The front of the harness has several breakouts, the large 20 conductor ribbon connector, is the main MIMA controller I/O. It will feed across to the left side of the shift console, and will later plug into the MIMA card.
The 10 conductor ribbon is the AUX output. This port controls the fans, the FAS, and has one undefined output (Violet wire).
The White ground wire is to be connected to the metal chassis of the car.
Finally the ECM connections need to be fished under the rug to the ECM area.
