To find the number you are looking for, I recommend the following:
* Check the unit itself: The number is usually printed directly on the ignition control unit, often on a sticker or embossed into the metal.
* Look for the part number in your car's owner's manual: The owner's manual may list the part number for the ignition control unit.
* Consult online resources: Websites like Volvo's official website, or online parts catalogs, might list the part number for your specific car year and model.
* Contact a Volvo dealer or mechanic: They will be able to provide you with the correct part number.
