Take that relay out of there...In insert your motor where it says lamp use a switch,single pole double throw and you're going to need the associated resistor value(not shown) with your LED depending on what color it is. Because different color LEDs have different forward voltage (Vf) so 9 volts minus the forward voltage of the LED then then divide that to play it safe say 0.01 amps that'll give you the resistance needed.
You will be applying 10 milliamps to your LED.
If you want to use a relay I can show you on a schematic but you have to know how to read schematics I can't do it with pictures on a breadboard sorry....
