Not sure about the colors, but the 2 that plug onto male tab terminals near the center (bearing cap) attach to the brushes. They go to the regulator on the firewall, silver box with (I believe) a 3 wire plug held on by a clip. There is also the output wire which is a much bigger wire that goes to battery positive

70 and later, large black wire (+) to the large bolt terminal on the bottom side, green to the field on top and blue to the terminal between the 2. On 69 earlier, Black to the large bolt termnal and green on the top.
