Nissan Warning Lamps Wiring Diagram (With Tachometer) & Seat Belt Timer EL-50

This scanned service manual page (EL-50) from the Electrical section covers the Warning System, specifically the continuation of the Warning Lamps/Wiring Diagram for models WITH TACHOMETER. The main wiring diagram traces circuits from the fuse block and ignition switch (ON or START) through the main harness and instrument harness connectors (54M, 11, 61) to the combination meter, which houses the CHARGE, BRAKE, OIL, and BELT warning lamps. Wire color codes shown include Y/B, W/R, B, LG/R, LG, Y/PU, Y, G/Y, and G/L. Components in the circuit include the auto-choke relay, alternator (connector 7M), oil pressure switch, body ground (13M), parking brake switch (55M/75M), brake (fluid) level switch (21M), a diode (18M), and a seat belt timer (57M). A second illustrated section, 'Seat Belt Warning Timer,' shows the timer unit bench-test setup with a battery and lamp, noting the warning lamp goes out 'After about 6 seconds.' Illustration reference numbers SEL518I and SEL419 appear on the page. This document is useful for diagnosing warning lamp circuits (charge, oil, brake, seat belt) and testing the seat belt warning timer.
