Perfect For Nitrous Systems. A MSD Digital RPM Window Switch will give you more control of your Mustang's nitrous system to ensure it is activating at the correct preset RPMs. While optional, a Digital RPM Window Switch should be standard on all nitrous installations for safe operation.
Programmable. The MSD Digital RPM Window Switch's activation points or "windows" are easily programmed by simply scrolling through the LED display to your desired rpm amounts. It can be programmed from 200 rpm to 15,000 rpm in 100 rpm increments with no rpm module required.
Inputs Signals. The MSD Digital RPM Window Switch is designed to accept an input rpm signal from a coil negative terminal (for stock ignitions), a tach output from an ignition control, an ECU tach output or even a 5 volt tach signal, making it one of the most versatile Digital RPM Window Switches available.
Application. The MSD Digital RPM Window Switch is designed to be compatible with all 1996-2014 Ford Mustangs, including the V6, GT, Bullitt, Mach 1, SVT Cobra, BOSS and Shelby GT500 models.
