HELP! After CD Player Install, NO Illumination
 

After I installed my new HU, using all wiring harnesses, I now have NO illumination of the instrument panel. So at night, I have no idea how fast I'm going, my speed, etc. etc. I have the Blue and white wire(labeled Antenna), the brown (Labeled MUTE), and the orange wires(Both pos. and neg) NOT connected to anything. What do I have to do to illuminate the cluster again??

You might have not hooked up the Orange Illumination wires, but did you take the extra step to make sure to cover them in tape or crimps? If left bare they could touch metal and ground the wire, popping the fuse to your illumination lights. So check the fuse.

BOTH of the orange wires are coming from the harness I got that attaches to the factory radio, so there isn't any orange ones from the new units harness to connect to.. Or do I just connect the orange ones together even though they are on the same harness?

Don't Connect them together cause the orange wire is the 12V+ Park light wire and the orange/white is the (-)dimmer wire short them together and you will burn out the illumination switch and you will need a new cluster.
