RE: oxygen sensor
I,m not sure which one you have but I am going to assume it is a single wire that goes into the manifold. If so you should have one on each side of the engine. You will just have to look for a wire hanging to plug it into. Does it have a wire coming off the sensor? If it got ripped off you will need a new sensor. The wire on the harness will more than likely be hanging somewhere between the sensor and the firewall. It should be the only wire that will plug into the sensor.
If you have a heated sensor you will have 4 they have a 4 wire plug. 1 in front of each cat and one behind. The harness should have a clip that holds the wires to the frame or something close to the sensors.
Good luck.
