Yeah, seems like a headache. Looking at specs and wiring diagrams (remembering I don't know what I'm talking about), it looks like there are similarities, but it's certainly different. The operating pressures are different, but maybe swapping the 3 way pressure switch would take care of that. Or maybe changing the auto A/C out for manual A/C would be a way to get past some of the differences.

And obviously going to a standalone and removing the factory ECU removes part of the system too. I guess the standalone can easily send an A/C request and idle up, but will the rest of the smarts play along?

I just don't know!
