I find it useful to include connectors in the wiring diagram because then you can break it down into 3 separate areas; battery, ESC and the link.

Battery has a connector (male I think)
I wire up both ESCs to a single connector (female) with the LED across the 2 connector pins.

So now I can test the ESCs, motors, LED etc by plugging the battery connector into the ESC connector.

In the meantime you can now create the removable link / fuse circuit with 2 connectors. The negative pins are connected together via a simple wire whilst the positive line is routed through the fuse and removable link.

You then just slot this fuse circuit between the battery and ESC and you are all legal.
