It depends aloft the manufacturer how they architecture the this wire is a voltage arresting wire agency the voltage produced by the sensor will accelerate to the car computer. Each part ought to be set and connected with other parts in specific manner. What i do remember is the following.

Automotive engines are composed of a complex set of systems that are monitored by several types of sensors.

On gm it would be black or have black stripes on it as with chrysler cars. I was going to use a 4 wire sensor but to run the wiring was too much trouble so i used a universal 3 wire o2 as it was easier to install. Signal black. These wires serve to heat up the o2 sensor to bring it up to the o2 sensor signal gives an indication of oxygen content sensed by the probe.
