Hey Jason,
I’m going to be doing a video about all that pretty soon For my YouTube channel.
In the meantime I hand drew a wire diagram I can send to an email address that would probably answer some of your concerns.

How do I find you on YouTube? I too am very interested in this. I think I have it correct, but would like to see a visual to be sure.....
