This used OEM BMW engine / ignition coil wiring harness, OEM part number 7850995, comes from a donor vehicle. Also called the ignition coil wiring harness, it supplies power and signal to the coils on the 3.0L turbocharged I6 found in BMW M2, M3, and M4 models. When this harness develops a fault, common symptoms include misfires, rough idle, or a no-start condition due to interrupted spark delivery.
