Help! I need pmu power for the naza m

[DroneDude]

I got the Naza M flight controller today and need to figure out how to supply power through my esc to the PMU unit to power the LED. The esc im using is a 4 x 25A Brain Q esc. Where do I wire the PMU connections to the esc battery lead?

Do I solder them on at the base of the battery connection wires? In the middle? to the board?

Please help,
