MSD Window Switch help!

[OneQuickV6]

Alright, I've searched this questions MANY times already to no avail, gotta try again. I a trying to finish my nitrous install, and need help with this switch. I read that it needs to be in a 2 cylinder setting for our cars...How do I do that? I know it can be done at home without sending it back to MSD for changes, just gotta find the guy who knows how. So if you have any ideas or experience on this, please post!

Also, which wire to tap into off the PCM for the tach wire? I searched, and nothing really was found. They say you have to get it here and there, and there, and.....I am sure there is one wire at the PCM that I need for it, but which one? Any help on either questions is greatly appreciated!!!!

I can't help you with nitrous but, I do know where the tach wire is. Your pcm has two big plugs right? Well the tach wire is on the top plug towards the right. It is a white wire and it is on pin 54. You should see 54 right above where the wire goes into the pcm. let me know if you can't find it.
