ok i bought a used kit off a buddy of mine. it's got everything i need. it's a NX wet set up. it came with a fuel pressure part that i guess reads the fuel pressure and if it senses a drop in fuel pressure it drops the nitrous so i won't spray under a lean condition. my question is how do i wire this into the set up. I've figured out that the way to go is from the battery through a fuse to the arming switch, to the wide open throttle switch and then to the siloniods(not sure on spelling for that). please some one tell me if i'm correct on this. i've looked at the diagram that is in the FAQ section. and i'm guessing that when i wire in the siloniods that i also wire in the fuel pressure part? so that it cuts the power to the silonoids? i don't mean to sound stupid here and i hope that i don't. trying to save me some money and i'm pretty mechanically inclined. thanks for the help

 

The fuel pressure safety switch simply provide a ground. You can hook it up to the ground on the nitrous solenoid, or the relay ground. Here is a diagram from nitrous express:



btw, nitrous express has installation instructions on their website. They are not maxima specific, but they will get you by.

 

thank you very much, that is exactly what i needed
