Default What is this green wire?

I took the tail light lens off my 2008 Fat Bob. I see these green wires with loose electrical tape on the ends. What are they to? Tail light, brake light, & turn signals all work.


I don't see it in this diagram. https://app.box.com/shared/88yp0f4xno

Did you try testing them with a VOM or test light? I try that and see if any of the functions such as brake etc sends power to them. Some one may have added some sort of auxiliary lights at one time

This isn't really going to answer your question, but as a point of reference my '010 FB taillight doesn't have those two green wires coming out of that connector. Doesn't appear to be OEM wiring, as they look newer and of bigger gauge than the others. In any case, I would at least put a cap on the ends to prevent any shorts. Hope you get it figured out.

O-Town D I agree they do not look factory at all. I be willing to bet they was at one time used for marker lights after looking where the located in the harness. Dave Blank i just cap them and seal them and forget it.

Hi,

If the two green wires are tapped into the 3 way plug then looking at your photo, the left is your tail light feed, the right is ground and the middle stop light feed.

If they don't connect, where do they go?


Hope that helps.

If the wires tun into the connector to pin 1/2 and 4, to me it looks like the previous owner tried to connect an additional running light...

I capped them off before I reinstalled the lens. I'll check them next time I have it apart for voltage & continuity to ground.
