funny you should mention that but i have recentlt done similar with my yamato.
yes there are 4 motors here, but wiring is in two destinct pairs, Inboard and Outboard.
you will also notice that I have used 240v 13a cable using the two main colours.
each of the esc's are wired in parrellel too off the main battery. the choc-block in 0018 is the key to it all. wired up yellow then blue / blue then yellow, which one is inboard and which one is outboard I can remember, as I didnt pay that much attention to it, I wired them up one by one, taking the in-board wires linking the two brown wires together and feeding them to the yellow wire of the esc, then repeating that with the blue wires of the esc.
this was repeated for the two outboard motors in IDENTICAL method, the only difference being that the blue and yellow wires were rotated round in the choc bloc. despite this, yellow still went to brown, and blue still went to blue
