The page presents the C280 (gray) connector for the Warning Chime Module, showing a connector face view with seven numbered pin cavities and their associated wire circuit numbers and colors. A table lists each pin's circuit and function: Pin 1 - 14 (BR) Parklamps On Input; Pin 2 - 159 (R/PK) Driver Door Open Input; Pin 3 - 85 (BR/LB) Seat Belt Buckled Input; Pin 4 - 158 (BK/PK) Key-In-Ignition Input; Pin 5 - 57 (BK) Ground; Pin 6 - 450 (DG/LG) Fasten Belts Output; Pin 7 - 640 (R/Y) Power (Hot In Start or Run). A Connector Reference List cross-references related connectors to their manual cells: C219 (cell 31-3), C229 (150-10), C250 (60-9), and C273 (71-2). A reader can use this page to identify the correct wires when diagnosing chime problems such as no key-in-ignition warning, seat belt chime faults, headlights-on warning, or verifying power and ground at the module.
