Or I have one drawn up for the MSD 6 box and 2 step.

I'm sure I could just substitute the correct wire on your diagram for the Mallory with the correct one out of the MSD... could you post or e-mail it to me?
Thanks!

I have a Harlan 2-step in my LS1 car. Love it. Don't have to worry about 'where' you're launching from. When my motor was cam only, I'd just bounce it off the rev limiter and dump the clutch. But since I raised my rev limiter, I typically have the 2-step set to ~6100 to launch (depending on if the track will hold it). Nothin' quite like a 6k+ RPM clutch dump on ET Drags with the nitrous activating when the 2-step disengages.

I would rather have it on a switch, like on the steering wheel or shifter.

FWIW
Window switch works like this: a device is set to come on at a pre determined rpm and cut off at another predetermined value when activated. The Mallory 685 box has all these built into them, I don't think the MSD Digital 6 does. That's why I said the 685 box is a better bang for the buck. 239 vs 309 at summit

Here is what a guy from CZ28.com posted:
I think I'm going to try this, unless someone finds something wrong with it.

I am going to try this tonight, I am going to set up 2 relays as shown with a momentary SPST as the (-) pulse and then pull off of the clutch switch for the fused +12v.
This way when you get to the line, you push in the clutch, hit the momentary (this activates the 2-step) and as soon as the clutch switch drops the input voltage, it can no longer be activated until both input conditions are met (clutch in and momentary pressed).

Digital 6 and the Mallory 685 boxes both get wired the same way, just different colored wires coming out of the boxes. I now have both boxes covered as far as the nitrous coming on after the 2 step kicks out. The 2 step gets held in until the clutch or brake pedal is let up, just like you stated, but I don't think the circuit you linked to would work. Try it and see. If it don't, give me a shout, I know mine does
