Wire color code (harness symbol) •
•
Two-color wires are indicated by a two-letter symbol.The first indicates the base color of the wire, the second the color of the stripe. For example: W/R is a white wire with a red strip BR/Y is a brown wire with a yellow strip
•
Like connectors are linked by dashed lines between the connector symbols. Connector diagrams show connectors on the harness side. The terminal indicates the view from the harness side. (Example)
