If the car has daytime running lights (or is 2009 or newer), then pin 13 is a ground, switched by the headlight switch (so, you would use pin 13 as your LED ground and would connect the +12 wire for the LEDs to a 12 volt source).

If the car is 2008 or older and does not have DRLs, then Pin #13 is not a switched ground, but instead is a +12V feed which is switched at Pin 10 (the wire to the left of the Pink one) (which will be green instead of white with a black strip). So, on this vintage, you would connect the + wire for the LEDs to the green wire in pin 10 and the - wire of the LEDs to a chassis ground.

hi! If I want to turn something on with the flash or high beams od the headlight, were I had to connect the + and - wires of my 12v circuit? I wanna do this because I want to open my garage goor with the opener activated when I flash my headlights.

Maybe I have to tap de + with the Pin 9 and the - at the Pin 11?
