Huh, I wouldn't have thought that.... I went with:
- black with red stipe to black with red stripe,
- green with red stripe to green with red stripe,
- yellow with red stripe to yellow with yellow with red stripe, and then there are the two black wires.
Anyhow, before everything worked except the starter button, and now I have the starter button working, but have lost the headlight, lost the left turn signals and cannot be sure about the ignition (red on-off switch).
A marginally discouraging repair / upgrade.
