I think I got the first bumper like this one back in 2008. The one in the pic is a duplicate of the original and was made this year by a friend's shop.
For the wiring, I tapped the wire for my high beams just behind the headlight and use that to trigger the relay, which is used to turn the LED bar on. High beams have a whole new meaning now.
I'll see if I can get some pics of the brackets.....kind of hard to see with the bumper mounted.
But these are the KC brackets I used.

Just image a 2"x4" piece of 1/8" flat stock welded perpendicular onto the front of each bracket about half way up. The flat stock protrudes outward from the bracket about 2".....drill one hole in each protrusion and the Rigid bar bolts right on.
