Panasonic HU ?'s for 99 Corolla VE

[dimwittedmoose51]

I Have a used(by my son) Panasonic CQ-C7303U and am in the process of putting it in my 99 Corolla VE. I assume that it will fit as it appears to be no bigger or deeper than most of the units previously discussed here. My question concerns the soldering of the interface cables to the Panasonic. The interface cable has all the matching wire colors except for the orange one which is labeled for dash illumination and that makes me think that it also controls the dimming of the factory radio. Since the Panasonic likely has not corresponding wire (has a blue wire for power antenna and a blue white wire for triggering a separate power amp), do I simply cut it off(or tape it) or should it be tied into the red or yellow power wires. The reason I ask is that wiring a similar situation on our Subaru, I thought I had everything just right and ended up with no dash lights at all.

TIA

Just tape the end of the ORANGE wire so that there's no possibility of any short circuit of the vehicle electrical system....... then secure it to the remaining wires. Do not connect it to any other sources.
