    Tech Question for EFI Gurus

    What sensors are used to trim the fuel delivery?

    I'm sure of: barometric pressure sensor, intake air temp sensor.

    What about: engine temp sensor, etc.?

    What about engine temp? I saw what looks like a temp sensor on the front right of the engine. Anybody have a wiring diagram of the EFI boats they can post?

    In your harness you will see what looks like a blank connection plug. But it's not, it's a loop plug (loops all the wires together) one of the black and org plugs is probably corroded.
