Behind the license plate you will find where the taillight and turn signals come together, you can tap into the needed circuits in there. The connections are bullet style single connectors. I do sell some special multi tap bullet adapters but if you are replacing the taillight all together you may not need those unless you want to retain the OEM turns. As far as the light bar under the trunk I sell those with a plug and play harness that taps in under the seat, with enough information about your light bar I am sure I can make a plug and play set up for that also. You check out this thread if you like.
If you do not have this already here is the color codes for the rear lighting
Tail = Blue
Right turn = Green
Left Turn = Brown
Brake = Yellow
Ground = Black
Happy to help if I can.
Glad you like it, twisting the rod back and forth usually finds its way through the tab. I have mine up on one right now too. Voltage running a little low, thinking stator/regulator change is due after 80,000 miles
