Default Vintage Air, Trinary switch wiring, PSI harness

I'm sure this has been covered 1000 times already, but I am trying to figure out how to wire the trinary switch for my VA system. I have a PSI harness with 2 wires for the fans, but how do I incorporate the trinary switch to turn on one of the fans without interrupting the ECM? this is an LS3 swap, Griffin Radiator, twin fans with PSI harness.

Thanks for any help that you can provide...did I mention that I hate wiring!
