WIRING DIAGRAM Z — Engine Control System (Sheet B-1c)
Z-32wiring diagramClutch and neutral switches are M/T-only. Air-bag control unit and cruise control unit branches are Federal & California only.
ENGINE CONTROL SYSTEM — Sheet B-1c
Final sheet of the engine-control-system schematic. Continues the ECU pin map and cross-references most other system sections: main relay (B-1a), cooling-fan/A/C/heater/thermoswitch (G), horn relay (F-1), instrument clusters (C), stoplight switch (L-2), circuit opening relay (B-2), igniter (B-1a), air-bag control unit (S — Federal & California only), and cruise control unit (Q — Federal & California). M/T-only branches add clutch and neutral switches.
