Can anyone help me with wiring a fog light switch as my on/off switch for my 5177 kit? I've seen the wiring diagram, but I don't know how to make it work. Thanks for your help!

get a test light, find the + and -, should take 2 min total, probably longer than it took for a reply, lol

 

He's got it ... run a positive to the switch (accessory power, so it's only able to be turned on when you have the car on) ... leave the ground that is hooked up to the switch connected as is ... then instead of having the output of the switch being the fog lights, disconnect that and hook your nitrous system up to it.
