Arming Switch and Installation

The arming switch is a red, lighted switch that is a “MASTER” arming switch for your nitrous system. Without it, your
nitrous system would be “on” all of the time and capable of engaging anytime you go to wide-open throttle conditions with
your vehicle. The switch, when in the “armed” position, is well-lit. Therefore, it should be placed in an obvious position
well within the line of sight and easy reach of the driver. Please refer to the procedures below for the installation of the
arming switch:

1. Locate the final position of your arming switch.
2. Drill a .450” (approx. 29/64”) hole for the switch location.
3. Insert the switch from behind the mounting hole and secure with the switch nut.
4. Do not wire until all other mechanical components are in place. Please see the electrical system installation

instructions for further information.

Note:

There is a collar included with the switch for applications that require special spacing during installation.

Microswitch Installation and Wiring

The function of your microswitch is to enable your nitrous system. It should be installed so that the switch is forced closed
by coming in contact with the throttle linkage only at the wide open throttle position. The nitrous system must only
function at fully-loaded wide-open throttle.

MICROSWITCH SAFETY INFORMATION

1.

Do not

allow wiring from the microswitch to come in contact with heat sources on the intake manifold such as EGR

risers or passageways.

2.

Do not

run wires to the microswitch that can create interference with the operation of the throttle linkage.

3. The microswitch must be located in such a way as to be clear of the normal operation of the throttle linkage.
4.

Do not

directly expose the microswitch to liquids such as water or gasoline.

This is a picture of an un-modified and “ready to install” microswitch assembly. The microswitch
bracket has several mounting positions available for clocking of the switch. It also is of a universal
length and can be attached to several positions on and around the throttle body.
