the two very thick wires are to make sure the starter doesn't crank in any gear other than park or neutral.
dark blue wire is hot with the ignition key in the run position, light green runs to reverse lights and electrically connects to the dark blue wire when gear selector is in reverse.
there are two other small guage wires on the switch, one is a ground, the other is an input to the ecm. both wires connect electrically with the gear selector in park/neutral.
