Hey everybody, I have an 05 f350 and I don't have marker lights on any trailer I plug into, I have power breaks , turn signals, four way flashers, reverse lights tho, I need to figure out this asap so I can haul a trailer at night an not worry about getting rear ended, is there a fuse somewhere that controls the marker ( clearance) lights? I've already replaced the 7 pin plug and am stumped. If there is a fuse does anyone know which one I don't have the diagram for the fusebox,
If you want you can email me @
