ECU

[KMG]

Hi all, I'm slowly going crazy, I'm wanting to test the power supply to the ECU before I have it cloned but for the life of me I can't find a diagram showing the power wires, I've tested the wires from the ECU to the injectors and they're good, so this leaves the wires to the ECU, does anyone have a diagram or know which wires I need to test?

This is my ECU
