So yesterday when i came come I decided to check around the air filter, it's got a cold air intake and no wheel wells (previous owner lowered and took them out) so I occasionally check on it. Upon looking I found a black and a purple wire with not pigtail or connection on, guessing my tire shreaded it off. I was wondering what those wires went to, the are in the same run that the fog lights wires are in. Any ideas? Thanks
