I picked this up in a JY a few months ago just to check it out, but after feeling how hot the heater box gets just letting the truck idle a few times, I installed it & connected the vacuum line directly to the manifold to keep it in BYPASS with the engine running. When winter rolls around, I'll disconnect it.
