They may share some grounds and powers, but as for data and depending on one another, i don't think they do.
If it does require any signals from the pcm, or at least a vss input, that isn't included with our harness, because our harness is a stand alone, emissions free, engine and trans harness, as most harnesses are out there.

Talked to Erica again today and she straightened things out. I now have a clear understanding of what my options are and what needs to be done! A+ on customer friendliness/service.
