MSD rpm-activated window switches allows you to take control of your nitrous. You can activate and deactivate circuits at pre-programmed rpm "windows" and they are especially useful for nitrous equipped engines, because the nitrous system can be shut down just before the engine's high-rev limit. They include a ground to activate a circuit, and can handle up to 1.5 amps.

These MSD 2-step rev controllers coupled with MSD's digital 6AL ignition box let you choose from two different rpm limits that can be activated at different times. For example, you can use a lower-rpm setting for staging and then automatically switch to a higher-rpm setting after you release your trans-brake or line lock. The 2-Step is also digitally controlled and connects to the Digital 6AL's gray tach output wire. There are two easy to read rotary dials that let you set the launch rpm in 100 rpm increments from 2,000-11,800 rpm. There is an activation wire that connects to the transbrake, a clutch switch or to the line-lock to activate the low rpm limit. When that switch is released, the low rpm limit is turned off and the car launches hard!

MSD shift lights have a built-in rpm sensing circuit that will turn the light on when the engine reaches the desired rpm. The rpm is chosen with MSD plug-in modules. They feature a bright cluster of LEDs, making them easily visible, even in broad daylight. The lights also turn on for a second or two when the ignition switch is first turned on, to inform you that they're functioning properly. The Shift Lights will work on 2, 4, 6, or 8-cylinder engines. They plug directly into the tach output on MSD 6, SCI, 7, 8, and 10 Series ignitions, or can be connected to the negative coil terminal when used with points or inductive-type ignitions.

MSD compact LED shift lights feature a small design that fits neatly onto a steering column or on top of a dashboard, without blocking your line of sight. Their bright LED will alert you to shift at your desired rpm point without being obtrusive, but will illuminate bright enough to be easily seen in the daylight. They plug directly into MSD's line of Programmable Digital Ignition Controls via two wires, or they can be used with factory or other aftermarket ignition systems through an rpm-activated switch.

MSD automatic coil selectors are quick and easy way to switch from your primary ignition to your backup! Running two ignition systems gives you peace of mind during a long race, but how do you swap the coil wire to the back-up ignition? With MSD, that's how! They have two posts that connect to the voltage towers of the coils, while a third post connects to the distributor. When you switch to the back-up ignition, the coil selectors sense which coil is being fired and then transfer that coil's voltage to the distributor cap.
