Okay so here is my problem. The other day i had my car running everything was good this was days ago, i start my car today and i only have power to my Tru boost gauge and the oil pressure gauge. headlights will turn on but the motor wont pop em up, no brake lights or interior lights, cluster doesnt work at all. i rev the car up to 2500 my wipers kick in headlights pop on i have interior lights all work cluster works but my gauges shut off. No power to my radio at all, only thing that changed was the battery, and i wired a switch from the bay to the interior, which wouldnt have done anything i dont think it was only extended some wires. Any suggestions? thanks

Sure you didn't ground out a hot wire and blow a fuse?
