i was installing my reciever and everything would work fine but the faceplate wouldnt light up. the only thing it would do is take in cds and the motorized faceplate worked too. i tried to install another deck and it did the same. i checked the wires with a voltmeter, all good until i got to the illumination wire, it has no power. whats wrong with it, and do u guys know how i can fix it?
thanks guys!

didnt post in the audio section because no one really goes there.

 

just tie that wire in with the 12v that goes on and off with the car.

 

Why are you even bothering with the illumination wire? All you need for aftermarket decks as far as power is concerned is a 12v constant, an accessory and a ground wire, and i'd recommend running your own ground and a new fused wire directly from the battery.

 

did you use the Red/Black lumination wire for the radio ground (common thing for (shall we say) less expereinced) installers to do???

The Mazda factory red/black would feed the units lumination wire, not ground.

 

naw i used the orange illumination wire to connected to the orange illumination wire.

 

???

There is no stock orange lumination wire
