Alternator Wire Connections

I'm restoring a 1974 Fiberform Cuddy and I have just installed a new 351w. I I'm the process of connecting all the wiring. I currently trying to wire the alternator but the problem I'm having identifying where the four wires wires connect. I have orange 10 gauge that I'm sure goes to the battery connection, marked with a + sign. The other 3 wires are black, brown, and green. There only one other marked connection marked AUX and the other two wires connections aren't marked. I know either the brown or green wire connects to the Field and I'm not sure where the other wire connects. Both the green and brown wires go back to the voltage regulator which does not have any markings on it. I haven't been able to find a wiring schematic with these wire colors.
