PLEASE HELP!!!! I just bought an '01 OX66 Saltwater Series 225hp. I am trying to install the digital tach and speedometer that came with the motor (hope it is the correct one I need). Anyway, I am VERY mechanically inclined, however, running into a snag with the wires on the speedometer. I am down to a white and red wire, not sure where they should go. I was told by one person that the white is for a kill switch and don't remeber where the red was supposed to go. THEN, I was told that the red was a constant for the batt. switch and white for fuel level. Can someone please lead me in the right direction. I don't mind doing leg work to find the answer if someone can tell me where to look. Just bought a downloadable manual off the internet last night to help me out, but that seems like a waste of $10 and 2 hours. I can't wait to get this thing started.:confused:

Re: Yamaha Speedometer Connection

red is battery, yellow from ignition switch, blue for backlight, black is ground,

white is usually to fuel gage.

Thanks for the help, I was able to hook up the wires according to the diagram, able to start and run the motor......:DAWESOME!!! However,:( Can't get a reading out of the tach for ANYTHING!!!!! and can not switch the mode in the speedo (it will give me an indicator light for fuel, but can't switch from batt reading to time). Did I do something wrong :confused:or do you think they could be bad?:confused: PLEASE I NEED MORE HELP!!! Im ready to go fishin but the boat aint!!! :(
