This is the connector which acts as a bridge between the evaporator and main harness. Notice the amount of vinyl tape wrapped around the harness; as soon as the PVC tape was unwrapped, a real mess was hidding. Cables were cut and twisted together (not even soldered!), unportected by PVC tape and on top of that some of these cables had melted insulation. This means that during the past a serious electrical fault occurred in the donor car.
