Dash Power Feed Confusion

Thank you @67Dart273 and @Mattax. Those diagrams are making a lot more sense with your explanations. I had the wiring diagrams in my Haynes manual for the car but when looking at those I always find it confusing with the diagrams being so busy. As Mattax mentioned the car is a 74 Dart Sport with a 225 and a904. As far as I can tell, the last diagram that Mattax posted makes the most sense. The other wires on the black ammeter side run to somewhere under the dash, possibly fuse panel, but I havent investigated at this point. The 2 brown wires did plug directly into the 2 black ones, I was just confused as to why. There is 1 brown larger wire running from the alternator output and is welded to both of those smaller brown connections up near where they enter through the firewall. Those diagrams helped me clear a lot of this up.
