Need Alpine wired remote control pinout.
EDIT: Figured it out! Scroll down to Post #9.
Alpine head unit seems to have a standard 3.5mm stereo jack for wired remote input (i.e. steering wheel controls), but for the life of me I can't find a pinout or other instructions anywhere for how to control it. Alpine says to buy a 3rd party adapter, but I was hoping to create my own controller.
I've found the Pioneer/Sony resistor values and connection scheme, but simply connecting resistances across the pins seems to do nothing on the Alpine.
Anybody have information on this? I'm coming up completely dry. Many thanks!
