Yamaha digital tachometer 6Y5-8350T-81-00

[Tournament 223]

Hello,
Just got onboard and bought a 1997 GW Tournament 223 with a 1997 200HP saltwater series II when I recieved the boat the tachometer was defective so I bought the above listed used tach from another boater who said it was off a 2000 model motor and that it would work.

I have hooked it up color for color except there is an additional lead on this one compared to the old tach of a blue wire.

Right now with out that blue wire connected the tach does not work it just shows the letter E ??

Does anyone have a wiring diagram or advice to help me out... Thanks Steve.

are you not using the harness? as far as i know, blue if the light on tack and green is the tack signal.

Hello JB,
Thanks for your reply,
I'm not using a separate harness.... this is what I have.

Large connector with PINK, ORANGE, GREY, BLACK & WHITE. (plugged into matching conn.)

Small connector with GREEN & RED, GREEN & WHITE. (plugged onto matching conn.)

Same bunch of wires as above but individual BLACK, YELLOW, GREEN,.....BLUE? that I did not have on the old Tach. (all conn color for color except the Blue not sure where it should go?

And another pair of wires BLACK, BLUE. (conn. color for color)

ANY HELP WOULD BE APPRECIATED.... Steve.
