Hi,
I purchased an after market LED head light for my Road King FLHRC, 2014 ("standard" 3-pin connector). I also purchased a specific adapter harness (3-hole connector in one end and two separate connectors for high-beam and low beam in the other). Now plugging it in, it doesn't light up........ There is a 3rd connector on the bike for which I think is for like a "parking light", small bulb, but this connector I have no place to connect.

Anyone knows if this should work as plug and play (as advertised..) or is splicing required? Should I just leave one of the connectors from bike hanging and if so, which one?

Thanks for input (bought the led abroad so costly to return....)
