Question On Wires For Temp Gauge

[yamaha06]

I am in the middle of wiring mine up and am going to use the blue/white wire, as well as the red/white. Anyway I see the blue white wire coming out of the fuse box but my gauge wires aren't long enough to reach there. There is a bundle of wires near the oil tank, (going to the starter relay and main fuse) and they looked like blue white and red white, so I cut all the tape apart and there blue white and red white but they have 2 green marks every so often on them. Could I still use these wires or are they not the correct wires? I looked in the manual and it says nothing about red and white wires with green markings
Thanks
