I think the intent is to cut off whatever connector is on the hot end fan and hardwire it. Many of us have added a connector to make disassembly of the extruder easier, but it increases the risk that the connector is apart for some reason and the fan isn't running when you need it to.

On the heat bed relay wiring, are you asking what wire gauge to use? It's a pretty good place to use some hefty wire to minimize the voltage drop through it, leaving more room for the smaller gauge wire typically provided with the heat beds. I used some #14 stranded wire I had for my smaller 8-inch heat bed.
