This connector is used in BMW ActiveHybrid (3, 5, 7 series) and Mercedes-Benz hybrid model HV harnesses. Always verify against the vehicle-specific wiring diagram before ordering.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: Can I install this connector myself?\u003c\/strong\u003e\u003cbr\u003eA: No. HV hybrid system connectors must only be serviced by qualified technicians with HV safety training and appropriate PPE. The HV battery must be de-energized via the service disconnect plug before any work on HV circuits. Attempting HV connector work without proper training and equipment is extremely dangerous.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: What is the difference between the HV system and the 12V system in a hybrid vehicle?\u003c\/strong\u003e\u003cbr\u003eA: Hybrid vehicles have two separate electrical systems: the \u003cstrong\u003e12V auxiliary system\u003c\/strong\u003e (standard automotive electrical, powers lights, infotainment, ECUs) and the \u003cstrong\u003eHV traction system\u003c\/strong\u003e (200–400V DC, powers the electric motor and is charged by the HV battery). The OEM 1355328-1 is part of the HV traction system.
