earlier today whilst driving through the massive droughts around here

the STOP oil check light cam on after pulling over and getting soaked checking the oil and swearing loads found still had loads of oil.
tried turning ignition on and off still no good so decided to risk the half mile to garage and as soon as i moved light was flashing on and off like a tacky disco light so came to the conclusion ( all by myself) that i had dislodged the wire to the sensor
so question is where is the sensor located on an 2001 1.4 8v plz
