I posted about the PUTCO light bar in a few other threads, but here is the info again:
I installed the Putco Switchblade 60" light bar. Make sure you get the 92009-60 if you have the BLISS pro-trailer option.
I don't like tapping into the factory harness if I can help it, so I also got a plug-and-play harness.
CURT 7-pin plug-and-play T-Connector (P/N: 55384):

It plugs in-between the 7-pin connection under your truck (behind the bumper, next to the spare tire).
The attached 4-pin connector on the CURT harness plugs right in t the LED bar, then you tap in the reverse light wire to the center wire on the 7-pin portion of the same harness. Since I have the BLISS pro trailer option, I did have to do a power connection under the dash so that it wouldn't detect anything and still provide a 12V source (their included instructions show you how to do this).
Also note that if you have the remote tailgate opener, you will need to use a spacer (~0.400" thick) for the light to clear the black bracket and bolt near the right side of the tailgate where the light goes. I used some dense foam I had around. I also contacted Putco with pictures and said their R&D department would look into it; but as of a couple days ago, they decided not to pursue it anytime soon.
I did find some pretty durable rubber products on Amazon though if needed:

I also found this tape to be excellent for this type of thing (and for odds-and-ends around the house):

Just don't forget to use adhesion promoter on every surface you plan to stick stuff to!
