NOTE: All BLACK wires with a ground symbol are interconnected within the EFI system harness. NOTE 1: As a mid year (96-1/2) model change, the MPI (Multi Port Injection) models have the lanyard stop connector removed from the wiring harness. The dual engine capability is relocated by routing the YEL wire to the Data Link Connector (DLC). 1 2 3 4 5 6 7 8 9 1011-
