MICROSWITCH INSTALLATION
NOTE:
The microswitch may be mounted to the bracket in a variety of positions and on either side of the bracket. The bracket
may be bent to suit your application.
1. Disconnect the battery.
2. Mount the throttle microswitch on the intake manifold, so the throttle linkage movement triggers the microswitch.
3. Adjust the microswitch to trigger at wide-open throttle by adjusting the microswitch’s position to ensure the actuation arm of
microswitch “clicks” at the same point your throttle linkage reaches wide-open throttle against the throttle stop (Position A).
4. Ensure that the microswitch is activated by the accelerator pedal: Slowly press the throttle to the floor while you listen for
the “click” of the microswitch (Position B).
5. Install the NOS arming toggle switch in the vehicle’s interior, within easy reach of the driver.
6. Install the Wiring Relay with the Harness attached, in the engine compartment near the battery. The Relay’s orange wire
should reach the positive (+) battery terminal.
7. Connect the orange relay wire to the positive (+) battery terminal.
8. Connect one wire from each solenoid together. Join the solenoid wires to the blue relay wire.
9. Connect the remaining first solenoid wire to the ground.
10. Connect the open second solenoid wire to either terminal on the fuel pressure switch.
11. Connect the open terminal on the fuel pressure switch to the ground.
12. Connect the green relay wire to either terminal on the microswitch.
13. Connect the open terminal on the microswitch to the ground.
14. Connect the red relay wire to the middle (#2) terminal on the arming toggle switch.
15. Connect the (#1) terminal on the arming toggle switch to the switched 12-volt power source.
16. Connect the (#3) terminal of the arming toggle switch to the ground.
17. Reconnect the battery.
