I decided to spice my wires for a hitch wiring...anyway, now my tailights and directional light do not work. I checked the fuses and they all good, reassesed the wires, it's good. Headlights work, breaklights work...no clue what else could be wrong. Please help.

 

I can't even figure out which fuse is for the taillight, even after looking at the manual...any ideas? Thx
