Question about Pioneer DEH-P5800MP CD Player
I have had this stereo installed in my car (85 Corvette) for 6 months with no problem. The power antenna motor wouldn't turn off so I disconnected the wiring to it; when I did this the head unit and interior lights would not get any power either. I reconnected it, but stil nothing is getting power. I checked all the wiring and fuses that I can get to, but I no longer have the keys, so I can't get the head unit out of the dash.
On alot of vehicles, the power ant and/or illumination wire for the factory radio ties into the "courtesy circuit". Normally, the scosche factory plug adapter takes the proper action with this wire. For custom install, sometimes it's needed to ground this wire, sometimes it need be tapped into the deck's "remote" (blue) wire, and sometimes it need be left alone! Example, on a 1987-1993 S-10 pickup, you need to connect the "ill" wire of the aftermarket deck to this (usually orange) wire in the dash, or you'll have no dome, dash, or running lights... hence "courtesy circuit"!!! hope thius helps!!!! and footnote, its always good to hook this wire up as most decks nowadays will have an automatic dimming feature that senses the voltage of the dashlights being on... so at night when you hit the headlights, the deck will dim to ease the eyballs.

When you get the keys, or whatever try unhooking the power antenna wire as it comes out of the back of the stereo. Otherwise your guess is as good as mine.
