      Yes, the plug goes into the rev limiter chip hole(s). Basically, this gives you two rev limiters. One is on all the time & when power is sent to the 2-step, it changes your rev limiter to the 2nd chip on the 2-step. It's mainly used when drag racing & can be wired into a stand-alone switch or into a trans brake switch. It will allow you to floor the pedal at the starting line (with the 2-step activated) & hold the engine at your "launch rpm" until you let go of the button.

      I have a MSD 2-step which I haven't installed yet. I'm planning to wire it together with my line-lock (4-speed car).
