Electronic Control Module (ECM): Sidekick

ECM is located under left side of dash. ECM distributes power to sensors (except oxygen sensor) and switches and controls ground circuits of solenoids. On TBI models, ECM power is sent from the EFI main relay to ECM terminals B1 and B7. On MPI models, ECM power is sent from the EFI main relay to ECM terminals A12 and A13. ECM back-up power is received from fuse box 15-amp fuse No. 3 at ECM terminal B9 on TBI models or ECM terminal A1 on MPI models.
