Congratulations! You have made it through, now just connect the bottom board, add the
knobs, connect the expansion to the main board and you are ready to enjoy your new
module.
Before you connect anything, make sure that your system is disconnected from power. Also
double check the polarity of the ribbon cable, the red cable should match the 12V rail both
on the module and on the bus board! And make sure that connection cable on both modules
are in the same side!
