headlamp swap, a little help please :)

evening all

i hope that someone can help me, im about to start a face lift from 2003 to 2011, i have all the parts and just double checking before i take the car apart that no stone is not unturned,

i am changing the headlamps to the 2009 onwards (but not going for the led one's)

so no xenon lights

will the plug from my car just plug in (they look the same) or will i need to change the pins about???

hope some one can help or put me onto a thread that covers this

cheers
have a good weekend
