Howdy again!

I put up two posts elsewhere on this thread with my investigation... on the double-din metra harness, the leads run:

Blue (antenna +) --> +-B
Orange (Illumination) --> ALM
Yellow (12v) --> -B
Yellow (12v) --> Safe
Black --> Ground
No Lead --> CAN+
No Lead --> CAN-
No Lead --> MUTE

That's the scoop... perhaps the orange is in fact switched and I can forgo illumination features?
