    I thought it was starting from the ECU Block #1 to block #14 being at the end. Is this correct?

    I’m seeing conflicting information online.

    Yes... Or at least that's what Dr. Prius told me in an email... An then I later confirmed through a wiring diagram for where negative terminal connects.

    Gen2 - block 1 opposite side of ecu
    Gen3 - block 1 same side of ecu

    confusing

    The ECU switched ends between Gen 2 and Gen 3, so I guess the block direction didn't, really.

    If ya'll do a deep dive into PriusChat threads you'll notice that it has been a chronic source of confusion for a long time...

    Indeed it has. There are many threads in this forum which ask the same question and there are conflicting answers but in the end it seems this is correct 2E25E70E-1825-4B92-97D3-86ECD9826769.png

    I swapped out 5 more cells today and my car was running good, hoping for another 15k miles!

    Civilization will no longer function when we lack the ability to think critically... But if your kink is enslavement and supporting dictatorships, then the gift of each individual being empowered to think critically is your mortal enemy because it can eventually bring out the best in humanity. And things aren't looking too good in the critical thinking arena in recent years.
