Trying to help a guy with a 4-speed car and wondering if you guys that race 4-speeds hook up a switch to your clutch pedal to activate the line lock and 2-step?

I'm thinking this would be how you staged and launched consistently???

Roll in, turn on the top bulb, creep in until you turn on the 2nd bulb, depress the clutch all the way to trigger the switch to activate the 2-step and line lock (mash the go pedal) and then when the 3rd yellow flashes, you side step the clutch with releases the line lock and motor goes wide open throttle and you get a view of the clouds...

I would also have a manual switch to activate the line lock for the burn out (may hook the hot directly and let either of the switched provide ground)

Or am I completely off track, if so let me know how you guys make it work? (keeping consistency in mind)
