Can someone reword what the SW plug is about?

from the clark site:

"HL tank already have power switch on battery cable path, so additional switch is no longer required, just to short pins in this port by jumper or connect to a switch cable and keep it switched on.

When higher current track motors are used, such as 400/480 motor,power switch on battery cable path will not be able to handle, connect a switch cable (for example, HL Smoke Unit Switch Cable) to this port as power switch."


I have stock motors right now.

Just to make sure, I should put a jumper there (like in the picture) because I don't have upgraded motors? Or just go ahead and connect the smoker's old switch to this?
