ok. i have a 2007 yamaha f150txr outboard. i bought a new 704 binnacle control. that works fine. i bought a yamaha multi function gauge, and the harness adapter. the problem i have is the harness that comes from the motor has 2 round plugs. one for the control and one for the key switch. the multi function gauge has square connectors. how do i connect my multi function gauge up? is there another harness that comes from the motor that i dont have? please help. the motor starts and runs fine id just like the gauge to work. i feel like i am missing something here.
