Fuse #9 4.3 4X4

A trick you can try is to replace the fuse with a pair of spade terminals, then use a pair of small jumper wires to connect them to a 12 volt light bulb. A brake light bulb works well. Rather than blowing lots of fuses, the bulb will just be full brightness when the circuit is turned on and the short is present. Now you can unplug things and move harnesses around to see what makes the bulb go out or dim. When it does, you removed the short.
