I bought a bunch of 20 amp @ 125vac switches with screw terminals from Hosfelt Electronics at $1.25 each and I got a couple 12 position ATC fuse blocks from Wiring Products.com for $24.00 each. The wire I got locally and the rest of the stuff I either scrounged or had in my parts drawers. Each circuit has an LED indicator which won't light if it's fuse is blown. The switches and LED's are all mounted on this 1/4" teak plywood face panel. Power will come in through the fuse blocks that will be mounted in the same box directly below the switches. Power out will go through a terminal strip nearby in the engine box then to the devices.
