Went to the junk yard and scored a headlight switch with the fog light button so I grabbed the bumper brackets and the harness from the plug under the bumper to the light as well. After a few minor modifications to my bumper cover, I now have some KC Daylighters mounted up front but they wont turn on. The "Auto" setting on the headlight switch works so what am I missing? Relay? Fuse? Both? Black wire on the original harness; "hot" or ground?

This has all been covered but I'm feeling generous. How many watts are them there "KC" lights? The factory fog light wiring is only rated for 35 watts or so, plus they only come on with the low beams. Also make sure your wiring is correct.
