2 step w/ clutch switch Does ant body have any good wiring diagrams which show how to use a 2 step and a WOT switch. that activates (a launch rev limit)when the clutch is depressed to the floor and cut the nitrous.And when the clutch is released the nitrous engauges.TIA Brian

send me your drawing on your 2 step, and I will return a clean easy to understand layout for you. Sorry I do not have one at this time, but am willing to draw.

I don't have a schematic, but all I did was add relay in-line with the WOT switch wire. The relay is energized to open contacts when the 2-step is activated, and the relay is de-energized and closed contacts when the 2-step is deactivated. There's a wire on the 2-step that's specifically for a relay, and that's the one I used. Forget which color it is tho. 
Works fine for me.

Thanks gentelmen,
Ricky I am not well educated w/ sending diagrams in email format,however I can fax it.I am using a MSD 8739.My biggest fear is that something will malfunction or I well set the 2 step every time I shift.Thanks again! Brian.

Gray wire to the clutch switch, Blue PCM connector pin 32 (gray wire on the harness)
White wire to a momentary pushbutton switch, other side of switch to ground
a typical automotive relay, you need one that has 5 terminals, not 4.
yellow wire to terminal 85, 12V to terminal 86. Intercept your power feed or WOT switch arming for the system. Basically cut that circuit, and splice in the relay using terminals 30 and 87a. When the 2 step activates, the relay should open and disconnect the 30 and 87a terminals. Those are the normally closed connections of the relay
Depending on how you wire it, you can use 87 to run a light or something if you have 12v on terminal 30.

BTW, my issues was a faulty circuit inside the 2 step. The wiring process is correct.

Its the one closest to the windsheild.... just remove the connector and look at the color of the plastic in the center.

Sorry for being so dumb about this, I guess I need a picture to understand it.
you got it.
