I lied. I was thinking of a different set I had. On my current set, I ran the wire through the screw hole in side the door and through the fender.
Then I grounded them at the fender. That's my red wire used for a ground, it's the only wire I had available.
Then I ran a thin peice of telephone wire to the turn signal where the bulb plugs in. I don't have a pic of that. Just unplug the connection and put the end of a stripped wire in and plug it back together.
