    I took the plunge and removed my dashboard today. My intent is to remove the 11.6" vertically-oriented head unit from my 2017 Prime Premium (non-JBL) and replace it with a landscape Android head unit.

    Two main problems I see (so far):
    -The head unit faceplate's top air vents do not marry with the internal ducts like I'd hoped. Currently thinking I'll cut off the front half of the internal duct and then duct-tape them together
    -The physical control buttons in the landscape faceplate utilize an 8-pin connector (90980-12551, I think) and I'm not seeing a match for that in my dash

    Can someone smarter than me help me understand the wiring diagram? It seems to me like there are three wires in an 8-pin connector that must appear elsewhere in another connector(s). For instance, the diagram I found seem to indicate that pin 6 should go to *9 (pin 9?), but pin 9 of what?

    I've looked all through the manuals at cardiagn.com but the seemingly relevant connectors there don't seem to exist in my car. I think I could manage finding sources for ignition voltage and GND but I can't seem to find a connector with LIN1 (BE whatever than means) to the CANBUS.

    You're probably going to struggle without the full hyperlinked original document from TIS.

    I don't have access at the moment myself, but some notes.

    The *9 is referring to the note in the corner - "before 2018 production".

    The letters are colour codes for the wires - BE = beige, SB = sky blue, LG = light green. (The colours you can see anyway in the colour version of the diagram.)

    The "AC Control assembly" should have a single connector because there's no "A" or "B" marking on the connections, only pin numbers. Must be at least an 8-pin connector - other pins might be shown in other diagrams.

    But I'd guess that "AC Control assembly" is actually on the mechanical thing with the servos, not the user controls you're messing with. You're probably connected to the other end of that LIN1 wire. But that could be a different colour by the time it reaches you. You need the previous page of that diagram to see where that wire's going.

    Thanks for that.

    I bought the 2-day TIS subscription. I'm not finding what I'm after. My current thought is that the relevant signal I need are in the 24-pin or 28-pin connectors to the back of the 11.6" touchscreen. I see several wiring diagrams, but none of them describe how many pins the connectors have. I've tried searching in Library/Service information for keywords like jbl, 11.6 but am not finding connector pinout illustrations.

    A/C amplifier assembly (I60, I61, Z1, Z26) Pin 14 seems to be Lin1 but not sure where to find those.

    There should be some sort of hyperlinking so you can click on a connection and be taken to an illustration of the actual connector involved. You might need to highlight something in the diagram, then hit the right control button.

    All the physical information like connectors, wire harnesses, item locations are off in a separate sections from the logical wiring diagrams.

    Seeing both ends of that LIN1, you're looking at a connection between two parts of the A/C system. I don't think you've found what you're after, which is the multimedia display.
