Hello I need help knowing which color wire goes to the o2 sensor on the drivers side. I understand that the o2 sensor does not have the same colors as the engine harness. Here are the wires from the engine harness.

There's 4 wires to each sensor. Do you know which one is fried there ? I'll attach the wire diagram. The sensor wires are shown on the last page. Good luck.

Maybe the best thing for you would be to buy a new O2 sensor and a new connector to solder to the wires. Or hit up a junkyard for both connectors.
