Oil Loss Liquid Level Sensor Connections
5. Reconnect the oil loss liquid level sensor 24V supply to
power supply 1A2 connector J5, Pin 1; this is a red wire
(64A) and was previously connected to the starter
module J3 Pin 1.
Note: J3 or J4 Pin 1 on power supply 1A2 may also be
used for oil loss liquid level sensor connection.
