I built one of these a few years ago... Used all the Renegade Hybrids stuff and the factory A/C compressor. It took a bit of work to make it right, but for $175 it gives you something to work with, without recreating the wheel.

I don't think I covered it much on my builds, but here is a link to my YouTube Channel, may be some helpful info in there for you -
