I have this little black box hooked into my headlight wires. It is an obvious aftermarket, or add on. It simple is a 2 wire little black something with no name on it, the two wires go from this llittle box to the ground and I think high beam power wire at the headlight. It has scotch lock style fasteners so I know it is not factory.
Just cannot imagine how something that has nothing but 2 wires coming out of it "tagged onto" the headlight wires does anything, but I know its not put there for looks LOL
Again the headlight wires are NOT cut and this thing put in as something the power is running through, it is simply tagged into the wires by use of scotchlocks which I do not like.
