On the headlight stalk connector (remove the bottom steering column cover to get to it), Pin #13 is the switched wire for the taillights (which turns on with with both the high and low beams).

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?

If you have a 2005, then yours is a fist gen, so the headlight wiring will be different than the second gen connector pictured.

For the first gen, the red wire with the yellow strip in pin 9 is the high beam wire from the switch. That wire gets switched to ground when the high beams are flashed, so you would use pin 9 as your switched ground wire.

You would want to use a relay that you switch the coil of with that wire, and then use the normally open relay contacts to trigger your garage door opener's switch.
