And you can check if the gps board get power ( voltage )
put needles beside the wires and check with the voltmeter or there is power
I got this result
red - brown 5.50 volt
red - yellow 1 2.47 volt
red - yellow 2 2.35 volt
yellow 1 - yellow 2 0.11 volt
yellow 1 - brown 3.04 volt
yellow 2 - brown 3.15 volt
Watch out that you do not cause a short circuit between the needles or you wil fry the naza or/and gps
