i put a d3 in my car and everything works fine with the stereo, but now in my 03 camry the check engine light is on. i took it to autozone and they scanned the computer and it came up the speed sensor. so i disconnected the vss wire from the stereo and cleared the code, but the light just came back on. my cruise control does not work. i connected everything properly, anybody have any ideas

sounds like you left something disconnected. or when you tapped the VSS wire, you may have cut the feed. I would check and redo your VSS connection.
