    Hello, I'm resurrecting a Prius. I'm in the stage where i noticed that when i connect the scan tool the check engine light turns on. Removing the scanner will turn off the check engine light. I measured the wires at the obd connector and the brown wire nr 5 does not have ground. Since the car was soaked in water i do not only want to check the ground but the complete connector Al2 and DA2. Can you guide me to the connectors?

    DA2 can also be seen in this old pic (showing engine water pump circuits that also run through it):

    I found both connectors and they were in good shape. The problem was with the ground connectors on the valve cover. Gave them a good clean and all was good. Still no start but we are getting there
