Windstar fan question

[jdalexa84]

I have read several threads about wiring these fans and I have learned that they are not 2 speed fans without the resistor. I am ok with that I will just use the one speed.
My question is if I use 2 relays one connected to one of the positive wires for pcm control (LS swap) and another relay to the other positive for the ac to trigger will that work? I am probably overthinking this. On the Windstar harness both positive wires are connected to each other.
