I am looking for a wiring diagram showing how the wires are routed from the factory in the truck. Specifically in the front cab. In this diagram #'s 18 & 20 are the 3 cigarette lighter sockets. There should be a + and a - connected to those and I want to splice into them some where down the line. There is also a 20amp fuse in the fuse box for the cigarette lighters. I don't smoke and want to put them to better use. Or if I can simply (carefully) pry them out the front and disconnect the cables that way, that would be simpler. I just don't want to break any tabs, etc that are holding them in place.
