i put an aftermarket radio in my stang and now since then my tcs switch and pass. airbag warning lamp are inop. the tcs switch when u press says off but doesnt really turn it off. the pass airbag says its off when u first crank it then turns off even if no one is in the seat. the airbag light also flashes every three seconds or so. i didnt touch any wires in the car used a harness. anyone help me here or take to a dealer?

Hmm that's really strange.. Did you plug the top wires back in? Or by chance get them reversed?
