When I start the car, press brake pedal, and go to put car into gear, the shifter is locked. Sometimes it will let me put it into gear after a while. Do you think this is the saftey switch and how do I replace. There are two electrical components on the breake pedal -- which one would be the safety switch?

PINPOINT TEST A (SABLE & TAURUS) Possible Cause  Fuse No. 17 (15-amp) or fuse No. 32 (10-amp).  Ignition/shifter interlock cable.  Brake Pedal Position (BPP) switch connections.  Wiring harness.  Shift interlock actuator. Diagnostic Procedure 1. Apply the brake pedal and view the brakelights. Do the brakelights illuminate? If so, go to step 7 . If not, go to next step. 2. Measure resistance in fuse No. 17 (15-amp). Is the resistance of the fuse 5 ohms or less? If so, go to step 4 . If not, go to next step. 3. Ensure ignition switch is in OFF position. Disconnect Brake Pedal Position (BPP) switch harness connector. Measure the resistance in Light Green/Red wire between BPP switch harness connector and ground. Is the resistance less than 10 k/ohms? If so, repair short to ground in Light Green/Red wire and test the system for normal operation. If not, go to next step. 4. Measure the resistance in Light Green/Red wire between output side of fuse No. 17 and BPP switch harness connector. Is the resistance less than 5 ohms? If so, go to next step. If not, repair open in Light Green/Red wire and test the system for normal operation. 5. Measure the resistance between BPP switch terminals No. 1 and 2 (component side), while open (OFF) and closed (ON). Is the resistance of the switch greater than 10 k/ohms while OFF, and 5 ohms or less while ON? If so, go to next step. If not, replace BPP switch and test the system for normal operation. See BRAKE PEDAL POSITION SWITCH under REMOVAL & INSTALLATION. 6. Disconnect shift interlock actuator harness connector. Measure the resistance in Red/Light Green wire between shift interlock actuator harness connector and ground. See Fig. 16 . Is the resistance less than 10 k/ohms? If so, repair short to ground in Red/Light Green wire and test the system for normal operation. If not, go to next step. 7. Measure the resistance in Red/Light Green wire between shift interlock actuator harness connector and BPP switch harness connector. Is the resistance less than 5 ohms? If so, go to next step. If not, repair open in Red/Light Green wire and test the system for normal operation. 8. Measure the voltage in Orange wire between shift interlock actuator harness connector and ground. See Fig. 18 . Does battery voltage exist? If so, go to step 12 . If not, go to next step. 9. Turn ignition switch to OFF position. Measure resistance in fuse No. 32 (10-amp). Is the resistance less than 5 ohms? If so, go to step 11 . If not, go to next step. 10. Measure the resistance in Orange wire between shift interlock actuator harness connector terminal No. 3 and ground. See Fig. 19 . Is resistance less than 10 k/ohms? If so, repair short to ground in NOTE: For circuit reference, see CONNECTOR IDENTIFICATION and WIRING DIAGRAMS . For identification of circuits related to this system, but not shown, see POWER DISTRIBUTION article in WIRING DIAGRAMS. Page 1 of 2 SHIFT INTERLOCK SYSTEMS -2001 Ford Taurus SE
