    Was this the same head unit that the vehicle came with?

    You can see what the vehicle shipped with by entering the VIN at : Welcome to Toyota Owners

    If you have the time, try digging around in here. Please report back when/if you find it.

    <dir> 05 is P-codes and related.

    What are you looking for? A photo of the electrical plugs that go to a 2005 JBL system radio so you can see what color codes go to which pins?

    Maybe this is what is confusing me. If you have pictures of the connectors and wires, doesn't it show the different color coded wires and the pin positions they belong to? I'm not talking about a wiring diagram, I'm talking about a real photo of the car side wire harness.

    In the link @SFO kindly shared, which has a copy of a preliminary (and long-obsolete) edition of the 2004 Repair Manual (more info), see these Terminals of ECU pages:
    They also have the Electrical Wiring Diagram, in which see these System Circuit and Connector List pages:
