Suzuki Samurai EFI Wiring Diagram - EGR/EVAP Solenoids, Clutch & Shift Switch

Wiring diagram showing EGR/EVAP solenoid valves, ignition and starter circuits with clutch pedal position and shift switches.

AI caption · Photo 26 of 86

This scanned wiring diagram page (uploaded as EFI4.gif, part of a multi-page EFI wiring set) shows portions of an engine control / starting circuit. On the left, a Bl/B (blue/black) feed supplies both the EGR Solenoid Vacuum Valve (connector C05) and the EVAP Solenoid Purge Valve (connector C06); their outputs run on Lg/W and Lg/Y wires through connector C10/E54 (pins 4 and 9) to the Engine Control Module at pins E34-15 and E33-25. ECM outputs on Y/B and B/Y wires lead to the A/C Amplifier. Two starter-circuit variants are shown side by side: variant [1] uses a Clutch Pedal Position Switch (connector E62, OFF/ON contacts) between the Ignition Switch (ST) terminal E42-6 (B/R wire) and the Starter (connector C04) on B/Y wire, passing through connector E54/C10 pin 7. Variant [2] (apparently for automatic transmission) routes the B/R feed through a Shift Switch via connectors C18/C07 before continuing on B/Y through E54/C10 pin 7 to the Starter C04. Wire color codes, connector numbers, and pin numbers are labeled throughout.

Frequently asked questions

What wire color feeds the EGR solenoid vacuum valve and EVAP solenoid purge valve?
Both solenoids are fed by Bl/B (blue/black) wires at pin 1 of connectors C05 (EGR) and C06 (EVAP).
Which ECM pins do the EGR and EVAP solenoid control wires connect to?
The EGR solenoid's Lg/W wire goes to Engine Control Module pin E34-15, and the EVAP purge solenoid's Lg/Y wire goes to pin E33-25, both passing through connector C10/E54 (pins 4 and 9).
How does the clutch pedal position switch connect in the starter circuit?
A B/R wire from Ignition Switch (ST) terminal E42-6 feeds the clutch pedal position switch at connector E62 pin 1; the switch output (pin 2) continues on B/Y wire through connector E54/C10 pin 7 to the Starter at connector C04.
What connectors are used for the shift switch?
The shift switch uses connectors C18 and C07, with B/R feed wiring and output continuing on B/Y through E54/C10 pin 7 to Starter connector C04.
What wires run from the ECM to the A/C amplifier?
Y/B and B/Y wires run from the Engine Control Module area down to the A/C Amplifier.
