Here are some pictures...
The 14-pin power harness in Steve's 2008 Liberty with McIntosh:

The wire colours and positions match those shown in my pin-out table:
Legacy/Liberty/Outback 14-pin radio harness pin-outThe McIntosh HU has no speaker outputs at the HU (so no speaker wires on this harness). The Green wire at pin 2 is for night dimness cancellation ("bright" mode).
Similar 14-pin harness in a Liberty/Outback w/ McIntosh that was factory-fitted with audio steering wheel controls (SWCs):

The SWCs are on pins 3 and 9, and are the standard colours used across several years (Violet/White and Orange/White). The white stripe is not visible on the violet wire. The silver dots are not mentioned in the wire diagrams.
Steve sent me this -- Subaru's wiring diagram page showing the SWC connections from the wheel to the 14-pin harness:
We need to find where harnesses B36 / i1 are located in your car. These connectors have 28 pin positions, with a cross-section shaped like the drawing at the bottom of the PDF. The diagram is viewing the pins-side of plug i1 (so the layout will be the same when viewing the wires on the back of B36).
See if the 2 SWC wires go into socket B36 (on pins 5 and 6). It's very unlikely that plug i1 has those wires (since the drawing doesn't show any intermediate point they could terminate before plug i26, the 14-pin radio power harness).
