To revise the possible workings with a steeda, modify the setup to be a magnetic switch. mount the switch on the outer edge of the interior (bottom right, where the bottom of the shifter would be in first) and place a two wire powered coil (they are TINY) on the shifter itself. Whenever you go in to 1st, it will pull the mag.switch open and kill the setup.
That would fit in most any space.
