Battery → Main Fusible Link → EFI Main Relay (triggered by ECU pin A4) → ECU pins A1 and internal coil drivers.

If voltage drops below 4.5V, unplug the MAP sensor and check if voltage recovers. A shorted sensor often pulls down the entire 5V reference rail. ⚡ Wiring Best Practices for Engine Swaps

I cannot generate a literal image/PDF, but I can give you you can use for a blog post, video description, or repair guide. You would then add actual pinout diagrams (scanned factory manuals or hand-drawn tables).

The ECU is typically located under the dashboard on the passenger side, behind the kick panel, or sometimes in the engine compartment near the battery. Once you've found it, you can usually confirm you have the right unit by checking the part number. Common part numbers you might encounter include 89560B2360000 and 89650BA890 . For the Move L9, the ECU typically uses large, multi-pin connectors, often with a black plastic housing and a lever or bolt to secure it. The number of pins can vary, so it's important to count them to find the correct diagram.
