Yes, this site has a write on how to do it. It's as simple as pinning the PCM providing the PCM can control the IAC, not all can. My 03 PCM I tried using wouldn't so I picked up a 02 PCM...harness I used is a 05 6.0/80e harness. A few pins needed to be swapped or added but it was pretty easy. So 05 harness with 02 PCM and it's dbc
