I'm running a 2 wire alternator off of a 2004 Chevy truck (140A). I had it checked and it checked out as "good". Any thoughts?

The generator codes may be because the 04 alternator has an internal regulator, and your engine/pcm would normally use a PCM controlled regulator. It doesn't see the voltage it would be trying to control. OR you have a short on one of the wires.
The p057c code came up as an SES for failed cruise control module. I'm guessing you might have something wired off the TCC/brake switch incorrectly (lol I know you and JorgenSC have gone back and forth on diagrams for this in the other thread).
can't find anything on the p2537
