Taillight wires/Engine Fan

I just bought a 09 700 Grizzly, and the tail?brake light didn’t work. I pulled the storage box out, and all the wires were unplugged, I matched up colors and got the brake, and tail light working. Then I discovered my engine fan is not coming on, there are still two wires by the taillight that are not connected to anything. I read somewhere that the engine fan has a fuze wired into this location, any info on this would really help.
