Where does the ECU ground terminate? The engine or the chassis? I plan on running a wideband gauge and want to use the same voltage reference (ground) as the ecu without tapping into the harness.

Sorry, used to posting on year/model specific forums... It's a 2003 MazdaSpeed Protege.

http://protege5.ugly.net/#ac This link is for a 2002. But the wiring diagrams would be similar, but I would definitely try to get a diagram that is specific to your car. But this might point you in the right direction.
