Notes:	30 is unswitched battery. 15 is live for "on" and "start". 15A is live for "on" only.
	All 4 injectors in parallel. Live side of injectors go to 15 via F7 (30A).
	For unleaded, O2 sensor is a non-heated device with one connection (other connection is GND) For leaded, O2 is heated, and an additional potentiometer is wired between A11 and B8, with the wiper going to B11
	X45 is the octane selector. X45.2 is connected to GND (wire: B0.5)
	INST A10 is connected to E35, "SES" indicator INST A16 is connected to H8, speedometer
