I just got my ecu from locashracing. I ordered the custom ecu, ecu adapter, dizzy adapter, and engine subharness. I can hook everthing up right but i am not sure about the engine subharness. I am not sure if i need it or not. Can i just hook everthing up to the old wiring and not use the subharness. If i do need it when i unplugg the connectors from the old wiring what do i do with them do i just leave them hanging there or should i cap them off. If I can just plug everything into the old wiring that would be alot easier. Does anyone know what I should do.
Thanks
