I'm converting a 2008 Nightster to a Custom rear fender, brake light and turn signals. Can anyone tell me how the Custom's wiring harness is set up, and even better, what the part numbers are for the wiring harness?

I see that the factory bobtail rear fender has a strip of glue-on conduit on the inside; does the Custom share this, or does it make do with clips?

Any assistance is gratefully appreciated.

Thanks for the link -- it explained a lot!

So, it seems that the rear wiring harness is a single assembly that plugs into a circuit board in the tail-light, and the turn signals each have leads that enter the tail light and plug into sockets there. However, I'm not sure if the wiring harness is kept in a conduit attached to the underside of the rear fender or instead is held in by clips.

Can anyone enlighten me?

 

It seems the rear wiring harness is flat-sheathed with one side having adhesive; that allows it to be glued to the center of the left underside of the fender.

The engine end of the harness attaches to the fender with a round plug from which the wires protrude and terminate in a fitting that plugs into the main wiring harness. The other end enters the tail-light and plugs into a terminal block inside; the turn signal leads (which should be furnished with the turn signal units) enter the tail-light as well (they are held in place by glue-on clips) and plug into the terminal block.
