The pin outs are there, you should take the connector apart; as the diagram in the book is from the back side and the connector is fragile.
basic LH2.2 function:
injectors should always have 12volts
LH2.2 gets tach signal from dist.
triggers/pulses various amount of ground to injectors
Check for spark?
Check for tach signal at LH?
Check for voltage at injectors?
Check wiring harness for shorts to ground?
Check for pulse at injectors when starting?
YOU really need the Bentley's manual and a digital volt meter. Any specific questions just ask.
