Rv 12v grounding question
Hi everyone,
I'm hooking up a new A/C, thermostat and control box for my live in travel trailer.
Really different from everything else I have worked on. It's a Dometic system and they
have there own way everything is done. Have to use their t-stat and control box.
Where I need your help:
I took the schematic and drew out a wiring diagram where I could understand it and uploaded
it, then sent the link to the head tech where I bought everything and asked him to look at it.
Here is that link:

And here is his reply:
"I have looked at this and you have to connect a 12v ground signal to the wire on the number 2 connection . The control box will not send the ground out to the t-stat.
Thank you"
So... as you can see from my diagram, I just show a normal -12v lead. He is saying something about 12v ground.
What does he mean that is different than what I have drawn?
Thank you kindly for you expert help,
John
