I installed the pioneer mp3 player head unit in my xfire. Installation was smooth thanks to the posts around here. It sounds and works great... BUT

My rear spoiler now deploys at around 5 mph and stays up. The light on the spoiler dash switch blinks and the switch is inactive until i turn the car off and back on again. This problem occurs whether the radio is on or off. I can't imagine what I did to mess up the spoiler. Do you think i could have messed something during stuffing all the audio wires down behind the dash?

Any help is greatly appreciated!
