Super abbreviated install here with a few pics ( all attached )
I went with the OPT7 Triple light bar. You need to mount it just above the bumper or the tailgate will hit it when it opens. You also need to use the metal brackets and spacers ( I used stainless washers form home depot ) to attach it in order to clear the wiring for the tailgate and camera. If you don't have that wiring harness then you wouldn't need to do that.
I used the Curt 5 way harness to attach the light to the towing harness. Curt part # 56584.
I then used a hopkins 5 way connector kit to make my own harness to the light bar. IMG_154
I used both ends of the connector kit and connected them together. IMG_150
I used a male bullet connector and connected it to the white wire from the LED bar for the reverse lights. IMG_156
I can use then that bullet connector to connect to the harness I made using the trailer connector kit. You can get the idea from IMG_147
With all of that said I took one end of the connector, attached it to the light bar connector, attached the bullet connector and taped it all together. IMG_158
Then you simply have to use the other end of the harness to plug into the curt connector. All Done. I know you can do this A LOT simpler but I wanted a way to simply disconnect form the curt harness and take the light bar off if needed. This way nothing is spliced into the truck or connector and I can easily remove it if needed.
No issue with blis, backup sensors or anything else. I will take a video later on and post to youtube. I will add the link to this thread when I get around to that later. Feel free to ask any questions. I know this may not be that clear. Hopefully the attached pics help.
