Multifunction tach/speedo wiring diagram

Does anybody have the wiring diagram for Yamaha 2004 150 Hp for the speedometer and tachometer. I just replaced the dash and rewired the boat but now the tach gauge doesn't work.

Also, is there any way to test it or the wires leading to the gauge?

Thanks.

Thanks!

Thank you for the quick reply. This is a great forum!

I will print it out and try following it to see if I have something connected incorrectly.

Boats,
Is the schematic for a fuel management guage different than that schematic abovee? If not, can you post the fuel management diagram? Thanks.
