Default Fatboy Taillight

Folks I just picked up a 2004 Fatboy that runs but has no rear lights at all. I picked up a Tombstone taillight with built-in turn signals from J&P and now I'm trying to figure out the wiring. The light has 6 wires:
2- Run light wires
1- Taillight wire
1- Right turn signal
1- Left turn signal
1- Brake light

Coming out of the harness I have:
1- Black wire
1- Brown wire
1- Blue wire
1- Orange/Yellow wire
1- Orange/White wire
1- Purple wire

According to the wiring diagram in my book (I'm not too sure about this book) for a 2004 Fatboy:

Brown = right turn signal
Purple = left turn signal
Orange/White = run light for HDI only
Blue = Taillight
Orange/Yellow = Brake light
Black = ground

My problem is, I have tried just about every combination I can and can't get the right combo.
Has anyone else done this job that might can shed a little light on what I'm doing wrong?

Thanks for any help. It's all I have left to pass inspection.

OK guys for future reference, I found the culprit. Everything was right except the ground wire from the bike was not connected. The light unit I bought said it was grounded to the frame when you installed it but it definitely needed the ground wire from the harness. After I installed the ground wire from the harness to one of the bolts on the taillight unit, it worked perfectly.
