You have two, but since I don't know which o2 you are working on, I'll tell you where to find both. The rear plug wires run down along the pressure side power steering hose. In fact the wires are usually wired tied to the hose. The front connector is usually found right by the clutch slave cylinder (where the slave cylinder bolts to the transmission if you have a stick shift) or if you have an atx, just above the center front motor mount.
