Note: This does not apply to the G4X Atom ECU or the G4X Monsoon based wire-in ECUs.

This wire supplies a regulated +8V to be used for the Crank Angle Sensor (CAS) if optical or hall sensors are being used. Do not use this wire to supply power for other devices. Care must be taken as some optical and hall sensors are designed to use a 5V supply and may be damaged if supplied with 8V. If a 5V supply is required then the '+5V Out' may be used.
