Step 6LED setup
Find the caps lock LED and locate the positive and negative pins on the circuit board. You can do this by either using the diode checker on your handy multi-meter or by using a small battery and a couple wires to to light it up.
Fish the wires from the musical element up through the keyboard and to the LED.
Solder the wire from the center transistor pin to the positive LED pin and the other wire to the negative pin. (the image is from an ergo keyboard)
If the LED is not attached to the circuit board (as in the image) you can solder the wires straight to it. Be quick to prevent overheating the LED. However, most keyboards have the LEDs attached to a circuit board. In that case solder the wires to the same point on the bottom of the board where the LED is soldered to.
