    Features & Details

    • Perfect for Nitrous System Control
    • Programmable from 200 Rpm to 15,000 Rpm in 100 Rpm Increments
    • Accepts Different Inputs Signals
    • Can Be Used with an Input Voltage of 9 to 18 Volts
    • Fits All 1996 to 2014 Mustangs
    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.

    Am I able to run this msd window switch along with a msd 2 step that I have?

    1, on a 12 gt where does the signal wire hook up to the car ? 2. What is the life expectancy of this unit being on most of the time ? Chuck

    • When installing the MSD Digital Window Switch on a distributorless ignition, such as that found on your 2012 GT, you will require a tach adaptor to get a valid RPM signal, such as the one linked below:

    Will this work with a N2MB wot box?

    • Unfortunately, we have not confirmed the use of this MSD Digital Window Switch with an N2MB Wide-Open-Throttle Box.

    Can this be set up to start spraying in a selected gear? i've seen some window switches have the ability to start spraying in a selected gear, does this window switch have that ability?

    • The MSD Digital Window Switch will only control the Nitrous in the RPM range across all of your gears at your desired throttle position.

      Excellent Digital Window Switch

      As Advertised

      This MSD Digital Window Switch works exactly as advertised. It can be a little tricky to install so label your wires to avoid possible confusion.

      MSD Switch

      I was manually flipping on and arming the nitrous system at 3k. I have an automatic GT with 3:73 gears and I know, I was not always consistant. I knew I could remove the variable of hitting the nitrous arming switch late by buying the MSD unit. My first run I went from a Xx.77 to a Xx.61. Definitely purchase!!

      MSD Digital Window Switch

      Window switch works great! I installed it on my 2014 mustang gt with no problems. The only downside to this window switch is it's kinda big, but overall I'm very happy with it and I recommend it to anyone who wants to be extra safe while using a nitrous system in there mustang! The digital screen is a plus!

      A must have for Nitrous

      The MSD window switch easily allows you to turn your spray on and off at the touch of a button. I have my MSD Window switch controlling ground on my arming system and set to provide ground from 2500-6500 RPM. Easy to install, easy to set and change preferences. American Muscle sells this part 5 - 10 dollars cheaper than anywhere else!
