Hmm, you'll need two relays unless you want it to run all the time on low speed.



There are three wires leading into the wiring harness for the fans.
One is to ground, the second is for low speed and the third is for high speed.
Both fans run together.
If I use two relays, will I also need to run two switches? Or can I use a double throw switch to move between low and high?

My life is none of your business.
