I found a power drill very useful to get the screws into the caps.
Here's what you need to finish the ends of the wires from the alligator clips:
First you cut the two headed alligator clip wire in half:
Then put about a quarter inch or half centimer of the end of the wire in one of the circle cut holes. Squeeze the wire strippers and pull them sideways to cut off the rubber casing -- without cutting the wire inside!:
You'll have the exposed wire ends:
Stick the ends into one of the holes in the terminal block:
And use a screwdriver to screw down the screw and smoosh the wire so that it's held tightly:
Do the same for the other side (strip the rubber off the end of the wire, then screw the wire into the second hole in the terminal block), and you're done!
