Do not hook your fuel pump directly to the ECU. Instead, wire the ECU's fuel pump trigger pin to control the ground side of an external fuel pump relay. This configuration ensures the ECU can safely cut fuel delivery if the engine stalls.
Disclaimer: Always verify pinouts with a factory service manual for your exact chassis and model year. Electrical modifications should be performed by qualified professionals. suzuki k6a engine ecu pinout better
