A/T Gear Position Indicator
With ignition in RUN or START position, voltage is supplied to A/T gear position indicator, located on instrument panel. See Figure . When shift lever is moved to designated gear position, A/T gear position switch completes the ground circuit for A/T gear position indicator on instrument panel. The light on A/T gear position indicator will be illuminated to indicate the shift lever gear position. The A/T gear position switch is located on passenger's side of shift lever. See Figure .
When headlights are turned on, voltage is supplied to Red/Black wire at A/T gear position indicator. This changes brightness control from fixed setting to control by the dash light dimmer input on the Red wire.
