IMPORTANT: Read the instructions before attempting the installation
Parts Included:
1 - RPM Window Switch

NOTE: RPM Modules must be purchased separately.
The RPM Activate Window Switch can be connected to stock ignition systems or MSD
Ignitions. When using a capacitive discharge ignition such as an MSD, do not connect the
Switch to the coil negative terminal. Damage to the Switch will occur.
The Window Switch is capable of carrying 1.5 amps. If the circuit you are activating requires
more current, an NX Relay, PN 15515 (Relay & Pigtail) or 15526 (Relay only) must be used.
The RPM Window Switch has a circuit that activates a device by providing a ground path
at a desired rpm(Figure 1). The ground will be removed at a different rpm to deactivate the
device. If no rpm module is installed the device will remain activated as long as the rpm is
above the activation amount.
