So I ordered the retro solutions 55w fog lights and after messing with them I couldn't figure it out....this is what the kit is like. The positive wire connects to battery then runs to a fuse the runs to a relay Which has a ground. I can't figure out where to ground it!!! The wire isn't long enough! Then the wires run down to the bumper where you plug in the first ballast. Once again where do I ground the ballasts? What's the best route to run the wires from either the driver or passenger side battery down to the bunper

 

Preferably to a piece of metal with a self drilling screw doenst matter were and if its nong enough make the wire longer
