Trunk mounted battery

Why do you care if the CD relay is powered when the engine is off?

The basis is that the CD relay is hot when the key is in on/run or possibly accessory position. Otherwise, the cd relay is a constant drain when the master is turned on.

Find a wire that is hot when the key is turned ON. If you aren't running a heater, the heater power wire is a good choice.

I am not sure if I do. I am not using the original wiring from mopar. I am using an American Autowire kit. And I understand what you are telling me to do, but what I am telling you is nothing in the dash is getting power unless the CD is powered up. SO I believe what I need to do is just wire a switch for the CD in the car and mount in dash to flip before having to start the car, sort of like another kill switch so that the CD gets power when I flip it.
