    98 1100 STX ECU Help

    I have a 99 STX 1100 with a bad CDI. I purcashed a 98 parts ski today with a known good ECU. It has an extra harness coming out of the front that my 99 does not have. Any ideas what this might be for? I went through all the parts diagrams and cannot seem to find this referenced. Thanks!

    The 99 STX has a different CDI and staror. I'm pretty sure it's not compatible with any other 1100. Some of the 900s have the same stator so maybe the CDI would work.

      Boy I hope I didn't buy this ski for nothing, but according to the parts diagrams, the part number on the CDI is the same for the 98 and 99. I have referenced boat load of pics and listings for ECU's, and cannot find a single pic that even shows the extra two joints going into the front of the ECU box that I have circle here. It was dark when I got home last night so I am going to follow the harness today to see what it goes to. That is my easiest way to get an answer. Just hoping this unit is going to work for me.

        I just double checked the Kawasaki parts diagrams and both the stator and CDI use the same part numbers for 98 and 99.

          If you have the '99, you will need the CDI part number 21119-3755. It is unique to this one year only. The '98 is a 21119-3746. Not sure what you are looking at but 2 completely different units.

            The 99 ZXi is the same as most others. Only the 99 STX is different.
