Decided not to do a head-unit swap after all. Selling an unused JDM dual-zone HVAC unit, faceplate adapter, JDM hazard switch (used), i88 & i85 harness adapters and the Subaru antenna adapter ([URL]http://ae64.com/images-e41/Subaru_antenna_adapter.jpg[/URL]) from ae64.com, and a 14-pin OEM adapter harness. None of these items have been installed, other than the JDM hazard switch is a pull from some car (has some wear on the white paint).
I bought the harness and antenna adapters from directly David at ae64.com, and the JDM parts from someone else. I am not certain the i85 harness includes steering-wheel control wires. It has 3 wires, which I believe is only for AUX port functionality. I'm pretty sure I did not request SWC functionality when I ordered it. I know his newer i85 harnesses always include SWC, but I think I bought mine before he started doing that.
Asking price is $400 shipped in USA. (Inquire with me for Canada, as I'm not sure what the additional postage would be).
Everything included
