you only need the cable, but get it all apart so you know which cable you need.
take out the bolts that hold the handle. then push in the little "keepers" that hold the ebrake handle when you pull it out, you have to push it in about 1/4" farther back then where it would be if you just release the ebrake. once you do that you can remove the cable from the back.
its sound confusing but is easy. let me know if you need a pic.
