I have a few manuals with wiring diagrams, I have found that they use the KTM harness and part number. If you pm me your email address, I can send you what I have. The color and pin out is identical to my 14 FE350.
I am also guessing that you might have had one of the pins come out on the plug? I am waiting for some info on the new speedo from Husa and will send this as well when I receive if you like.
