i installed my cd player into my car, using a wireing harness to make it easy, and know my interior lights, trunk button and cd player wont work. there is power going to cd player but wont turn on. i found that the car had a security system which they didnt give me a remote for. know would that be the problem with the cd player and other things or did i short something out which i cant see that??? i think i need to take security system out and hopefully it will work.. please help meee
