02 Sensor

[88pathylove]

OK i accidentally ripped the wires off of my 02 sensor, bought a new one and the wires don't match, the 02 sensor is universal type 3 wire (heated) and has 2 white wires and 1 black one, the end of the stock plug wires coming from the car are 1 red, 1 black ,1 white, so what I'm wondering is what is the + , - and signal coming from the car. Also the instructions were not very clear so if any body has a way to test the output on the 02 sensor to find + , - and signal that would be great but if not i think i can figure it out, thanks.

IIRC red is 12V+, black is - and white is signal.

IIRC red is 12V+, black is - and white is signal.

 

 

I dont see red on my wiring diagram fora 1995. But it does show white to go be signal for the ECU.

Here is the 1995 FSM diagram:
