Did your engine come with any wire/wire harness? If you have the milky white plugs there OBD0, if you have the grey plugs there OBD1 and OBDII.

Correct...

OBDI will have two for the distributor, OBDII will have only one.

OBDII will have a (CKF) crank fluctuation (sp) sensor near the crank pully, OBDI will not.

OBD0 B16's have a two pin connector (thermoswitch) on the back of the block to the left of the oil filter, OBDI,II have the switch in the thermostat housing.

On the OBD0 valve cover the DOHC text is larger than the VTEC text, OBDI,II the opposite is true.

If the transmission came with the engine, OBD0 will an arm that a cable slips in to to engage the clutch; OBDI,II will have a hydraulic slave cylinder that will engage the clutch.

I THINK OBD0 engines are all 1,000,000 series and OBDI engines are all 5,000,000 series engines (refering to the number stamped below B16A on the front of the block) But I'm not sure.
