My Nissan micra K11 had a aftermarket stereo system and blue led's in the clocks which worked fine together. I was going to swap it for a 53 plate Corsa so i took all of my stuff out. Then I decided to keep the car so i sorted it out again and now the stereo wont work and neither will the dash lights, also when i rev the car up then the interior lights and brake lights will come on because something is faulty. Please can someone help me if they can because i really don't know what has happened thank you.
