I picked up a heat bed kit off amazon, it has the thermistor and power cables. But there were no small parts for the 3 spaces. The heat bed I got from the shop here has something soldered.
What belongs in the 3 spaces circled in red?
Isn’t that where an LED and current limiting resistor can go if you want to have an indication when the heated bed is being driven by the controller?
It’s optional.

Thanks. I remember it lighting up now. Yea, it’s not worth the effort to solder that, will be covered up with insulation anyways.
