A 4 wire oxygen sensor wiring diagram is also called a universal O2 sensor wiring diagram. A four-wired oxygen sensor has four wires, two wires for the heater circuit and two wires are for the sensing element. The sensing element wires go to the PCM, in which one wire is signal ground and the second wire is signal voltage.

If the O 2 sensor heater circuit's negative wire goes directly to ground, look for a short-to-power problem. Usually the heater circuit in this case is controlled by a relay. Remove the relay and retest the circuit. If the light comes on again, locate the short-to-voltage in the wiring harness with the relay removed.

The fuse immediately blows when replaced. Note that the "Breather Heater" (E65390) in the right side of the diagram is wired in parallel with the 4 O2 sensor heaters. Hope you didn't throw the sensors away if you replaced them, as they are still OK as far as any electrical short in the heaters.
