Clutch input (gray wire), if you have a 99 or newer, you can tap directly into pin 32 on the BLUE PCM connector.
Nitrous (yellow wire) provides a ground when the 2 step is active. Connect this one to terminal 85 of a standard automotive relay. Terminal 86 of the relay goes to 12V, either constant or fed by your nitrous arming 12V supply. Splice that relay into your nitrous system. Terminals 30 and 87a will be connected when the 2 step is off. Use these terminals in something like your WOT switch, FPPS, or window switch circuit.
I can draw it up if you need more clarification.
