The wiring can appear confusing, don't be alarmed. It's quite easy, and absolutely necessary for proper flight.

The 4 bottom connectors receive the motor power cables that are Red/Yellow wire pairs from each motor. Counting the sockets 1-4 from left to right.

Front Right motor connects to socket 1.

Front Left motor connects to socket 2.

Rear Left motor connects to socket 3.

Rear Right motor connects to socket 4.

The Red/Green wire pairs from each motor power the LED to that branch, they connect to 4 of 6 sockets on the top of the receiving board. There is no sequence required.

The headlight LED, and underside LED bars connect to the remaining 2 sockets on the top of the receiving board. Again, no sequence is required. All LED Red/Black and Red/Green wire pairs connect to top of the receiving board.
