Cadillac CTS First Generation Forum - 2003 - 2007 Discussion, Retain DIC with Double Din wiring? in Cadillac CTS Coupe, Sport Sedan and Sport Wagon Forums; Open the hood, remove the fuse box cover, look for the two fuses. Choose a fuse, or both remove it, ...
You know what, there are two other power sources.....
The power outlets..... Remember fella's the fuses for these power outlets that are under the hood can be switched. From their factory default of always on, to on with ignition. Heck, that might even be just exactly like a RAP. Where the opening of the door turns it off. Best part, is that you could control the front from separate from the rear one.
I know that ya'll would like "duh" just like I was a minute ago when I thought of those fuses.
^true except for the part about opening the door. Even after you open the door, close it, lock the doors and engage the alarm; RAP stays active for 10 minutes after you turn off the ignition. No matter what. Only the radio shuts off when you open the door.
I tried that in my 05 cts, i even added the extra relay needed. When i put the fuses in the altenate slots the cigarette lighters did not work at all. Could there have been something i did wrong or does it not work for all models.
