Understanding how to read connector codes on the wiring diagram is essential for tracing circuits and verifying installations. For the ATF3 lead generator T3, the diagram shows its lead wires terminating at a specific connector. The code X5017A6B identifies the exact connector and harness variant used for that circuit in this configuration. The X prefix denotes a connector, the numeric portion pinpoints the particular unit, and the suffix A6B indicates the harness variant and position used here. Because the T3 circuit in the diagram routes to X5017A6B, that code is the correct match for this installation. The other codes refer to different connectors or harness variants and would not align with T3’s wiring and pinout in this setup. To verify on the actual schematic, locate the ATF3/T3 symbol, follow the wiring to the connector legend, and confirm that the connection shown is X5017A6B.
