In case you're curious about that unpopulated part "missing" from the board, if you were to place a jumper or say 10 Ohm resistor there instead, it would tell the module to ignore the condition of GP #1 and show the dash light anyway (still evaluating GP 2 through 6, and temperature sensitive timer).

You could add the missing part in combination with the suggested mod in this thread, they can be used in combination.

But I couldn't see the value in omitting GP 1 from all the fun of having it separately evaluated by the GPR.
