Where does the power window circuit get its power?

From the ignition switch IG2 terminal via connector E42 pin 7 on a Y/B wire, through a circuit breaker, then on a Bl/W wire to the power window main switch.

What wire colors run to the front left power window motor?

A Y (yellow) wire from pin 4 and an R (red) wire from pin 3 of the power window main switch, passing through connector J17 pins 2 and 1 to the motor.

How is the power window main switch grounded?

Through a B (black) wire from pin 9 of the switch, through connector J30/E36 pin 3, splitting to two chassis ground points labeled 10 and 9.

Does the diagram show a window lock switch?

Yes, a Window Lock Switch with ON and OFF positions is shown inside the Power Window Main Switch assembly.

Which connectors are involved in the power window circuit?

Connectors labeled E42, E36/J30, J27/J28, J18, E35/J29, and J17 are shown in the circuit.

This document is a scanned power window wiring diagram, uploaded to a 1986 Suzuki Samurai gallery as part of a larger factory wiring diagram set. It shows the circuit from the ignition switch (IG2 terminal, connector E42, pin 7) through a Y/B wire to a circuit breaker, then via Bl/W wiring through connectors E36/J30 (pin 1) and J27/J28 (pin 1) into the Power Window Main Switch at connector J18 (pin 10). A parallel Br/B feed runs through connector E35/J29 (pin 2) to the switch. The main switch internals are drawn, including UP/DOWN contacts, internal relays, an illumination LED with resistor, a Window Lock Switch (ON/OFF), and secondary UP/DOWN switch positions. Outputs include Y and R wires through connector J17 to the front left power window motor, a B (black) ground path through J30/E36 (pin 3) to two chassis grounds (points 10 and 9), and G/B and R/B wires routed to the right toward other circuits/switches (continuation arrows). Wire colors documented include Y/B, Bl/W, Br/B, Y, R, B, G/B, and R/B. A reader can use this diagram to trace power, ground, and control wiring for the power window system and identify connector pin assignments.
