Both of those wires appear to be spares. There were times that the manufacturer would the same wire harness for various projects, and therefore would have a wire color not used. In your photos, both wires look production stripped and unsoldered. Does everything work on you pin?

I think someone fiddled with the adjustments. The schematic (on IPDB) shows what wires should be at the various adjustment plugs:
Winner 3-5 Ball Adj (resized).jpg
The 3-5 Ball Adjustment female socket should have:
- grey-orange on the 3 ball side opposite and empty socket on the 5 ball side
- black-yellow on the 3 ball side opposite black-green on the 5 ball side
- white-orange on the 3 ball side opposite orange-blue on the 5 ball side
- black-green on the 3 ball side opposite white-orange on the 5 ball side
The order of the wires in the male plug would show you the order the pairs should be in on the female side.

The Novelty adjustment should have yellow-red and grey wires soldered on the female side.
