Similar to the headers, solder 'tack' one of the pins to keep the component in place, turn the board over and check that the terminal block is straight and flush with the PCB before soldering all three pins.

Finally, it's time to add the relay -- it can only go in one way -- and solder it in place:

Last step! Decide how you would like to control the Simple Relay Shield, and wire a jumper to the control input.
 
 
 
 
The default configuration is to control the relay through pin Digital 4 (D4).  If you would like to control it that way, then install the zero-ohm jumper wire (which looks like a resistor with one black stripe) in the location marked JP, by the transistor:

If, instead, you would like to control it from a different signal line, connect the zero-ohm jumper wire (or a different wire of your choosing) from the side of location JP marked by the black diamond (♦) to the signal source.  For example, you could wire up the Simple Relay Shield to line Digital 7 (D7) by soldering the jumper as follows:
