I have a 99 R/T cc.Today I swapped in a digital overhead console,nice and easy but the check engine light came on when I statred it.No big deal I guess.Then next I swapped in a set of power mirrors.All the wiring was already there pluged it all in and turned the key on and had no power to the mirrors.Then while checking that I realized I had no power to anything,no starter,radio,lights,nothing.The only thing that works is the chime when the key goes in and the gauge lights.I need some help to get this running again.It seems as though I tripped some security system.There is a red LED on the bottom of the dash under the steering column but it has never done anything.I don't know of any alarm on my truck.And I don't have a service manual or owners manual for this truck.Any ideas guys?
