This jpeg was posted a few months ago. I don't know if it will help much, maybe you can sort it out by a process of elimination.

I am trying to install a new head unit and I do not have a wiring diagram for the orignal harness. I need to know which wire is:
1. Ground
2. 12V Continuous
3. 12V switched
I think I already know what the 2nd and 3rd ones are but not the first one. I would like to know all three to make sure. Thank You
