4000S Quattro Stereo Wiring: Where is Switched Power??

[J Baker <jbaker7@Yahoo.com>]

I am ready to install my new stereo, and figured out most
of the wires.  Besides the speaker wires, there are 3:
Red - always power, White - antenna signal (I think),
and Blue/White - lighting (tied to dash dimmer knob)

But I CAN'T FIND a switched power wire!

What color is it?  Is there one?  If not, any hints on where to wire
this from?  Or (gasp) should I just connect it to the Red power wire?

Please help!
