I received one of these light bars for under my tailgate, above the rear bumper. It fits in there nice, should aid visibility and give me a bit extra light when working back there in the dark. It is supposed to connect to the tail light circuit, and I guess also ground, and has 2 short leads of wire for that purpose. Is there a simple way to break into the tail light circuit, maybe via the trailer wiring harness, rather than cutting into a cable to make the splice? I could splice in a flat-4 connector and run it out to the trailer hitch, but that isn't so clean. I don't know much about the wiring harness on this truck, but will crawl under there this weekend...just looking for any tips. Thanks in advance.
