Holley Sniper wiring with Vintage Air

[SkeWest]

I have a 69 Camaro with a 383. I installed the Vintage Air system for cars without A/C. I'm now in the process of putting the Holley Sniper EFI on my car. The Sniper has optional connections for increasing the idle when the A/C kicks on and another to shut off the air at wide open throttle. Has anyone wired this combo? I called Vintage and they said most setups connect to the 12 volt power for the idle increase but the Holley instructions say to connect to a ground triggered A/C relay. I've tried calling Holley but have given up sitting on hold several times for 30 minutes. Thanks!
