I've always installed as shown in the 21-12a figure posted above. Had a Porsche dealer tech point that out to me 25+ years ago, saying it goes in backwards to how most people want to install it.
I did remove one on a street car one time, because I thought it might be failing (turbo water pump was running constantly, turned out to be a bad temp sensor). Car would not get up to temp in moderately cool weather, not warm enough to blow heat when wanted/needed in the cabin. So I'd recommend running the turbo therm on a street car, unless in extreme hot climate conditions.
I have run without one on my track car, because I'm always racing in warm weather and running the car hard, so no worry about the car not warming up.

FWIW the turbo thermostat never made a difference in engine or cabin temperature back when I was running the original 2.5 8V engine. I would suggest the OP, and anyone using a dual ball bearing turbo, to get rid of it.
