Suzuki Automatic Transmission Control Module Wiring Diagram - Shift Switch & TCM

This document is one page of a Suzuki automatic transmission wiring diagram (uploaded as "tranny2.gif") showing the circuits feeding the Transmission Control Module (A/T) at connector E43 (pins 15, 22, 21, 23). Power comes from fuse box positions 14 and 15A and 19 (15A), plus the ignition switch (ST) terminal via connector E42 pin 6 (B/R wire). The diagram covers the shift switch (connector C07), which routes to the starter (B/Y wire) and the back-up light (Br/R wire), and carries Bl/G, Y/G, and Y/Bl signal wires to the TCM. Two stop light switch variants are shown: one <WITH CRUISE CONTROL> (connector E41 with the cruise control unit, cruise control actuator, and E85 TCC cancel relay, grounded at points 10 and 9) and one <WITHOUT CRUISE CONTROL> (connectors C11/E55 and E41). Both variants send a G/W wire to the stop light and a Bl/G signal onward. Intermediate connectors E54/C10 (pins 11, 12) and pins 11, 13, 9 are identified. Wire colors throughout include G, Y, B/R, Y/G, Bl/G, G/W, Bl/R, B/Y, Br/R, Y/Bl, and B (ground). A reader can trace TCM inputs, stop light switch wiring differences by cruise control equipment, and shift switch outputs to the starter and back-up lights.
