Here's the short of it.
My radio isn't getting power, and checking the wiring diagrams, I have narrowed it down to an orange wire. It has no juice in the amplifier plug, in the middle, or up front at the radio itself. The wire was checked with the ignition in acc and ALL fuses are kosher. This leads me to think of a circuit breaker or a fusible link. Are either of these related to the radio ? I don't wanna tear into the glove box unless I have to. I checked the rear defrost and it has power (it's indirectly related to the radio in the wiring diagram, so I checked it.)

I doubt it's the radio itself, as it's not getting power.

thanks for any help guys.
