I am adding a tilt/trim gauge to a 2004 Yamaha 150 Fourstroke. It does have a sending unit and seems to be wired to a pink & black wire set that goes into a wireing harness. I cant seem to figure out where it goes from there so I need to know if anyone knows if there is a wire for it that runs in the harness to the console or if I will have to run new wire to the engine and where do I hook it up?????
