Location: 31 | I settled on a 25 amp fuse between the battery and dash switch. I like the location and light-on feature of that particular switch, but it was a little bright at night so I just covered up most of the blue light with a piece of wire tape.
I used about 100’ of marine grade wire to hook up 4 graph locations, 3-D Lowrance module, stereo, two way radio, and 2 project Xs. The dash switch also eliminates the need to switch off the boats master switch, which is inconveniently located in a rear hatch. Having the ability to be 100% sure all the electronics are off but still being able to operate the motor trims and jack plate makes it that much easier at the end of a long day.
It took some time to wire this up, but I like the accessibility and knowing where everything is in case there's a problem. I really hate those pesky in-line fuses, and stacks of wires on the battery. The fuse block is expandable, and it also makes it easier to swap out future electronics.
I remember having to return the first fuse block I ordered because it didn't have a dedicated ground, which I thought was weird. I had to shop around to find one with a positive and negative like the one pictured so it's completely isolated to the designated accessory battery. Good Luck!
