Fully functional AEM EMS-4 with flying lead connector and USB programming cable.
EMS-4 was fully functional when removed from car. Still has my tune and setup for a Miata running E85.
Connector still has the power distribution system but you would probably have to modify the connector for a few new sensor wires or buy a new harness.
