Suzuki Samurai 8v EFI Swap ECM Connector C2 Pinout - Wire Colors & Circuits

This document is page 2 of 4 from an '8v EFI Swap Info' guide printed from yankeetoys.org (dated 8/22/08). It documents the Engine Control Module (ECM) connector C2, a yellow 24-pin connector shown in a diagram with pins numbered 1-12 on the top row and 13-24 on the bottom row. A table lists pins 1 through 22 with their wire colors, circuit functions, and swap installation notes. Circuits covered include the Tach Signal (Brown, pin 1), A/C On Signal, Diagnostic Request, California-only Ground, Power Steering Idle Up, Test Switch Signal, Evaporative Canister Purge Solenoid, Duty Check Output, TCC Relay (automatic transmission), Igniter Driver, CMP Sensor, Idle Switch, VSS input, EGR Temp Sensor (California), IAT Input, Temp Sensor, O2 Sensor, Serial Data Output, Throttle Position input, and MAP Input. Pins 5 and 10 are empty. The author's notes indicate splicing the tach signal to the instrument cluster tach wire, leaving the OE diagnostic connector intact but relocating it under the dash, routing the power steering idle-up circuit to the power steering box, and connecting the VSS input to a new VSS output in the dash harness. This is useful for anyone wiring an 8-valve EFI engine swap into a Suzuki Samurai.
