High pressure shut off 1st, then you just ground the OE wire to the T-Stat and it'll work just fine.
The fresh door will move to recirc in Hi/Med, full cold, dash vents selected if I ground the OE pigtail, I was saying I really like the 'auto' fresh/recirc function, but you're right, its prob worth giving up a gimmicky feature. to avoid another compressor warranty replacement.
