Soldering and such...

EDIT: this project is just 2 simple circuits.
•Circuit 1 is just an infrared light emitting diode (LED) and a single voltage drop resistor.
•Circuit 2 is a regular LED for lighting (can be any color you want) and it's voltage drop resistor. The LED is bypassed by the DETECTOR when infrared light is present. It's that simple

.................................................. ......................

Circuit 1 - IR Emitter
• D1 - 1.2-2V, 25-100mA (wavelength must match the detector that you choose)
• R1 - 470 Ohm, 1 Watt resistor
Simply solder a resistor to either leg of the emitter and wires to both the resistor and the other leg. Just make sure to keep them straight. The anode is (+) and the cathode is (-)**. Cover the resistor and connections with shrink tubing. Make sure you keep your wires straight.

**[You can get this info from the package, but you can also tell by looking; the anode leg is longer and if you can see inside the emitter (a clear emitter from an old tv remote, for example), the (-) cathode is the side that is connected to what looks like a tiny satellite dish and the anode (+) is connected to a tiny wire that runs to the center of the tiny dish.]

Cut grooves for wires...EDIT:If you keep the wiring and components tucked forward and below the edge of the shelfs lip like I have here, no modification to the dash frame slot is needed because there is a space created there when the shelf is fully inserted.

Circuit 2 - Lighting LED
• D2, 3, 4 - LEDs of YOUR choosing
• R2 - Resistor (Value depends on D2, 3, 4)

• Q1 - IR Detector, 3-5V, 30-100mA.
(Collector is connected directly to the (+) Anode of the lighting LEDs)


***All (-)Grounds are common.
Solder in main power wires for (+) and (-) and power from a switched source (stereo or dash lights). Solder in an in-line 1A fuse for safety.
I connected mine to the ring light on the cig lighter. This way, the circuit is only active when the dash lights are on.
Since the circuit only draws 22mA, it's not going to affect what you wire it in to.
