I've found out today that I only have one oxygen sensor hooked up. The passenger side is missing. I can't find the sensor jack. Shouldnt it just be hanging there like the right sensor jack is?

Anybody know where to find electrical schematics so I could find what wire the sensor jack is coming off? or any kind of advice.

No wonder why my gas milage was so crappy.

They wont show you anything that is easy to read. I have a magnifying glass around that I use to read those things, and I have 20/20 vision in both eyes. I will attach a tmoss diagram, you are on your own locating it in your car, but this will give you wire colors to look for. And as stated it prolly comes out of the same harness as the other one, so follow that harness.
