Hey guys. Got the circuit working on a breadboard. Playing with voltages, etc to make it look the best day and night. Using PN2222A transistor to convert the open ground of the e46 lighting to a switched power; common ground required to power DCT shifter.
Going to get leather professionally stitched @ my tailor to close opening in front made to accomodate signifcantly larger DCT shifter. Going to cover-up the current PRND M/S lights on console using that spray on plastic stuff (can't remember name). Then assemble original circuit board and inverter circuit board into a small enclosure which will mounted to left of shift selector under console.
Hopefully have it done tomorrow (Sunday)........ Will post more pics when it's further along.
