[Armour]

hey i got a 2007 ford f-350 6.0 powerstroke diesel harley davidson edition crew cab. my taillights arent working but everything else is working i had my right bulb blow so turn signal did not work also i replaced the bulb now both signals are working but still my tail lights arent working? all signals my brake lights everything is working but the tail lights i dont have my manual so dont know what fuse to check can anyone help me out and tell me what fuse to check? and if i doesnt sound like a fuse because everything else is working ( assuming the tailight fuse is tied in with a few other lights) what wiring could be possiblky burnt out. any suggestions are greatly appreciated thanks
