For now, I went ahead & wired in a relay & the A/C works GREAT, 45 degrees out of the center vent, 98 degrees ambient, Head Pressure never got over 250, Low Speed Fans always on, High Speed cycling on & off. Not crazy about not having over pressure protection but, As long as I don't lose a Fan or a Relay.....I should be OK.
Hopefully I'll have mine running soon and let you know if it works.
