just got done installing my returned pcm from sc. truck fires right up now and has plenty of power. only thing now is. the speedo dont work, but the tach and temp guage do, controls for the heat are stuck in one position, no a/c, no heated seats, engine light is on, abs light, brake light, frt airbag light,

 

...send it back...I would make sure that they cover the shipping costs.
