Hook It All Up
Carefully flip your board over and start bending your component leads toward their respective springs. If you have any polar parts, like LEDs, make sure you've labeled the spring connectors accordingly and connect them the way you've indicated on the front.
Some components will reach the springs on their own, but others will need a short length of wire. Even if a lead will hold itself in place under the spring, I like to add a bit of solder just to ensure a solid connection.
