Ok, I figured out how the buttons are wired up by following the traces... When i have some time I'll take my notes and put them in an electronic file to post up here. There are a couple more wires on that connector i wanna follow, but hey, at least I'm making progress! After that it's the display connector to tackle.
I wanna just reiterate more concisely too since my last post was so long: figuring this stuff out would give us SO many more options for mounting things in our dash, giving us way more freedom to do what we want with our cars and make our aftermarket addons look more factory. To me that sounds really good, but i haven't seen any buzz here yet...
