Image #1: as pointed out, the additional instruments connector, which feeds power and signals to the auxillary fuel and oil gauges. Although it resembles a Molex connector, it is not a Moxel connector. You will have to remove the yellow socket from the connector shell to access the fuel sender signal.
Image #2: is the combination switch. The pin numbering is printed on the 9-pin shell if you search for it with a magnifying glass. The picture below shows the male connector end.

You'll notice the three keyed bumps on the lowest edge. The pin on the left is Pin1. To its right is Pin2 and the next most right pin is pin3. Moving to the next row upwards, pin4 is on the left, and so on. Reference a schematic diagram to determine the wires that represent the start switch wires you are after.
