Ground Points




Ground point means the position where the negative harness among wiring harnesses is grounded. The diagram shows such ground points. In the system circuit diagram, there are many ground marks followed by black circles with numerical figures in them (10) which mean that the end of the harness with such black circle is grounded to some part of the vehicle.

To locate the ground point (installation position), refer to ground point diagrams.
