yea man, shorts can cause fuses to blow. i think youll be good to go after you get a switch. if not its in the wiring.

 

^^ maybe

 

ok, im having problems with my lights too, i thought it was the bulbs or fuse so i replaced everything, now my tail, reverse, and hazard lights work but when i push the break pedal nothing happens, wat else could it be, could it be the switch? or is there a censor that idk about

 

done anything to the radio lately? There is an illumination wire back there that if you are not using it needs to be insulated to keep from shorting out and blowing fuses.
