So I did a bit of digging and Red/Grey wires are universally interior lighting(what you want for auto dim and night on off). You have one because the ash tray has interior lighting. Figuring there would be one for the radio and climate control, I pulled off the center stack trim and looked around inside.
Bingo, hiding in the wiring harness. I tapped it with a vampire clip as there was no room to solder and ran a a lead back up the center console to the shifter.
Soldered it together at the knob and then tapped the ground that was in the center console already.
Perfect function with dimming to the OBC controls. Functions as if stock.
