85 Stereo Wiring

When the dashlights/taillights/headlights come on the aftermarket CD player turns off. When I pull the taillight/dash fuse out the cd player will work with the headlights on. I have the wireharness hooked up. The speakers are hooked up correct. The orange(illumination) wire from the harness is hooked up to the black wire from the deck. The red (12v) wire is hooked to a red from the deck. The Yellow(battery) is connected to the yellow from the deck.

The deck works when the lights are off though. Can ya help thanx
