Rawze adrino setup

[kozakvod]

I have a guy that build mine, and after reading through Rawze's thread on this I'm still WAY confused on how the thing gets wired in, is it tied into the existing system, what turns it on and off or is that the main AC switch, how does it connect to the compressor, etc.?

I've had a major ongoing issue with my AC that I have to get fixed and I see this is probably my only option and I will NOT let the stealership lay another hand on my truck ever again. Soooo....

Can anyone offer another link to answer these questions or just the answers.
