    I searched for this for a long time and never found it a couple-few years ago... If it was a Honda, I'd have it for you but Toyota is a hassle...

    Acenbay.com spent big on the tooling to make these wiring harnesses so you can ask him if he knows, but I'm fairly certain his wiring color codes are different than OEM wriring codes.

    It's easy to find in the Electrical Wiring Diagram. Toyota Service Information and Where To Find It | PriusChat

    I'm pretty sure it's been screenshotted and attached to PriusChat posts more than once. Try searching for old posts about which end of the battery to count module numbers from (it comes up in some of those discussions).
