=== 4-Way Flasher Function (Emergency ON)) ===

* Connects power from the
'''Red/White'''wire to the'''Green/Yellow'''wire, while disconnecting the Blue wire from Green/Yellow. - Routes the return signal (Green wire) to both
'''Green/Red'''and'''Green/Blue'''wires, activating both sides.

So when the emergency switch is ON, constant 12V flows through the Red/White wire → Green/Yellow → flasher → Green wire → both L/R indicators via Green/Red and Green/Blue.
