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.
