2.11 Electrical System Installation
Use the following procedure and refer to Figure 8 for the electrical system installation.
WARNING! Death or injury may occur from working on a charged electrical system.

O System
1. Disconnect the car battery at the ground cable (if not already done).
WARNING! Binding or dragging of the throttle linkage will create a potentially dangerous stuck-throttle condition.
Ensure that the microswitch does not interfere with normal throttle linkage operation.
2. Install the throttle microswitch (31) on the throttle body, so the microswitch is triggered by the throttle linkage at wide-open
throttle only. Figure 9 shows the suggested mounting configuration.
HINT:
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 the application.
A. Mount the throttle microswitch on the intake manifold so that the throttle linkage movement triggers the microswitch.
B. Adjust the microswitch to trigger at wide-open throttle by adjusting the microswitch’s position to ensure the actuation
arm of the microswitch “clicks” at the same point your throttle linkage reaches wide-open throttle against the throttle
stop (Position 10A).
C. Ensure that the throttle and switch can reach the activation position by using the accelerator pedal: Slowly press the
throttle to the floor while you listen for the “click” of the microswitch (Position 10B).
