That seems to be general concensus of a good way to wire it from all else I've read; I also tried blue/white to blue/black and a ton of other combinations, but my FFing fans will not turn on at all. If I hardwire them to the battery, they all start fine, but any combination of these existing wires does not work at all
Again, I've checked all the relays and fuses, all are in proper working order.
