cdi wiring issue 98 xpress 300

Hi, my first post here. Short story, visiting my 75 yr old mom. She uses(d) an xpress to do farm chores and check cattle. Just before leaving for home my girlfriends daughter jumped on the atv and ran it into a tree at high speed. I ordered a used frame off ebay and the parts to get it going again ie wheel, tire. strut, a arm, exhaust . I had some time as Rebekah is still in the hospital. Ive got all assembled but when getting to the end and connecting the wiring I noticed the wires on the cdi dont match the schematics I was able to find online. The schematics has a blue wire connecting the coil and the cdi. the cdi wires match the schematic except theres a black/yellow instead of blue. No spark with black/yellow connected to the coil. The numbers on the cdi unit match the ones in the book. (also managed to find the polaris atv service manual for that year). Anybody know where that black yellow wire is supposed to go? Everything else seems to work in the electrical matching the board diagram to wires color. Im stumped,,, Thanks…
