Be Cool with dual Fan setup

[Tom Vogel]

Ive got a large Be Cool radiator that came with a dual fan setup. The system came with 2 relays and 2 wiring diagrams. One relay and diagram was a SPAL; it showed the possibility of wiring the two relay so both fans would come on together always. The other relay with digram was Be Cool, it showed in the wiring diagram that the relays should be wired so that only one fan would be wired through the temp switch. The other relay would be wired to go on through the AC trinary switch and an optional over ride switch for possible need in say traffic or whatever. Is there some reason the relays should be seperate , or can I wire them so the ground switchs ( temp switch; trinary switch, and overide switch wired in tandem) allow for both fans to come on any time the temp switch senses 195? I hope this makes sense...
