I need to know the wire info on the o2 sensors, both of them

Theres 4 wires.. 2 blk, 1 white & 1 green

What is the white wire for? (sensor or the Heater wire?)
whats the green for? (sensor or the Heater wire?)
I know the 2 blacks are ground, sensor and heater ground.

I just picked up a brand new o2 sensor BUT I i have to cut and reconnect to the honda harness, thats why I'm asking the wire info...

Let me know
Thanks

You were given incorrect info then.

White = signal
Green = signal ground
Black 1 = +12v, switched
Black 2 = controlled ground from ECU

Don't know about your other O2....but aftermarket O2's seem to make OBD2 ECU's unhappy. I'd stick with OEM.
