i have code po851 park/neutral switch low need location of switch

its on the clutch peddle to keep it from starting til the peddle is depressed. it can be bypassed, but then the car will start while its in any gear.

it is under the dashboard above the clutch pedal, you will find a switch connected to a wiring harness. its purpose is to prevent starting the vehicle unless the clutch is disengaged. I worked on cars since 1993 and honestly never saw a clutch peddle...what was it peddling?
