on the 07 aveo hatchback manual tranny which wire would the tach wire be at the instument panel, some of the wire schematic sites say pin 3 but the funny thing is there not numbered so i checked all 3rd pins from outside in and came up with 12 to 14 volts with vehicle running any advice would be greatly appreciated, trying not to run to the ecm on the shock tower. thanks in advance
