Review on Top-quality Nilight 10014W LED Light Bar Wiring Harness Kit: Waterproof Switch, Heavy Duty, 14AWG, 12V, 5-Pin Rocker, Power Relay, Blade Fuse - 1 Lead, 2 Years Warranty by Devin Girard

Overall, everything has worked great so far. I use it to power the lightbar behind the 4Runner grille. The switch can be connected in two ways. One draws power constantly, even when the car is off (but the switch is on), or you can wire it to only light up when the lightbar is on. The downsides of this are that the ends are a bit unwieldy so getting through the firewall was a bit of a hassle. Also, the derailleur doesn't fit my car (too big) and looks a bit cheap if you care. An OEM style switch will work just fine, but it's still something to buy. Overall, this is a solid product at a decent price that does the job I've been asking for so far.
