No power to blue pin 59

The motors a 2002 3800sc from a regal that's installed in a 86 fiero. I initially had power to pin 59 which goes to the obdII pin 2. Without that data pin I can't hook up to hptuners to delete the vats. Anyone know what feeds that pin? I'm not sure what changed. I did try another PCM from a grand prix with a compatable service number but it too did the same thing.
 


Over on hpt I was told that there should be no power on that pin as its only a data used for transferring information. I pulled all my wires from the harness to tidy them up and when I hooked them back up, I was able to connect to hpt again.
