I have a 2002 avy 2500 and just recently picked up a 2005 escalade ext and was wondering if the wiring harnesses for the interior are the same I bought the caddy for the interior and want to make sure all the bells and whistles work when I change the interior out
 
my guess is NO since 2002 is way different electrically then other years.

Confirm this by checking PNs on some GM online parts store.
 
Completly different. You need a 2002 for 2002... 2006 for 2006... 2003-2005 for 2003-2005.
For the engine compartment only the 2004-2005 shared the same harnesses. otherwise year dependent.
 
So even the interior harness is different so I'm gonna have to make my own for the heated seats and sunroof o joy
