hey so id like to run my phone charger, radar, or whatever else in my car but the guy that i bought it from diddnt have it wired right tryed one charger once and it blew the thing up so id like to know if there is a certain volt wire it needs to be or what i was told it diddnt matter as long as it is grounded and has current goin to it that is backed by a fuse but id not like to be changing out fuses every couple of miles. any help thanks

 

so when you plug into the stock one it pops the fuse in the truck circuit? or in the part you are plugging into it? sounds like its shorting out inside. it should have a ground from one side and go to constant negative through a fuse otherwise. and ive found the socket splitters useful since i run alot of things at once.
