Suzuki A/T Shift Lock & Illumination Wiring Diagram - Shift Lock Relay/Solenoid

This scanned wiring diagram shows the automatic transmission shift lock and related circuits for a Suzuki vehicle. Power comes from three 15A fuses (positions 14, 20, and 13) in the fuse box. The diagram traces the stop light switch circuit through a diode (E83) to the shift lock relay (E64), which controls the shift lock solenoid (I06). It also shows the lighting switch (E40) with OFF/TAIL/HEAD positions feeding the dimmer & passing switch and the shift illumination lamp (I07), whose output continues to an illumination controller. Cruise-control-equipped vehicles route through the cruise main switch (E41) and actuator, while vehicles without cruise control use the A/T TCC relay via the fuse box. The shift switch (C17) shows gear positions P, R, N, D, 2, L and grounds through a B/G wire. Wire colors identified include Y/G, LG, G/W, Y/Bl, Bl/B, Bl/G, Bl/R, B/W, W/R, R/Y, R/G, B, and B/G. Connector/component codes include E38/G05, G24/I01, E54/C10, E55/C11, and E84 (diode). A legend distinguishes van type, canvastop type, CAMI vs. IWATA production plants, and vehicles with or without cruise control. A footnote (*1) shows an additional diode circuit (E84) for certain variants.
