The first step is to disconnect the electrical sensor. Next you have to unscrew the fitting. Make sure you take off the old o-ring and put on a new one.Leaving the old one on could keep the new sensor from working properly. The final step is to screw on the new sensor

It is located in the coolant hose at the top, also known as the "top hat" Unbolt the sleeving and check it out, it should be completely obvious and should be a half inch bolt that needs to be removed. Shouldn't take you more than an hour taking it apart and putting it back.

I would take the vehicle to a mechanic and have the a/c pressure sensor fixed professionally. This way I know the job was done correctly.
