Taurus fan wiring question

When using the taurus fan, can both the low speed and high speed be powered at the same time? I am unsure how to wire in the high speed while shutting off the low side in the process.

Any ideas? I have 3 of them needing to be installed between the truck, the jeep, and the LS1 miata
 
This what you are talking about?

If you want the low speed to run you must run it through the 87a terminal of the relay so it is disabled when the high speed kicks in. I have a more detailed drawing showing two fan speeds. PM me if you want that one.

The truck only has a mechanical fan, but has AC (1999 Cummins)

I will be using a switch set at 180 degrees and one set at 207 degrees
