Yamaha fuel management gauge
 
Ok I m sure this has been covered but Iím still confused , iím trying to hook up this Yamaha fuel management gauge set up . The main gauge has a coupler which goes to the harness simple enough, and then a yellow wire which Iím assuming goes to key on power, a red wire which goes on to continuous power a black wire which I assume is ground ,a blue wire which Iím not sure where it goes and a green wire which I think goes to speedo and a green and white wire which is not used in a single engine application ,at the other end of the harness a coupler going to fuel flow transmitter simple enough and extra Coupler which goes to a second engine which is not used simple enough, ... and two butt splice connectors ,one has a red and white wire and one has a double black wire neither one do I know where they go .. any help please ?

At the gauge and of the harness I have a red wire, yellow wire, black wire, green wire ,green and white wire ,and a blue wire ,Iím not sure which one is ďLĒ, at the rear of the harness near the transmitter I have also two extra wires ,a red and white and a double black wire, I havenít seen anything about those anywhere ..

Yamaha offers a water-separator filter with a clear bowl a la Racor
which has a water-detection switch.
Those wires connect to the water-detection switch, the gauge can display a warning.

Red yellow and black are connect to the regular gauge harness-
always on power, ignition, and ground.

Yamaha uses "L" to symbolize blue wire - it is the gauge backlight,
you can connect it to yellow for always on, or your running light switch.

The green and green/white white connect to tachs -
the gauge has an rpm sync function for twin motors
