Notes:
Don Thompson warns to not plug DCC decoders into this engine without dealing with the headlights, first. The headlights are 5-volt bulbs, and they will blow as soon as the decoder receives power (usually around 12 volts).
One option is to consider replacing them with LEDs and a matching resistor. The same applies to class lights, numberboards, and Mars lights, as applicable.
Don Thompson recalls that the wiring for the MARS light is there for single-headlight models. Note that the F7 models had the MARS light at the top and the main headlight at the bottom, as per the prototype, for dual-headlight models. This was an error discovered during the F3 production run and fixed for the F7 models.
