Have you read through the C4 Audio FAQ?

Yes, I believe I have. This is where I came across the diagram above. I haven't read of anyone actually completing this fix.

Maybe I missed it, but I believe I've read them all.

I still need to know the locations of the wires. I believe one to be near the where the old Bose HU used to be, the other comes from the dimmer sensor...but where to find it.
I'm also assuming the wires are Gry/Blk.

Any knowledge to help me?

OK, I'm guessing I need to tap into the yellow 12v ign. lead, or run from another source(center armrest console has one)
The wires are gry/blk and Purple/white.
They SHOULD be right inside where the stereo is...I think...lol

The wires are located on the harness in the dash that attached to the back of the head unit. Attach one end of the resistor to the purple/white wire, then one end of the other resistor to the gray/black wire, then connect the other ends of both resistors to the 12V ignition wire.
