I recently repowered my boat and went from an old Johnson, to a new Suzuki. Only issue I have come across was during the install, the dealer did not hook up the fuel gauge I already have in the boat. There is one wiring that was diconnected from the back of the gauge that is supposed to go to the "Ignition Terminal" on the ignition switch. The owners manual doesnt' go into detail about what color wires on the harness are what. Can anyone tell me what color wire(s) go to the ignition switch?
