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.
