Wouldn't it be best (if you had it plugged in) to unplug it, and reset the ecu and let it re-learn?

Thus, of the two black plugs, the two pin one goes to oil pressure, the one pin goes to the orange/red/brown sensor on the head, and the grey plug goes to the blue two pin sensor forward on the head.
Got it? Good.
If you are working from a wiring harness out of the car I would say to start with a pin out of the DME and then continuity test the plugs.
TLDR (if your car is the same as mine):
black two pin connector = oil pressure
black one pin connector = rear sensor on head, one pin, redish/browinsh in color
grey two pin connector = front sensor on head, two pin, blue sensor
