In a nut shell I agree with bigJim, you didn't mention anything about checking the fuse. I would start there also you might want to pull the fuse and check your hotwire (+) to ground using a ohm,or multi meter make sure the wire isn't shorted, after that short one end to ground with no power applied and check the other end to varify you have no opens in the wire. also with everything hooked back up and power on check your connections wiggle them maybe a wire pulled out of the connector and it needs to be reseated.
