I have purchased a pair of factory fog lights for my 2003 mitsubishi diamante, i plugged them into the factory harness that was there. What im wandreing beings they dont just come on is, do i need to install a switch to cut them on and off with, or do i simply need to get a relay fuse for my fuse panel. My car didnt come with a owners manual, and i do not knwo where to go to view one online. Thanks for your time, hope you can help.
