goes to the relay. So how does it turn off the nitrous?

I don't know how it works electrically because I don't wire anything.
If the fuel psi drops then nitrous is cut off.
I would assume that there is some kind of pressure switch in there.
