For instance, let's consider a drag car equipped with a Three-Step Module Selector inserted into the rpm socket of a 7AL-2 Ignition. The diverse rpm modules activate when 12 volts are applied to their respective wires. Connecting one wire to the line-lock circuit engages a module during the burnout, ensuring consistent tire temperatures. Releasing the line-lock button deactivates this limit. On the starting line, the second limit can be triggered through the clutch or trans switch, ensuring a steady rpm for consistent holeshots. When no modules are selected, the remaining high limit safeguards the engine in case of driveline failure.

The Module Selectors are also compatible with an MSD Timing Control. When plugged into a retard module socket, they enable the activation of different retard amounts at specific times. This is particularly beneficial for engines upgrading to a multi-stage nitrous system. With an RPM Activated Switch, the Two Step can be used to trigger a shift light at different rpm. It's important to note that the Module Selectors must be used with an MSD Soft Touch Rev Control or a Timing Controller featuring a high-speed retard module. No rpm or retard modules are included.
