Engine Kubota Part Identification

I'm looking the Kubota part number for the module that controls the primary voltage to the two spark plug igniters. The module has three leads into a potted rectangular plastic package with one mounting hole and marked with the numbers SS3103 and 9L 18. My mower is a ZG227. It has a 27 HP engine with a 60 inch deck.

It may not be a Kubota part it is most likely a engine part and will be on the engine parts diagram.
