So... I tried grounding to G105, G106 and direct to the battery. No change. Still randomly shows speed on the speedometer when standing still. As previously noted G105 and G106 is where the ECU grounds. They are two grounding bolts adjacent to the top bolts (right and left) that hold the bellhousing to the engine. The next step will be to change the positive connection. I'm open to suggestions...
