I will be wiring up 2 humminbird helix 12s, garmin 106ultra and livescope 34. going run everything back to the battery. will be using 10 gauge wire. 2 graphs on bow and 1 on console. my plan is to run everything back to the battery to a on and off switch. will be using inline fuses. are those inline fuses from sea clear worth it? im considering using those solder seal connectors for my install. does this sound like a solid plan? what else do I need to buy besides wire and the switch? are those solder seal connectors step down like 10-12? thanks
