[Alan Roehrich]

I had an MSD relay set up to work the three step and the line lock in the G/S car. If you held the line lock button, you were on the burnout chip. When you staged, the switch on the clutch pedal switched you to the starting line chip, and held the line lock engaged, so you didn't need to hold the line lock switch. When you released the clutch, that switched you to the high side chip for the run.
