I'm in the middle of changing rear bumpers on my 90 /forums/images/graemlins/k5.gif and noticed a wad of wires tied up between the tank and the bumper. There's a two piece one that's red and blue and a couple of black ones. One has a split coming out for my license plate light. There's a hitch on it but no trailer light hook-ups. These are 3-4 feet long and tied up like the factory did it with some, dissconnect before tying, warning tags on them. Any ideas?
