LED Mod Kit Installation Instructions Thank you for your purchase of the Modiify LED Mod Kit for Xbox 360 Controllers. We are sure you will enjoy all the benefits it has to bring. This short guide is intended to get you started with your installation and how to fit all components into the controller. Visit www.modiify.com for the most up-to-date products, videos and news including tutorials of the famous ARBITER II RapidFire Controller in action. Opening the Controller Grab yourself a Torx T-8 Security Screwdriver. Remove the battery pack and remove all 7 screws from the back of the controller (one hidden in the center underneath the white bar code in the battery compartment. Drilling the ABXY and Guide buttons In order to fit in the LEDs you first need to drill out the buttons. Remove the buttons from the controller and take the ABXY and Guide buttons. On the back of the guide button you will have a cross section running right the way down, and on the ABXY buttons you will have 4 while poles. These make contact with the button pad to trigger a button press, so you need to make sure your LED or hot glue later on is positioned back to this height. Take a drill that is the closest size to the hole of the button, or just slightly smaller so it can be wriggled around. Secure the buttons in place in a vice or similar before doing this or grip VERY tightly with your fingers but this isn’t recommended. Go SLOWLY and keep checking your depth regularly. Do not go too far in as the letters or X will be revealed and this can let too much light through and cause pin-spots when lit up. The image on the left is the ideal depth, and the one on the right is a little too far. Fitting the LEDs Once you have the holes you are ready to insert the LEDs. In one of your bags you will find 5 LEDs. Four of them are white for the ABXY buttons, and the 5th is the color of your choice for the guide button. Test which LED is which color either by obvious color or using a 3V cell battery. The longer lead on the LED is the positive, and the shorter is the negative. Attached the cell batteries + to the long leg and – to the short leg. Insert the LEDs into the button holes to test their fit. Remember we originally said that the poles that we just drilled out need restoring in order for the button to make contact with the pad – well this is where the LED comes in. Push the LED into the button and take note of the point at which the legs of the LED are at the height of the poles before you drilled them out. Now remove the LED and bend the legs 90 degrees at that point, solder the red (+) and black (-) wire found in the other bag to the legs right on the bend, then snip off the excess legs. Re-insert the LED and once you are happy with its position and that the small flat you have now created with the 90 degree bend is the same height as the original poles, you can optionally hot-glue them into place. If you think the flat on the leg isn’t high enough, you can use the hot-glue to make a flat pad at the same height as the original poles instead. The wire is easily passed out of one of the slots at the side of the buttons. Repeat this for all LEDs. The length of wires for the ABXY buttons is about 3 inches, and for the Dome just 2 inches. Joining them all together Place all of the buttons back into the controller. Now position the leads so that they all come out of a button slot and then find their way to just above the Start button as you look down on them (left of guide button). Now solder all red leads together and all black leads together. Finally take the remaining red and black wire you have left and solder the red to the red joint and black to the black joint. What you have done there is turned 5 red wires into one red wire to work with, and the same with the black wire. Tuck away these joints inside the hollow of the controller shell and just leave the two red and black leads coming up out of the top of the controller. Replace the grey contact pad and then the circuit board so that the buttons are back in place and you have just the red and black wire making their way to the back of this circuit board. Installing the Transistor In with the LEDs came a resistor and an NPN transistor. These are used to ensure the LEDs are only on when the controller is turned on. Your transistor looks like the image to the right. Note that one side is round and the other is flat. Solder one leg of the resistor to the center leg of the transistor (feel free to bend the legs out and trim them down) and the other side of the resistor to TP8 on the circuit board. This is located as you look at the board to the top right shown in the image below. Now solder the black lead to the left pin of the transistor when it has its flat face pointing down. Solder the red lead coming from the buttons we did earlier to the battery + solder pad. And finally use the third color wire to solder from the remaining right-hand pin of the transistor to TP22. Before rebuilding the controller ensure that the transistor and resistor are covered in electrical tape or other so they cannot contact the board. Installing the Player LEDs The final part to the install is to quite simply remove the old 0603 LEDs and solder on the new ones. The LEDs are located on the same side of the circuit board we were just working on. Take a soldering iron with a bit of solder and once up to temperature place the iron on one side of one of the LEDs for 2 seconds, then quickly move it to the other side and continue to repeat until the LED slides off. Do not leave the iron on too long else you can burn or lift the pads. Once the LEDs are off, the final bag in the kit contains the LEDs to replace with. Solder the new LEDs in place with a little solder. It is recommended to use tweezers to hold them as they are very small. The LEDs need soldering a specific way around. Because every LED color and batch has different marking every kit comes with a 5th LED for testing. Take a 3V power source (cell battery is ideal) and solder some wire to positive and negative. Now touch the positive and negative wire ends to the pads of the LED one way around and then the other. Only one way should light up. Whichever way that is remember which point is positive and which is negative and then it is time to solder them in. On the circuit board, negative is the pad that has a dot or line in white as seem in the image to the right. So the negative side of the LED should go on that pad.
