I am a bit confused...I have two sets of turn signals that both require a ground wire. The wire harness has only one ground coming from under the seat. I am not using the electrical board that once existed in the stock tail light assembly. Do I just splice twice into the ground wire, once for each signal and then ground the wire to the frame since the side mount plate is self-grounding and only requires two wires to run the stop light and running light?

Also, what is the Orange and white wire. Where would that connect to?

 

It's a 2007 street bob

 

Connect all the grounds together.
The O/W wire is accessory power and is not used at the taillight, just cap it so it cannot short against anything.
At the bottom of the linked page you will find a wiring diagram, it should help you.

Thanks for the help! If I were to use the circuit board, I am missing the connectors that plug for both turn signals that plug into the board. I threw out my stock signals that had the connectors attached to plug into the board when I went with the panacea tail light. Do you know where I could get these connectors? I like the idea of using the board and having quick disconnect. Keeps a clean install. Thanks....

 

I don't believe they are standard Deutsch connectors, got rid of mine a long time ago, so not sure if you can buy them anywhere by themselves.
If you have the board loose you could take it to Radio Shack and see what they have, other than that I would take the board out and solder and wrap the wires.
Slide a large shrink tube over all the wires first, then individual tubes, solder and shrink the individual, then shrink the whole assembly after you verify everything works.

 

Appreciate the help. Will check on radio shack. Thanks again

 

Anytime, hope it works out.
