Pinout for the Smoothieboard LCD connector?

The C3D GLCD has been out of stock for ages.

I’ve got a generic reprap one (let’s be honest, it’s the same thing) and have been attempting to figure out the pinout by working backwards from the firmware. Attached is where I’m at. It’s close… it powers up and seems semi-functional, but it’s not there yet.

PIN 01 == EXP1 Pin 10 - VCC
PIN 02 == EXP1 Pin 9 - GND
PIN 03 == EXP1 Pin 3 - MOSI
PIN 04 == EXP1 Pin 5 - SCK
PIN 05 == EXP2 Pin 8 - Back Btn
PIN 06 == EXP1 Pin 4 - SPI Chip Sel
PIN 07 == EXP2 Pin 1 - MISO
PIN 08 == EXP1 Pin 1 - Buzzer
PIN 09 == EXP2 Pin 3 - Encoder Pin A
PIN 10 == EXP1 Pin 2 - Encoder Btn
PIN 11 == EXP2 Pin 5 - Encoder Pin B
PIN 12 == Not Connected

Can anyone offer any input? Thanks!

Really this would be as simple as anyone who has an official one just matching up the pins on the little adapter board using a multimeter continuity check.
