KK Mini wiring help needed

[Raven]

Hi Guys, Need some help here. Am getting very frustrated with this board due to the lack of layout plan.
Here's what I have got. Seriously I cant even confirm if my wires to the ESC and RX is correct as there are totally no clue to it. Here's my wiring diagram.

1 PIN ROW SIDE
RX ch1 => AIL(1 wire)
RX ch2 => ELE(1 wire)
RX ch3 => THR(3 wire I know this is weird but please read below)
RX ch4 => RUD(1 wire)
RX ch5 => AUX(1 wire)

3 PIN ROW SIDE
ESC1 => M1(1 wire)
ESC2 => M2(1 wire)
ESC3 => M3(1 wire)
ESC4 => M4(3 wire I know this is weird but please read below)

Its weird, I have power going to my esc but it does not power up the board.
Power does not reach my RX as well.
But if I have a esc plug directly on the 1PIN ROW(last 3 pin THR, V , GND)Board will power up nicely.
Am I doing something wrong here?If I plug an external 2S to my RX, the power will reach the KK mini and power it up but then it will only show a blank screen. Can anyone advice on this?

My RX is OrangeRX TFR8S.
Thanks in advance. AL

Try plugging in the esc with bec (power supply) to M1. Typical KK boards only use M1 to power up the board.. Let us know how it goes

Thanks Guys for the help. Indeed the board only feed from M1.
Seriously, they really need to come out with a manual or work instruction.

Thanks!!!
