	{{PCB Picture\|side=front\|labeled_filename=5WY1900-Front.jpg}}		{{PCB Picture\|side=front\|labeled_filename=5WY1900-Front.jpg}}This page documents the '''SIMK43 (5WY19)''' ECU hardware. The goal is to make the ECU easier to understand, inspect, and work with by providing a clear reference for board connectivity, key circuits, and component placement.

			The full ECU electrical schematic and PCB files are maintained on GitHub and are the canonical source for the latest revisions, updates, and related notes: [https://github.com/OpenGK-org/ecu-reverse-engineering/tree/main/5wy19 https://github.com/OpenGK-org/ecu-reverse-engineering/tree/main]
