Hi Prostreet,

I let the Vintage air controller request the AC directly to the AC clutch. The high pressure switch is wired to the ECM just by the factory wiring. The ECM is happy to control the high pressure with the fans even though it didn't request the AC. I have a low pressure switch but it is not wired in. Since the factory didn't use one it must be ok.

If I didn't answer your question, ping me again.

You should put the low pressure switch in series with the clutch, that way you will know when it is low before your compressor packs it in.

Thanks IIGW,

I'm reliving it now, I'm installing one in my 69 Chevelle.

Still working good after all these years. Went to the Home Depot in the old truck today to buy lumber, needed the AC 90+ degrees.
