2 –GP15K Diode

Normally Closed: GM Heavy Duty Ignition Controls do not have a White wire input so this Switch must

be run in a Normally Closed position on the small Red wire. This is the 12 volt On/Off

wire for the Ignition. When the button is pressed, the Red wire will be opened shutting

off the ignition. See Figure 2.

Normally Open: It is recommended to run the Switch in a Normally Open position. The Switch will be

wired into the White wire of the MSD Ignition and to ground. When the button is pressed, the White

wire will be grounded, killing the ignition. See Figure 1.

Note: A GP15K diode must be in line on each white wire before the switch. If the diode is not installed damage

to the ignitions will occur. The diode must be installed with the stripe (or band) towards the kill switch.
