This is probably one of the easiest steps! All you are doing is soldering wires to the 4 groups.

I used some pieces of wire about 6 in long. They don't have to be different colors but it can be helpful if anything goes wrong & you need to debug the circuit. You don't need some header pins, but if you want some feel free to use them.
