  • New 90 two stroke - wiring?

    Brand new Yamaha 90 two stroke (carbs, oil injected), and trying to find the part numbers for plug/play connection to the following gages:

    6Y7-83540-80-00 Tach
    6Y7-83670-40-00 Trim
    6K1-8258A-40-00 Main Harness (26FT)
    704-82570-08-00 Key switch panel

    connecting to a Morse MT-3 binnacle with neutral safety switch.

    What's the missing harness part numbers? what colors are the two connection wires to the binnacle safety switch?

    Any help is appreciated.

    Anyone?

    Does anyone know the difference between these two gauge harnesses, other than price?
    68F-82553-70-00 Trim/Oil Harness
    68F-82553-80-00 Trim/Oil Harness

    Is this gauge harness a universal harness for analog/digital gauges?

      The 6Y5-83553-N0-00 will work on either style gauge.
      The 68F-82553-70-00 is 22ft long and -80 is 26ft long, but the -80 is no longer available. 68F-82553-70-00 and 68F-82553-90-00(31ft) are still available. the 68F harness will work on 1994-2004 engines, if your motor is 2005 or newer use 6Y5-83653-00-00(16ft) or 6Y5-83653-10-00(20ft) Trim/Oil harness.

        Thanks for the help! One more question before I can figure out what I need...
        Can I get a 2005-newer harness just over 20', the existing installed is a hair over 21' to the gauge and a bit tight? May be able to get away with 20' if the gauge harness gives me a foot or so in slack under the console (1996 22' Glacier Bay center console), but I wouldn't want to guess on that.
        Is the 6Y5-83653-20-00 23' Harness I found in the boats.net site parts search a valid and obtainable part number or is there some other p/n combination I need to get 21' from the ob connection to the gauge?
        Really appreciate the help in trying to get this boat back up and running, wish I knew about this site sooner, but I'll be a customer shortly to support my two new 90 two strokes.

          Yes 6Y5-83653-20-00 23ft or 6Y5-83653-30-00 26ft are available for the 2005 and newer.
