Default Msd digital window switch

I am installing a msd digital window switch on my camaro with a nx kit. I know where 3 of the 5 wires hook up to. I know where Black goes- Ground. Red- Switch 12volt. White- Tach signal on ecu.


There are 2 wires where i dont know where to wire them into.

Grey- Normally closed switch output.
Yellow Normally open switch output

So where do the yellow and grey wire into on the nitrous kit.
thanks
Nate

Im not familiar with the msd switch, but does the yellow wire switch to ground during the rpm window? and if it can handle the current of relay coils, hook it up inline with your fpss, wot switch, etc which should all be connected to the ground of your relay coils (pin 85 or 86 on the relay)

I just had a question on the digital window switch, I just hooked mine up last week, works wonderful. I was reading a post on here that had said that u have to have the cyl set to four to read right. as it turns out this is true, my question, why? the instructions say one cyl. if you are tapped into the tach output wire by that time the analog signals from the cam or crank sensor, witchever the ecm uses to referece injector pulse and spark should have been filtered to a digital signal the ecm can read. Of course i have not done a ton of research on how the gen 3 system reads. just seems strange to me, but if it works, who cares.

chris also im not looking at my car right now and since you do a lot of wiring you might be able to answer this so i dont have to leave the a/c office

if you dont run a FPSS you just run the wire from the msd box to pin slot 85...but what if you dont run a FPSS or the window switch? what do you do with slot 85?
