Added #12 black wire. I had #12 green wire and thought I only needed one wire. So after much deliberation, research, and reading responses to a question I posted on Skoolie.net. I decided to run the black wire with my green wire to connect my ground to the ground post.

I am going to use the black as the HOT wire and the green as the GROUND wire. If I had to do it over again I would have used black and white wire so as not to confuse myself later or anyone else that may have to work on the 12v wiring.

 I also cleaned up a bit by zip tying the wires together. 

 When doing research on the 12v wiring I found that I needed to put in wire protectors so I did not put a nail through my wires or my water lines. Good thing I saw that. The silver metal plates you see on the wood in the first two pics, are the wire protectors. They are med gauge metal that will not let me drive a nail into the wire. 

 See the little love note my wife put in my bus?

Hopefully I will be able to work on it some more tomorrow evening.
