We had a thread maybe a couple of years ago on how to rig a A/C cut out but
I'm damned if I can find it- checked the archives, my personal stash... I
don't doubt that some other thread heading got hijacked into an a/c
discussion and I can't find it because it's called 'which porta-potti works
best...' or some such crap.
Maybe Sisler remembers this... anyway the idea was that there are some
vehicles out there that use a vacuum (or maybe it's lack-of-vacuum) switch
of some kind that cuts out the compressor when the throttle is open far
enough. Unfortunately that's about all I remember.

Cya,
