First, everyone with a Reatta needs the factory service manual. It is a good idea to go through sections 5E, 6, and 8 just to become familiar with everything. For example the inverter schematic is in 8A-88

Wire Code:
C1 (gray) =12vdc
B (black) = ground
A (white) & C (blue) =110vac

The inverter is variable so if you put 9v on the input (C1 & B) you should get about 85vac on the output (A & C). (See photo below) This is how it dims.

BTW the OEM (or one of) is still in business but I have not checked to see if replacements are available.

GM part numbers:
1642274 (black)
1642275 (pink)
