O2 Sensor troubles

[Axial32]

Ok, so I have made a o2 sensor simulator from a plan online, and it only has three wires, a power, a ground, and a signal. It produces a small voltage pulse. It cycles about every 3 seconds, up to .47 volts I believe.

I just can't figure out what wires to plug into on the o2 sensor pigtail.

BUMP Can anyone tell me what the 4 wire(3 color) are in the downstream o2 sensor circuits.

with a meter you should be able to find
voltage
ground

on the pigtail connector.

the trick will be finding the signal wire on a four wire plug.
unless two wires are signal.
