Current Status:
Failure. Can't be done with switch wiring or wiring at the motor. There are no 12v switched wires.
Sunroof Manufacturer has confirmed it can't be done without re-writing the sunroof motor software.
My Conclusion
The sunroof motor assembly probably has the control features inside it that read voltage from the light blue wire (see below), and tells the motor what to do. In order to make this work it seems, I'd have to pull the headliner, dismantle the sunroof motor, find the actual 12v close signal inside the assembly, possibly screw around with the circuit board, etc. I doubt I'll actually do it.
there are 4 wires that go to the switch
light blue - control wire to sunroof motor harness
dark blue - ? to sunroof harness
black - ground
yellow - 12v
there are 5 wires in the sunroof Motor Harness
red - constant 12v+
black - ground
brown - ? - flashes 4 or 5 readings between 9v and 10v all the time (even without touching any switches)
light blue - control wire from switch
dark blue - ? wire from switch
the switch indeed has 4 positions. But instead of 4 12v wires, including one that i can tap into to trigger the 528T, there is ONE wire that changes when you hit the button. It reads one of 5 different voltages depending on what you push (off, open1, open2, close1, close2).
Next Step:
Wait for someone else to come up with another solution.

Ok...
several people i'm sure would love to have their sunroof auto close all the way at the touch of a button.
just need a little advice from electronics gurus here... I'm sure I could figure it out myself, as I made my 2002 SS auto-up and auto-down from the factory remote (with a ton of help from a few write-ups on the web), but i'd rather save some time and have anyone that's already done it or any experts chime in.
The close button has 2 notches -- half way down and all the way down. I would love if it the all the way down activated the auto-close feature. But honestly, if there is only one contact on that side of the switch, i'd be ok with auto-close all the time. i'm never going to close my sunroof halfway, and if i want to go from open to vent, i can push the vent button again.
And if you are concerned about safety, move on the next thread, your input isn't needed here....
I would be happy to attempt this, take pictures, and do a nice write up. What i need to know is:
1. What relays/timers/etc do i need to get
2. What wires go where
3. Has anyone taken apart this part of the headliner, and how difficult is it to get in there to mess around with stuff.
3. is there room to shove the new electric parts up there?
