Default A/C Binary Switch with Holley?

So, i'm trying to get the a/c going in my wife's '99 Camaro with a Terminator X in it. I bought a separate harness that's setup to wire it all up, but I can't find a binary switch to replace the factory sensor that fits and screws onto the stock line in it's place. Anyone have a part number for me for one that will work? Thanks for any help!

Contact vintage air. They also have tertiary switch for extra fans.

BTW: they have some pretty good videos and diagrams showing how to wire in the switch.

Why not use the stock pressure sensor? You can program a custom 5v input to the Terminator X, then program an output to ground the compressor relay.
