Audio Systems: Key switched power supply - Ford F250 SD, phone amplifier, lt blue


Question
Hello, I'm trying to locate a key switched power supply in my 2003 F250 SuperDuty that becomes hot when the key is installed in the ignition, and remains hot as long as the key is in regardless of engine running or not.  My need is actually for a cell phone amplifier that will drain the battery if always on, but I need to be able to keep using the amp if I need to switch off the engine while talking on my cell phone.  Can you help?  Thanks much!
