Vehicle Application and Function

The presented positive cable harness operates in the rear of the vehicle, with routing possible on both the right and left sides, allowing for flexible installation within the powertrain and battery system. It is responsible for safely transmitting the positive power supply terminal in the BMW i3 I01 generation with the Rex 60Ah unit, ensuring proper circuit continuity and minimizing energy loss.

The red marking of the cable is standard for positive terminals, which minimizes the risk of errors during installation and diagnostics. This allows a service technician or vehicle electrician to quickly locate the correct circuit and perform work in an organized manner, in compliance with high-voltage safety procedures.

Construction, Color Coding, and Placement

The harness belongs to the Cables, Harnesses, and Connectors group, meaning it integrates several sections of the wiring into a single, cohesive current path. The positive cable's construction is prepared for operation in the rear of the vehicle, with the possibility of routing on both sides, facilitating adaptation to factory mounting points and brackets in the bodywork.

The red color serves both visual and safety functions – it allows for quick differentiation of the positive cable from other harnesses in the rear compartment. This is particularly important in hybrid vehicles, where multiple independent power circuits exist, and correct cable identification is crucial to avoid damage to electrical components.

Compatibility with Mini Brand and Service Application

The product is intended for Mini vehicles structurally related to the BMW i3 I01 platform with the Rex 60Ah unit. This makes it a suitable choice for replacing a damaged or worn positive harness in the rear section of the vehicle. The used nature of the component allows for economical repair while maintaining the original cable routing geometry and compliance with factory mounting points.

In workshop practice, such a harness is suitable for:

• post-accident repairs in the rear bodywork,
• replacement of powertrain or battery components,
• diagnostics and troubleshooting of positive power supply issues,
• reconfigurations and modernization projects within the electrical system.

Condition, Safety, and Part Selection

The item is offered as a used part, meaning it comes from disassembly and has been verified for continued operational suitability. For positive cables in hybrid vehicles, it is particularly important that the insulation, connectors, and mounting points maintain appropriate mechanical and electrical integrity. Therefore, selecting the correct harness directly impacts the safety of the entire system's operation.

Before installation, a standard visual inspection of the insulation, sockets, and terminals is recommended, as well as matching the harness routing to the factory cable routes in the rear of the vehicle. A correctly selected and installed positive cable minimizes the risk of overheating, voltage drops, and unwanted interference in the operation of electrical systems.

Tips for Purchasing a Used Harness

When choosing a used positive cable for a hybrid vehicle, it is worth paying attention to structural compatibility with the specific model version, the condition of the insulation, and the completeness of the connectors. Conscious selection of components helps avoid installation problems and reduces the risk of subsequent malfunctions in the power circuit.
