Default Yamaha Wiring Harness?

The detail drawings of the Yamaha wiring harness are not very descriptive. They tell you colors but not function, which is quite annoying. Does anyone know what the wire colors are? Is there somewhere on the web that has typical wiring harness drawings? Any help is greatly appreciated.

I do not have the wiring diagram at the house, but I think the Yamaha factory service manual gives the colors. Unfortunately my manuals are seventy miles from here. Perhaps someone with the manuals can offer more assistance.

And by the way, WELCOME ABOARD!

what color are you interested in and what are you trying to do? I might be able to lead you in the right direction.

I am trying to figure out which wires to bring to the Tach and Trim. I'm 99% sure the green is the tach, but the trim is a different story...it should be pink, but there are no pink wires in the harness ?!?

Go to the sending unit for the trim. The black doohickey that moves up and down with the motor.

What color wire is coming out of it ??

That should answer your question.
