BMW 328i Engine Wiring Harnesses

Your BMW 328i came with an engine wiring harness that was installed at the factory. While you may not think much about it, it's an important component as it organizes the wires, cables, connectors, and terminals that control all of your electrical components.

What a Wiring Harness Does

Your original engine wiring harness relays electrical power to parts like the alternator, battery, fuel injector, windshield wipers, headlights, and more. In short, anything that require electricity to operate depends on the quality of your engine wiring harness.

How to Tell Your Engine Wiring Harness is Going Bad

If your wiring harness gets damaged, you need to replace it as soon as possible. If you notice any of the following, have yours tested to ensure that it's operating properly:

• Your front or rear lights aren't working
• Some electrical components stop working
• You have ignition trouble
• Your battery dies or quickly loses its charge
