HELP!! is300 nav housing + alpine screen installed but wont open
 

HELP!!

ok, so ive done weeks and weeks of research on here, my.is, and lexusownersclub.com. i purchased a used motorized nav housing (that the owner said worked) and retrofitted a nice alpine screen inside. i hooked up the 12v+, acc, GND the way that was discribed in the DOC on my.is as follows:

"Connecting the circuit board
This will be the hardest part of putting your system together. Looking at the rear of the control circuit there are two large plugs. The largest one is where you will connect your wires. There are small prongs inside the plug and you can either solder the wires on or use small female connectors. Be sure that NO pins are touching each other or you might short your circuit board.

The wiring goes as follows:

(12v+) - Top right corner pin of the large plug
(Acc.) - Bottom right corner pin of the large plug
(Ground) - Bottom left corner pin of the large plug
"

but the unit doesnt appear to have any power...at all. no button functionality. or anything. did i do something wrong? anyone know?

i also searched this diagram:
