Application in the BMW i4 G26 high-voltage system

The presented harness belongs to the Cables, harnesses, and connectors group and is a component of the high-voltage installation in the BMW i4 G26. It is responsible for routing cables between key traction battery components and other elements of the HV system, which is crucial for the safe operation of the entire electrical system.

This type of solution is particularly important for:

• repairs following mechanical or collision damage within the battery area,
• replacing sections of the HV installation that require maintaining the original cable geometry,
• diagnostics and servicing of factory high-voltage connections in the BMW i4 G26.

Construction and technical characteristics of the harness

The high-voltage harness in this set was designed by BMW as a factory installation element, which translates into a perfect fit for original mounting points and compatibility with standard connectors. The design solutions used allow for:

• routing cables in a way that limits mechanical stress and the risk of abrasion,
• maintaining proper cable positioning relative to the battery housing and body elements,
• maintaining compliance with the vehicle's factory electrical architecture.

As a result, the harness is suitable both for replacing a damaged section of the installation and for comprehensive reconstruction of the HV system after body and mechanical repairs.

Benefits of using an original BMW harness

Using an original wiring harness in a BMW electric vehicle provides a number of practical service and operational benefits:

• Factory fit – maintaining the original length, routing, and mounting points of the cables facilitates installation and reduces the risk of installation errors.
• Consistency with the HV safety system – the harness is designed to work with the factory safety features and sensors of the high-voltage system.
• Stability of electrical parameters – the appropriate design of cables and connectors helps maintain correct resistance values and connection quality.

Such a solution is particularly recommended for electric vehicles, where the integrity of the high-voltage installation has a direct impact on user safety and the durability of the traction battery.

Condition, verification, and service application

The item comes from the group of original BMW components and is offered as a used part, which allows for cost-effective HV system repair while maintaining factory specifications. Before installation, a standard visual inspection of the insulation, connectors, and mounting points is recommended, as well as performing measurements in accordance with service procedures for high-voltage installations.

The harness is intended primarily for workshops specializing in the service of BMW electric vehicles, dismantling stations, and individual users performing repairs in accordance with the manufacturer's guidelines. Proper installation by qualified personnel is crucial for maintaining the safe operation of the entire HV system.
