	So, to add the connectors, we first have to separate them from the break-away header row. You can do this with a scalpel or side cutters. You will need nine single-pin connectors and one 3-pin connector. You can also completely remove the plastic around them if you want. Now put one by one into the pcb, and solder them. You do not have to cut away any excess wire afterwards. You may however try to reheat some solder joints and wiggle on them, if the connectors are not straight.

	Now add the column and plane connectors to CONN1 to CONN10. This step is optional and it is probably the most annoying part of this PCB, but you should think twice before you skip it: It allows you to disconnect and reconnect your cube without expensive equipment. And do repairs on it which may not be possible while it is connected. But it's your choice - skipping this step does not have any other significant effect.

	If you are supplying your own LEDs or did not get matching resistors for any other reason, you have to pay attention: The ideal column resistors should be chosen for each LED color separately. You are always on the safe side, if you choose a high value, but then your cube may not be as bright as you want it to be. If you are interested in this, read [[LED Cube/Column Resistors in Detail]].
