i want add another amplifier to my 1999 cadillac seville but i cant find a remote wire. i need the 1999 cadillac seville wire diagram. anyone?
Rey, technically you could connect your 1999 Cadillac Seville amplifier turn on wire to the radio switched 12v+ wire. That way your amplifier is on whenever your 1999 Cadillac Seville is on and off whenever your 1999 Cadillac Seville is off. If you need a switched power source, run a wire to your steering column and use the brown wire in the ignition switch harness. Just make sure to run an in-line fuse holder with a 1-amp fuse on the amplifier turn on wire. Hope this helps. Good luck with your 1999 Cadillac Seville amplifier installation.
