Question regarding HE1, HE0 and H-BED pinout

[arhodiewithsoul]

As per the title, please could you clarify if the pins are low side switching or high side?

To ask another way:

• FAN2 -
  (PB1) is on the ( - ) indicating low side switching. The ( - ) wire is the one carrying the switching signal.

H-BED (PA0), HE0 (PE5), HE1 (PB0) are all marked between the terminals. Is the switching signal carried by the ( - ) pole or the ( + ) pole?

Thank you

If I read this image correctly, it indicates that 'HE2' or Heater2 on pin (PB0) is high side switching. It carries the signal on the ( + ) wire. Can you confirm that this is correct.

Also, the silkscreen and pinout guide both show pin PB0 as HE1 and pin PE5 as HE0. This is somewhat confusing and conflicts with your schematic (SCH) file. It would help if you used the same pin codes/ pin names throughout. It would also help if you aligned the pin name with the active terminal - using FAN2 (PB1) as a helpful example.
