Is it just me but I'm having a problem with the wiring for this light.
My tour pak only have 3 wires in the harness . The new LED have 5. None of the connectors match, this is not plug and play. If I have to engineer it work I will, but I want plug and play ( 
Trey, I picked up the installaton instructions at the dealer today. They aren't very good based on a quick read.
That said, it appears you disconnect the Ultra light bar connector from the tour pak harness (the three-wire connector that goes into the tour pak) and you don't use that tour pak harness for the LED light bar. Instead the LED light bar uses a connector for the LED wires that is then connected to a long harness that runs to the rear lighting connector (under the seat/atop the rear fender). This is an oversimplification since you have to assemble wires in a couple of connectors, but the point is the LED lights get their run/brake/turn signal from the rear lighting connector under the seat, and not the regular tour pak harness currently used in your tour pak.
As for removing the OEM Ultra light bar, apart from the metal clips and nuts that must be removed, the only thing holding the light bar in place is the RTV silicone and it's a PITA to remove around the light housings to free the light bar from the tour pak. I've done it twice on two different Ultra tour paks to have the light bar painted to match the tour pak and it doesn't get easier with experience.
