Fuse Block Schematic HELPPP!

1971 Dart, L6, auto, 2Dr- need diagram for fuse block. Brake lights INOP but turn signals, hazards, and reverse OK. Temp and fuel gauge INOP but Speedo and Alternator gauge OK. I know about the "instrument cluster voltage regulator" that controls fuel and temp gauge so I've yet to check that (don't know how yet). There are about 3-4 wires from fuse block that lead to loose wires and behind cluster there are many electrical plugs not connected. ANY IDEAS OR HELP WILL BE APPRECIATED. THANKS!
