LS Swap - dual fan wiring

Been reading posts and articles and of course LT1swap website. Not finding what I am looking for... Can you guys help?

I have dual fans that came with my radiator. They are SINGLE speed fans. The following diagrams on LT1swap.com shows how to wire up either a single speed fan(singular), or dual speed fan(singular).

My question is how do I wire up DUAL fans that are single speed each? My PCM wiring has low and high speed wires to hook up. Do I just choose the high speed from PCM only?






My PCM wiring via LT1swap.com shows I have a low speed and high speed wires to use.
BLUE/GREEN wire harness connectors - 2005 Harness
Is this correct that these are low speed high speed? Or is it just FAN1 and FAN2??
