Wiring harnesses

In Simple Terms

This rule covers the wiring harnesses (electrical cables) that connect the power unit to the car but aren't normally part of the power unit itself. These are the car's own wiring looms that link the engine to various systems. The regulations ensure these connections are properly managed and don't give teams unfair advantages.

• Covers electrical wiring that connects the power unit to the rest of the car
• Distinguishes between power unit internal wiring and car-specific looms
• Ensures standardization of how power units interface with car electronics
• Part of technical regulations governing power unit installation
