hope im in the right section, swapping 2017 motor with smart craft to a boat that had 2003 225 efi, my question is where does the smart craft gauge hook up, does it hook to the wiring harness, if so will it hook to the 2003 harness,, done bought the wiring harness for the motor,, hoping that I don't have to swap the harness to get the smart craft to hook up,, if it does hook to harness where would that hook up at
