j par I can see that you and yellow rose don't see eye to eye but he is right here. I will try to describe how I have my 2 step set up ( don't have the computer skills to make a drawing, sorry). What you need is a long arm nitrous micro switch( I used a nitrous switch because there suppose to be quicker) and a 5 prong 8961 relay, on the relay there are 5 numbered prongs( 30c, 85,86,87, and 87a ). Hook the 2 step up to the ignition box(I use MSD) hook black wire from 2 step to good ground, the red wire from 2 step goes to the #87 prong on relay. Now hook a jumper wire between the #87 prong and #85 prong okay now run a wire from #85 prong and T it into the wire from line lock button to the solenoid(this is the wire that activates the solenoid). Hook the#86 prong to ground, Hook the #30c prong to the micro switch and 12v power to other side of micro switch. Now I have 6" inches of travel in my clutch pedal, there is 2" of free play on top and my clutch starts grabbing about 2" from floor or higher depending on RPM. I set the micro switch to release at 1 1/2". Okay now you pull to the line, you push the line lock button( which is now the actuation switch and line lock)stage the car push clutch to floor(hold to floor) release line lock button hold throttle to floor dump clutch on third yellow. which opens micro switch which kills relay, all wiring is back to normal and you are on your way down the track with better reaction times and better 60' and more consistent 1/4 mile ET because you are leaving at the same RPM every time. Yes you will probably go more rounds once you get it dialed in.
