I've got everything hooked up to the point where I'm testing the install on my Alpine HU. Everything powers up properly and the ASWC blinks like it should and sees the Alpine deck (7 blinks). What I can't figure out is what wire in the factory harness I need to tap to get it to see the controls. What I have connected from the ASWC is the power, ground, 3.5mm wire to the HU remote jack, and the org/grn to the blue wire on pin 14 of the factory harness. The directions that came with the adapter seem to lead down a rabbit hole. I followed the directions and the LED never stops slow blinking green/red, which according to the instructions says it can't see the wheel controls.

I'm not using any of the factory wiring other than power, ground, etc. Non-Bose system. I know I'm missing something stupid here...
