mitch1965, one end inserts into a receptacle behind the splash shield while the other end connects with clips to the brake pads. There are some great instructions [http://www.northamericanmotoring.com/forums/how-to/38346-maintenance-changing-front-brake-pads-for-beginners.html|on here.] After replacing the sensor, turn the ignition key to the #2 position for around 30 seconds without turning over the engine...the light should now go out! Hope this helps, good luck
