MK2a Heating bed wiring question

[Zorce]

Was never found nor was it on the heatbed. I ended up getting one off ebay for $15.

Also I am finally getting around to finishing the structure side of it and your instructions just say attach the LCD board.
No instructions on how it attaches at all. There are also triangle parts that look like attach to the lcd acrylic plate but absolutely nothing in the instructions about them or how they attach.
Also does the lcd screen not come with a knob? I looked through what is left of my kit and see no knob to stick on it.

I hope the electronics part is not as vague as the structural build was.

Is it clear?
