In order for the car's dome light to be on with doors closed, there has to be a non switched power line available so it must be there. If the player's power requirment permits it, feed the player from that line. As far as the player's light is concerned, if it is designed to come on and off with the doors, the player must have two power feeds, one switched and one constant. If it does not call for two power feeds, then they have only designed the lights to be operated manually via a switch on the player. In that case you cannot change its operation no matter how you wire it. So I don't think there is a need to disable anything. Just hookup the wire and leave the player lightst off until you need them to be on....ADV said:That would be a nice feature. Your right is is only a 10amp fuse. I've yet to receive the dvd unit so I can't really say how much power I need to run it. From the schematic I don't see the unswitched direct power line though. I'm thinking with the 3 positions of the domelight (off/door/on) you would end up with, no power, on an off with the door closure, on all the time except for 30 minutes after key has been removed from the ignition when the battery saver kicks in, respectively. The later sounds good but I would have to disable the dome light of the dvd unit because since the entire unit would be wired to the same circuit it would have to operate in the same way, hence the dome light would be on when the dvd player is on. I can't really say I know what I'm talking about here, just guessing. What do you think?
