I couldn't find any thing that would help me fix this. So that I have is my fender chopped and I got new lights and some converter pack that pluges right in but only works with the original break light and turn signals witch are gone . I got my new lights spliced in directly to the harness but only work for drive lights and the left turn signal only. On a diagram I've seen the lights are supposed to plug in with this converter box but I don't have the connectors



The lights are mounted to the left over brackes from my saddle bags

 

Check your wiring, on the schematics the tail light should be as follows:
Black is the Ground
Orange/White is the Running light
Red/Yellow is the Brake light
Brown is the Right Turn Signal
Violet is the Left Turn Signal

The left and right turn signals both need to be connected to the ground, are the lights incandescent or LED, if they are LED then you will need a load balancer in order for the turn signals to flash properly.
