Here's a post from LS1Tech regarding P0507 and VSS.
"I had the same problem. I have a standalone harness with a 1999 5.3 pcm auto trans in a 1992 chevy pickup 5 speed manual. I did a smoke test and fixed my vacuum leaks intake manifold gaskets but I still got that code. Hooked up my vss to my pcm and haven't had the code since. I think since the pcm wasn't seeing speed that it was setting the code thinking car wasn't moving."
