today i was trying to put in LED lights they worked in the begining but when i tucked the wires to close stuff up i heard arching and then the light didnt work! do i need to replace a fuse or what? thanks

 

probably a fuse. If your next question is which one I will be happy to tell you that only god and you will know which one as it will depend on which circiut you tapped for power. When I suspect a blown fuse I do not even look in the manual to try and figure out which one. It takes longer to get the manual, try and figure out which circuit you tapped and which fuse it goes to, where that fuse is located in teh fuse box then it does to simply start pulling the fuses one by one and checking them. IF they are all good under the dash then check the one out by the battery under the hood.
