    Okay so, I have literally spent 2 weeks trying to figure this out.
    Countless searches of all the forums and videos.

    But I'm stuck...

    Atoto A6 Pro A6Y2721PRB
    Metra Axxess ASWC-1
    Metra Axxess AX-TOY28SWC

    Connected the AX-TOY28SWC to the factory harness and AWSC-1, but no "out" to Atoto A6 from the connection to ASWC-1 because the 3.5mm SWC doesn't work (tried that too)
    ASWC-1 came with a harness, so I pulled the pins out of the connector at the end of the AX-TOY28SWC (end that plugs into ASWC-1) and spliced them to the included ASWC-1 connector

    ASWC-1 sees all steering wheel controls when programming
    Auto program seems to detect everything fine
    Manual program works. ASWC-1 sees each button and I programmed them accordingly
    Manual Radio Type program seems to work, but I tried all 16 manual modes to no avail

    I think the problem is that the A6 is not receiving the signal, but I can't find anything on which colors are supposed to go where. The few that I've found are the complete wrong colors for the wires.

    I absolutely can not get the A6 to program the buttons
