heater GND

heater gnd is where the switching is done, so unless you want to switch everything when the heater does, then no. (you dont)

@bearer makes sense. More ground cables it is then

@bearer Looking at the schematic the fans are all powered from V_FAN ... at least there it should be possible to use a single wire on the positive connection?

Fans and heaters are switched on the ground side. But you can have one common supply cable, ie, 24V or whatever you got. If you use a special supply for the fans they would need their own cable.

No idea how to mark this as solved. But ... solved. Thanks.
