there aren't very many orange wires. one goes from your Multifunction switch to your Auto Park Lamp Relay and your Park LPS fuse.
3 orange wires come out of your BCM for power to your internal lights.
(1 powers the lights, the other 2 go directly to fuses)
thats almost ALWAYS the INTLPS fuse. either under the hood, or top right of the passanger fuse box.
if not... you might have burned out that small segment of your BCM. not quite sure how... but i can't give you a good reason why they aren't working, other then that.
