If you have the stock plastic grommet holding the TV cable to the TB (its white or yellowed form heat and grime) do Like Casey said, use a flat head and gently pry it down,it will pop out pretty easy. If you have the upgraded brass one, the TV cable will be held in by a cotter pin which you have to pull out 1st. The TV cable is pretty durable, I wouldnt worry about breaking that. The stock grommet should be replaced. Preferably by the upgraded brass one but at the minimum, with a new stock one. I got one from Ford for $3.00, the brass ones can be ordered from www.50resto.com for $6.00.
