I did this so I had light to cook on my tailgate when camping. The wiring goes from behind the cargo panel, up the driver’s side d-pillar, through the rubber boot into the hatch, through the inside of the hatch, and out of the hole for the lock. It was a huge time consuming pain running the wiring, but I wanted a clean install.
Inside of these things are stick-on LED strip lights that came on a roll. I soldered some power/ground leads to each, and soldered those to the wires coming through the hatch.

Behind the cargo panel I have a fuse box for positive and a bus bar for grounds (the four screw heads are bolts that are securing that stuff on the back side). I installed the USB charger/voltmeter, and the small toggle switch is for the hatch lighting. The switch ended up take a few hits so I’ve now changed that out for a flush mount push button. All of that is fed by a large 12VDC power cable that’s tapped off the supply for the stock fuse panel. And it has its own fuse up front, just in case the wire run to the back gets compromised.
I’ve thought about offering the lights as a somewhat pre-wired kit, but haven’t because it’s very labor intensive and I don’t think people would go for it. It’s all Amazon stuff anyway.
