well from what i've heard reseting the button is mainly put the key in and thats all. shouldn't cost that much. but i mean the airbag light came on. maybe you might of done something slightly to a sensor. Lights normally go on for a reason. i really wanna see your pictures of the gauges. did you have any issues with the wiring it self. isaw that you had an issue with the whole needle. how did you get around that.
