You need to test out what the wires on your LEDs do.
You have three wires: blue, red and black. I assume black is ground. When the red wire is connected to a power source, what happens to the LED? When the blue wire is connected to a power source, what happens to the LED? You'll also have to test the wires on the plug with a test light or probe. Also test when the dome light is in the ON, as well as the DOOR position. From there, you can determine how to hook up your LED. |

That's not what I meant.
You need to use a test light and/or probe and tap into your plug to find out what wires are hot and what ones are ground. Then on your LED, test the wires to see what happens to the LED when connected to the red or blue wires. If your LEDs came with an information sheet, that would help as well. |

@Eduardo_mty, did you manage to get this working? I've got a MkIII Yaris in Australia and trying to do something similar to what you're doing, by tapping the front map light assembly, but not having much luck...
