Suzuki Samurai Ignition Circuit Diagram - ECM, Igniter & Coil Wiring

This document is a scanned ignition circuit schematic showing the wiring between the ECM (Electronic Control Module) and the ignition system components. The legend identifies five components: (1) ECM, (2) ECM coupler, (3) noise suppressor, (4) ignition coil, and (5) igniter (power unit). The schematic shows ECM coupler terminal A8 connecting via a brown (Br) wire toward the noise suppressor, with a black/white (B/W) wire running to the ignition coil and a brown/white (Br/W) wire to the igniter. The igniter block has terminals labeled IG1, COIL, and GND, with a black (B) wire from GND to chassis ground. ECM terminal A4 connects to the igniter via an orange (Or) wire. The noise suppressor is grounded via a black (B) wire. A separate illustration on the right shows the physical ECM coupler (connector) with the locations of pins A4 and A8 identified. A reader can learn the wire colors, ECM pin assignments, and component interconnections for diagnosing the ignition/igniter circuit. The document itself is undated and does not state a vehicle model; the uploader filed it under a 1986 Suzuki Samurai.
