    Would anyone here have a wiring diagram for 2012 Prius JBL system? My amp cut out and I'm trying to see if I can find the cause of the failure.

    It's just the regular wiring diagram for the car:

    Toyota Service Information and Where To Find It | PriusChat

    It has the various JBL/non-JBL, nav/non-nav options all shown, in different sections or with different numbered asterisks by the wires.

    You're welcome to these quick notes I cribbed eight years ago, but they're definitely terse. Looks like I wrote them in a [number][circuit]=[color] format, which would mean connector L130 position 9 is the CANH circuit and green, position 10 is CANL and white, and so on. Notes like (nxt 3) or (prv 2) I added on shield drain connections to indicate which circuits run in that shield. Beyond that, I myself would have to look at these notes a lot longer to figure out what I meant by them eight years ago.

      Oh, and by the way:
