Hook up your grounds and try the other conductors, Its not magic and it wont bite you, just use caution not to short it or you’ll cook a fuse. If your bike only has two wires coming from the harness, it just wont have running light functionality.

 

Not sure which wire is which but perhaps it's time to get a multi-meter.

Harbor Freight sells one for under $6 that would do what most people need.

Little help from you as well:

1. What bike (year/model)?
2. What light kit (part#)?
3. Pics (best to have visuals)?

If you're wanting assistance...throw us a bone, man.
