I used one 40 amp relay for each fan with 10 g wiring to the battery and fans. I also used electric grease on each contact point to reduce heat from arcing.
Run three, here's the wiring diagram.

Nice, easy to read, diagram. Thanks. But why run three relays...versus two?
Also, who sells good quality pigtail harnesses, for Bosch relays? thanx
It uses 3 to tie both together and control both fans speed, 2 would only run 1 fan at high speed only, and the other at low speed only. This way shows that when the low speed fan is engaged, it turns on the other one also and vice versa. Please correct me if Im wrong.
I have ls1 fans... I have 2 relays, but 1 switch, both come on full blast when I flip switch (which realistically is only when I'm sitting in traffic or have AC on)
On buddy's truck, 1 is always on, he has a switch for the 2nd.
Hey bud did those fans bolt right up to ur radiator?Quote:

Cool. I got the set from an 05 6.0 at a junkyard for $125. They are 15" dual fans. Also got the radiator brnad new also from the 6.0 and it cools like a mutha. I can throw a rag in front of the grille and it will suck it and hold it.
Good info. They say to run a 10 gauge supply wire to your fans. But the relay connector/pigtails that I find, all have very small gauge wires coming out of them. Wimpy stuff. Anyone know where to get them with larger gauge wires??? thanks
