you will need to remove the lower trim piece. It is held by two screws I think and then popout the port that you plug in a dignostic machine to along with the hose and the other sensor on the right side, you will know what I mean when you see it. then once you have it out you take the wire and with the panel turned sideways pull the lever a little and you will see how it will slide into the track. once it is back in the track reinstall the ports/hoses and screw it back in.
