Rheostat level: Notes
The main instrument unit uses the rheostat value to control the following instrument lighting:
- Speedometer
- Turbo gauge
- Tachometer
- Coolant temperature gauge
- Fuel gauge
- Selector lever indicator (automatic transmission)
With the main lighting turned off and fuse 15 for the daylight driving lights removed, the SID unit sends out Rheostat value 0% on the bus.
