I have a 99 with the tail lights the have the small white reverse spot more towards the top. I have a buddy who is selling me the 2001 tails w/bulb holders. my question is what modification do i need to do to the harness...if any?

I found a DIY here http://www.audiworld.com/tech/ext38.shtml

but thats for a 97 or 98 with the yellow signal. So i would think its different for a 99?

 

Edit: Nevermind, I don't know the order of lights on the sedan tails. Good luck!

 

the 99.5+ ones go from top to bottom, fog, turn, reverse, stop. just flip flop the turn and reverse wires. just be careful and think about the proces b4 you start cutting wires because the dumb things are hella short. i recommend splicing in extra wires so you have room to play with in the future.
