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 Paul Lee

It was a really easy install as most of the connections were done for you. I had two problems with the suspension. The first was the connector between the switch and the relay. I couldn't get it through my firewall so I had to cut it off and reconnect internally. Another issue I had was that despite checking the dimensions, this switch would not fit in the standard switch slots on my 2007 Tacoma. The hole size is 39 x 21mm while the switch size is listed as 37 x 21.3mm for the mounting size. I ended up filling in a lot of material on the sides of the mounting hole, as well as the top and bottom. I would say the derailleur is probably almost 40 x 22mm.
