Is this the right ubec for a flight controllers kk2

[Jazzz]

I';ve got 20 amp littleBee with no ubec
I';ve never used a ubec do you wire it to the power distribution boured +- signal wire not used on input
Not sure what to do with the out put wires apart from may be splice them in to motor 1 wire from the esc to the flight
Control is this the right way .

Input wires to pdb, output wires replace power wires for motor 1, if you';ve only powered motor 1.
I think that the power wires on kk fc';s  have common + and - so as long as you get polarity right all should be good.
