Harley Boom Audio Relay?

Anyone know why Harley requires the use of a relay kit (part # 69200397) for some installations and not others? 2012 and newer Dyna's along with 2011 and newer Softails do not need the kit. It is not like it is being used to control a higher power circuit? Also, both wiring diagrams have the red and the orange/white wires tied together, not sure the purpose of this either. Why didn't they just use one wire?

I don't see why I can't just connect the two power wires (red and the orange /white) to a swiched circuit and use the on off swithch provided with the unit to turn the amp on or off.
