Four my lights on the roof rack (4 PIAA 80 Pro XT 385,000 candlepower 120 watt bad boys) I brought the wires in through the roof. Stupid me though, I didn't pull back the headliner to see where the roof braces were first and just drilled... got two holes right, missed one... result? water leaks, and I've been to lazy to fix it lately. Possibly tomorrow I'll work on it. Basically since I had no grounding spots on the roof (I am using the stock roof rack which, of course, is not properly grounded) and I have not yet added an aftermarket light bar... purchased a Carr "deluxe" rotabar, which turned out to be a hunk of crap and I pitched it. So I had to bring the wires down through two holes (one hole for the ground wire, one hole for the power/switch wires, total of 6 wires through two holes. It looks extremely unprofessional for now and as anyone knows who has seen it, usually if people ask to see how I brought the wires through I say "for the love of god please don't look up there!" Its a mess. Zip ties, silicon, duct tape... its terrible. The problem was when I was installing it it was FREEZING and I was just trying to get it all done before the Truckhaven run in January, so I didn't spend as much time on it as I should have. One of these days though I'm going to devote the whole day to it, and I'm gonna combine wires so I have less, get improved grometts and seal up the spare hole a lot better, and pull the wire through to the interior so I don't have a bunch of ugly wires zip tied up there! Hmm... now I have a project for tomorrow! As for the sunroof, thats a good option, but where will the wire go once you bring it through the sunroof? Going to run it along the headliner or what? Either way it should work, though it might inhibit water leakage.
