Both connectors are connected together is a series so they both seem to close the same circuit, looks like duplication. As you see there are too separate switches for park brake with one engaging and turning on the led and the other disengaging and turning off the led. Unlike that, seems like the auto hold activation/deactivation just happens when either bottom circuit is closed so not sure on the reason for duplication, once I realized that I didn't continue to make the second hole as it's not necessary to push both sides of the same switch for auto H
