hello im sure this horse was beat to death but i am really beating myself up here. 1969 cougar doing a 351 efi conversion..using my stock short block 351 efi lower 302 upper from a 89 mustang along with ecu anf complete harness. just wondering a few things...mainly wiring up power to the ecu..according to the reading i have done it is suggest you use the relay towards the ecu if im not mistaken to power the ecu and fuel pump. well just curious but i would assume the green connector is for the body harness to the old mustang which will of course not be used. ford used this connector to power the ecu can i power the ecu by splicing the required power wires onto my solniod from this connector? i know its not this easy but really the way i see it the harness will plug into required sensors then i wire in the fuel pump and power the eec/ecu to achieve required power to harness and sensors. power up the ignition system and boom running efi..lol..or am i missing the big picture?
