The TV cable is a cable from the trans that connects into the valve body and to your throttle body. Most cases its used with a carb so linkage is much easier but you can modify your throttle body to have a bracket for the cable to hook onto im sure. This cable controls the shift pressure in your trans and it MUST be hooked up properly. I would recommend doing some indepth research on how to hook it up or get someone who really knows what they are doing. You can destroy a 700r4 in minutes if its not hooked up properly.
