I took off the radio cover this weekend to tap into the aux input from my XM Roady2 to clean up the look of the dash. I disconnected the passenger sensor to get the panel off and now the air bag light is flashing. I tried the reset - turning the key on, waiting for the flash, turned it back to off (all the way to the left at the point you can pull the key out) count to 5 mississippi turned it all the way to on, repeat twice, total three times. Turn the key back to starting point and waited 5 more seconds and started the truck. Still no luck.
Any ideas what I am doing wrong?
Should I turn the key to ON and then
Back to ACC instead of all the way back?
Any help? How much to have the dealer reset? Is this considered under warranty work? I wouldn't think so.

thanks
