i searched this topic and every thread has a diff answer for some reason.. can someone identify the wires on the back of this 99-00 o2 sensor harness.. 2 black wires, which im assuming ground and can be switched without making a difference, one green, one white.. which is the heater signal and which is the power?

anybody?

 

actually the blacks are heater resistance wires. one goes to a 7.5 amp fuse. the other is just there to make resistence. now, green is signal, white is ground.
