Outer Limits 4x4 Board

Well i put an amp and 4 speakers in my triton yesterday and i had to unplug the passanger air bag so i could get the shroud out behind the glove box and ever since the air bag light has been on???

have checked the connection and its alright also disconnected the battery over night in the hope it might reset the computer.. any ideas?????

It sounds like it's logged a hard code in the ECU. You will need to go to someone with a scanner and delete the code i would say.
