Their are 4 wires just under the driverside dash ,closer to above emergency brake, they may have white tape from factory saying aux , otherwise its a yellow ,green/brown, violet/green,and brown wires ,they have blunt cuts with a black end on them. they are live and ready for you ,looking at switches starting w/#1 they go to right in order ,the yellow(aux#1) and green/brown (aux #2)are the ones youll want ,they are hooked to a 30amp fuse ,run all your wires accordinglly get your power wire from lights inside truck thru firewall , and hook to one or both wires depending on how many lights you want/have ,this should put you in the right direction ,FYI the other remaining switches 3,&4 are a 10 amp(3) ,and 15amp(4)
