Ok, been there done that. My wife pulled the lever out and handed me the cable. Funny at the time, not cool though.
Now to replace, You dont have to remove any bolts or anything as mentioned previously.
1: You cant buy just a new cable, you will have to go to a scrap yard and get the whole handle assembly (which is the cable, handle and cover). Dont worry its not expensive nor hard to remove. The assembly is not SHO specific, any same year taurus will do.
With a screw driver, Carefully pry out the headlight dimmer control cover. Look inside and you will see a little metal u-clip on the bottom that holds the ebrake pull lever assembly in place. Pop that clip out. The whole handle assembly will come out now as your cable is broken.
To get the junkyard assembly out you will do the same thing, only you will have to remove the cable from the little metal release lever. You can do this by moving the release lever back (like you are doing now with your foot) and slide the cable forward. The entire clip comes out and the assembly pops out just like your busted one did.
Enjoy.
