Mike, it looks like the wire is laying on the deck of the car. Can you remove the black box the wire runs through? I would get some small very thin washers and shim up the lever on the cam just enough that the wire clears the cars deck. You may have to do the other end also. Check the bends in the end of the wire, They may not be a square enough and allow the wire to rub the deck. Then look to see if you'll have to clearance the black box for the wire.
Just a suggestion.
