As I recall, this is where they stopped featuring proper power on pads. There is a test post on the back of the board, which you could use but I wager the easiest place to accomplish this is to use a resistor and a capacitor near the Touch ID and Audio connectors. This is on the same line as the Power On Pads from previous generations.It references SMC_ONOFF_L. This means it turns the System Management Controller on or off when the voltage is low (shorted to ground).
