As far as I know the white wire is the signal, and the two black wires are grounds, I thought that the green was a signal also because most hondas with 4 wire o2s have two inputs at the ecu. I could be mistaken about the green, but I know the others are correct. Measure for voltage to see if it is hot or not.
