I am in the process of wiring up the rear O2 sensor in my 2000 build. I am not sure if it makes a difference, but its a California emissions car. there was no rear sensor, near the driver seat(it was under the hood) like on the federal version but the wiring harness was there.
So i was going to wire up the rear sensor off of this part of the harness but both the harness and the O2 sensor had female connectors, and the wires are different colors.
My question the O2 sensor i have has for wires one white one blue and two black.
My plug on the harness has Black red, black white, red, and red yellow.
1) if i wire this wrong could it damage the computer or will it just throw a code?
2) are the two black ground wires interchangeable, from looking at the two plugs and the location of the wires I am pretty sure i have the white and blue wired the same but the two black wires on the sensors are all black no way to tell the difference between the two.
