Can someone ID and explain these wires for me please?

Previous owner cut the OEM radio harness plug off and so I was left with a bunch of dangling wires. I'm trying to install an aftermarket radio. Well, I ID'd all the speaker wires and the ground/constant/switched wires...but now I need help figuring out what these are.



The diagram in another thread says the purple/white is a PWM wire? What is that? I also have 3 green wires, a yellow and a gray. I'm guessing the yellow is DIM ENABLE, the gray could either be DIM SIG (?) or steering controls, and I have no idea what to make with the remaining 3 as they are different shades. Please help?

Okay, I checked the wires going into the actual power antenna (not sure why I didn't think of this earlier) one of them matches the DARK GREEN wire in color, so #2 appears to be the power antenna wire...

It's a very vague memory since I did it so long ago, but I remember the steering wheel controls being a green wire. For some reason I think of gray as dimmer. Put a voltmeter on them and check. If green is strg wheel, pressing one of the steering wheel buttons should show some ohms of resistance to ground instead of open. (pressing the different buttons will register different resistances). Also try turning the lights on and see which gets power, adjust the dimmer and power should drop...

Steering wheel controls is more complex too - signal comes from steering wheel to radio, then if it's an HVAC signal, leaves radio and goes to HVAC head. So there is more than one wire associated with the steering wheel controls.
