Hook up Yamaha LCD Meter

[Jay.gleason@mindspring.co]

Purchased a Boston whaler with a 2003 4 stroke T60C with under 250 hours. Boat has 2 Yamaha LCD meters. The RPM unit is all hooked up, the other unit with Speed/ battery / Gas gauge is not hooked up. I have determined that the separate wire set with a black and Blue provide gauge lamp power

The 2nd wiring harness has 7 wires, 2 black, one gray, yellow, red, white , and one white with blue stripe.

Would appreciate a wiring diagram for this gauge.
Thanks

Black= ground
Red = 12 volt power
Yellow= 12 volts key on power
Blue= backlight in gauge
white/ blue= fuel tank sender lead
Gray= overheat warning light
white not used

could also be of some use to you if they are command link gauges, although the last comment from boats.net is perfect
