Been going through my airbag system checking things before installing a new diagnostic monitor. Went to veryuseful.com for the diagram. Anyway, the backup battery harness contains a ground wire though the diagram just shows a ground symbol (which I thought was a case ground) but doesn't show where this ground wire goes to... anyone know where the black wire in the backup power supply terminates so that I can check its connection? I checked it against battery ground and was getting a little resistance where their should be none and dont want to try finding it under the dash n messing with the harness if it comes out somewhere and I came ohm it out that way.
