98 Tahoe overhead Console rear ac wiring

[newyorkin]

I have a 98 with NO rear AC option, so I have the blank panel in the overhead console.
I just popped out the blank to look into wiring accessory switches there, and I find the harness for the rear AC controls capped off and sitting there.

It has 6 wires, so that's 5 switches I could wire up there if I cannibalize the other end.
Anyone know where this harness terminates? I couldn't find anything by the ebrake that looked like it, and I'm at work, so no book and I can't take the dash apart.

TIA!

What color and size are the wires?

They vary in size, but appear minimum 18ga. All good for a relay coil.

I think it's:
white
grey
blue
black
orange
red

All but the grey should run to the back corner where the auxilery heater box would go. The grey wire should run down and tie into the dash lights probably at the distribution box under the dash.

Ah, thanks. So they probably won't work for me anyway.
