Hi, I need some advice regarding my corolla 2E vacuum setup. The attached image is the vacuum layout of my car, but I am not sure where to connect the vacuum line of the VCV (vacuum control valve) in BLUE color. Those circled with GREEN and RED are to those vacuum hose are connected. But for the BLUE color, I am not sure if it connects to the circled in YELLOW or ORANGE. Thanks for your help.
