Other connections
Connect the white wire from the shift console end of the harness to the cars metal chassis, to complete the grounding of the power /fan control circuit.

Everything should now be connected,except the ECM wires, and the MIMA bypass connector. We are ready for the power up test. Whenever powering up a board or system for the first time, the most important thing to watch for is shorted power supplies. This is especially true with MIMA as we use the +12V and 12V from the battery sensor to power our opto coupler input. The rest of the system runs off of the 13.6V main power that has been regulated to 5V. Most modern power supplies can take a shorted condition for a short time without permanent damage, so we will quickly confirm the main 5V power supply first, then turn off the system, reconnect our probes to the +12V and 12V and turn the system back on again to confirm those power supplies.
