Is this possiable?

2002 chev silverado

how about this cutting yellow wire taping the engine side into the orange and re-program passlock as follows:

Antitheft system consists of a hall effect switch in the ignition lock assembly that produces a calibrated voltage signal as the lock cylinder is turned. The voltage signal is used by the ECM antitheft system. If no or incorrect voltage is signaled, the ECM will shut off. When the mechanical ignition switch fails, it must be replaced along with the hall (Passlock) sensor. The system must be programmed after replacing the assembly.

 To reprogram:

1) When trying to start the engine, it will start and stall.

2) Leave the key on for 10 minutes while the “security” light flashes.

3) When it stops flashing, repeat steps 1 and 2 three more times.

By doing this have I permanatly disable paslock, to read its own restance, by avoiding the key wiring?

i thank you in advance

PS can I get the wiring diagram for these trucks 2002 CHev burb and silvrado
