Rallye Bob-

Another way, use a brake line pressure switch connected inline of your braking system with a TEE, they are two wire, begin with a 12 volt switch in the car to power wire once you prestage, arrow down /enter/enter on the tach, and leave. Removing your foot from the brake pedal will start the recording plus three seconds and you'll be set. If you decide to use a two step you can utilize the same circuit, however you would have to remember to shut the 12 volt switch off in the car to prevent the two step from energizing through the traps while braking, or install a long arm switch to interupt for hi gear.
