Used BMW engine wiring harness (module 1), OEM part number 8743493, a genuine used component removed from a donor vehicle. This harness is specific to the 2.0L turbocharged four-cylinder engine (1998cc, DOHC) found in the BMW 330i and Z4. It connects and routes power and signals to engine sensors and actuators; failure often causes intermittent misfires, no-start conditions, or sensor communication errors.
