Step 1: Parts and Tools
Step 2: Wiring the LED's
Resistance in ohms(R) = ([power supply voltage(Vs) - LED voltage drop(Vf))
LED current rating(If)
* Power supply voltage (Vs) is the voltage of the power supply e.g. a 9 volt battery.
* LED voltage drop (Vf) is the voltage drop across the LED (typically about 1.8 - 3.3 volts; this varies by the color of the LED) 1.8 volts for red and its gets higher as the spectrum increases to 3.3 volts for blue.
* LED current rating (If) is the manufacturer rating of the LED (usually given in milliamperes such as 20 mA)
or you can simply do a search for "LED calculator" and pick one. Orrrrr you can use Led Calculator from LedCalculator.net. The last picture shows how I routed the wires around the outside of the fan shroud.
Step 3: Testing the Connections
Step 4: Ready to Install
Hope you all find this useful and thanks for lQQking!
