JCWhitney sells KC for a good price, I got my windshield lights and brackets, that don't interfere with the radio antenna, for $99 bucks about a year ago
My wiring is part of my OB relay/SW sys, so you'll have to "search" to get several wiring diagrams.
If you want the bumper type, I have "Navigators" and they sell for $60 bucks, complete with all wire/relay/sw. and connecters !!
