RPM Digital Actived Window Switch for Shift Light or NOS Solenoid MSD

Description

New MSD RPM activated window.  This is basically a relay, and when you reach two preset RPM's that you have determined, the switch will activate and deactivate a ground.  Adjustment for RPM is done by digital and pushing a button (no pills).  As an example, if you set the lower RPM to 3000 RPM and the upper RPM limit to 6000 RPM, the unit will ground as long as the engine RPM is 3000 RPM to 6000 RPM.  1.5 Amps max.  For applications of current over 2.5 Amps, you would use a relay (not included).  This can be used to control an additional fuel pump, stage of nitrous, dash light, timing retard, etc.  Attaches to tachometer lead.
