Greenlee - Thanks for that thought. I just put a new battery cable on it this week, that has the provision for the alternator wire like you said. Will check that out.

Here's my current work effort - mapping of the bulkhead connector. My ECM doesn't have any power. I've never used a Digital multi-meter before, so it's been a learning experience.

I figured out tonight that B1 - the orange wire on the bulkhead, row 1 at bottom, doesn't have any power, so the computer doesn't have power. Will check that one out this weekend.
