Nitrous Wiring help
What can i use for a replacement relay? just any normal 30 amp relay from advanced? I have installed one nitrous system in my mustang years ago but it came with all directions and color cordinated everything. Now im kinda on my own. Ive been looking at alot of diagrams tonight but i was hoping some genius could tell me how to wire all this together or if there is a straight up diagram on how to wire up the wide open throttle switch with the msd window switch i know the window switch runs to pin #35 for tach signal and it needs to be in 4cyl mode to work correctly. I dont have a Fpss and most diagrams seem to have them. so wiring gurus can you point me into a good diagram that is easy to understand that integrates the msd window switch and wot switch to the relays with the universal nos wet kit and also where do i integrate the bottle warmer in all this? Thanks a lot guys.

Typical relay diagram. I would choose a good brand like Tyco if you can find one.
Voltage and ground across 85 & 86 (polarity doesn't matter) to control the relay.
Apply 12v to 87 and when you put voltage across 85/86, you'll get voltage out on 30
Not sure if your window switch will allow for it, but i grabbed my TPS and tach signal off the rear of the passenger side harness that runs along the fuel rail. You can grab signal for one coil and program it accordingly and get your TPS signal there too. My FJO advises to use the falling TPS voltage, but there are both in that harness if you need the rising.
