i purchased a passenger airbag cut off switch and installed it and it won't work i have a 2002 ram 1500 qc called the dealership and they said it is just plug and play for my truck when i turn it off the light doesn't work and tried two switches anyone have any ideas thx

 

The service manual doesn't offer much help...
"The passenger airbag on/off switch connects one of
two internal resistors in series between the passenger
airbag mux switch sense and passenger airbag
mux switch return circuits of the Airbag Control
Module (ACM). The ACM continually monitors the
resistance in these circuits to determine the switch
position that has been selected. When the switch is
in the Off position, the ACM provides a ground input
to the switch through the passenger airbag indicator
driver circuit, which energizes the Light-Emitting
Diode (LED) that illuminates the Off indicator of the
switch. The ACM will also illuminate the Off indicator
of the switch for about seven seconds each time
the ignition switch is turned to the On position as a
bulb test. The ACM will also store a Diagnostic Trouble
Code (DTC) for any fault it detects in the passenger
airbag on/off switch or indicator circuits, and will
illuminate the airbag indicator in the instrument
cluster if a fault is detected. For proper diagnosis of
the passenger airbag on/off switch or the ACM, a
DRBIIIt scan tool is required. Refer to the appropriate
diagnostic information."

If the switch wasn't installed at the factory, I wonder if the ACM would need to be adjusted in any way.
