Do: Land the two ferruled heater leads in the HE0 screw terminal. Polarity does not matter on a resistive heater. Tighten firmly with the 2.5 mm slot-head driver and tug-test each lead.
Check
No copper visible outside the ferrule; neither lead pulls out; the two terminals cannot touch.
What you're looking at
HE0 is the heater output, the highest-current thing on this board, hence a screw terminal and not a plug. A cartridge heater is a plain resistor, so polarity is irrelevant; what matters is that no stray strand escapes the ferrule and bridges the terminals.
