Wiring question

A fused busbar is the only way to go IMHO. A little more wire in the bundle, but much easier to isolate and troubleshoot should the need arise. I found that fuses on the console next to the switch tend to corrode a lot faster than protected fuses. Make sure you keep a dry record somewhere of which terminal feeds which unit. I also "bus- barred" all my ground leads individually. One open ground on a daisy chain and lots of stuff quits working! Remember, anywhere two pieces of wire come together open to the air is a corrosion site waiting to happen. A well protected busbar coated lightly with a good corrosion preventative can help eliminate a lot of that. Just MHO
