Does the ap1 and ap2 use the same door harness?

 

It depends. I have a 2001 model that came without tweeters so when I put an ap2 door on the main plug that attaches inside the car had 2 extra pins on it (passenger side). I simply removed my ap1 harness and swapped it in the ap2 door. Everything plugged in no problem.

I'd almost bet on the 2002 (when they added tweeters) and on would be the same.
