An ignition coil harness is a wiring assembly that connects the ignition coils to the vehicle's engine control unit (ECU) and power supply. It facilitates the transfer of electrical signals and power necessary for the ignition coils to create sparks that ignite the air-fuel mixture in the engine's cylinders. Proper functioning of the ignition coil harness is essential for efficient engine performance and reliable starting. If damaged or faulty, it can lead to misfires, poor fuel economy, and starting issues.
