WD PCB Terminal Connections

You probably just had a potential between your grounds of the terminal board and the HDD PCB and the third wire corrected it. If they were both plugged into the same USB header of the motherboard you probably wouldn't need that third wire.

I know the terminal connections, but it seems like it operates at a different baud rate or something that prevents PC-3000 from working with it in boot ROM code mode. At least my slightly out-of-date version of PC-3000 doesn't, maybe they've fixed it since then.

And this one added by Wayne on Ace forum for the 800041 & 800022 boards:

On some passport boards this method doesn't work for me. I have a 800041-000 REV P1 (3TB) in front of me right now. What does work is adding a third connection from the next available pin on the HDD.

Tested on a 800069 and doesn't work...

Are you able to get it into boot ROM code mode? I've found that these often seem like they go into boot ROM mode (platters don't spin as expected) but then PC-3000 still can't communicate as if it's the wrong baud rate or something.
