Handbook 652 Body Electrical Diagnosis Tracing Wires On very large wiring diagrams, it can sometimes be challenging to trace wiring from one component or connector to the next. Clicking on the wire, however, highlights the wire and the component or connector at each end, making it easier to trace the path. With the components at either end highlighted, it may also be helpful to simplify the diagram using the Compact Display button. Clicking on the Component Detail button brings up the connectors with the corresponding pin highlighted. Technical Training 107
