New to Nitrous
Not to be a dick, but you need to go to each of the forums that you have questions about and just read. The FAQs at the top of each will answer most of the questions that you just posted..
Nitrous... most, if not all of the nitrous users on the board use a window switch. You arm the system and thats it.

Once your rpms drop below 3000 the car won't spray anymore.
