1971 Slant-six ballast resistor ID

Hi guys

I have some questions about my ballast resistor.
Of course, I'm going to restore the connectors back to originals.

- Is this ballast resistor original, or at least correct for a 1971 Slant-six A-body?
- Is it in the correct location?
- Is it the correct holding down screw?
- Except the ballast resistor connectors, the wiring is original and untouched. Why do I have two dark blue wires and two brown wires? On the 1970 Dart engine compartiment wiring diagram (I don't have the 1971 diagram), there are two dark blue wires but only ONE brown wire.
