How hard is this to do?

I fixed this same problem on mine yesterday, very easy to do...no special tools required ( although a friend and beer helped alot ). Just take the center console out ( two srews on each side below the armrest ) and the top piece is held on with two phillips screws. Pull the old cable out if their are any pieces still in there and have the friend feed the new cable through the floor ( bottom to top) . Loop it around the e-brake spring thingy ( you will know how it goes when you see it, really simple ) then to put the two rear cables on it, just crawl underneath and pull the forward cable to the rear while you slide the two rear cables onto it. Then just put the console back it. The final step is sitting back and drinking a beer and another beer and another beer....
