I performed this fix quite awhile ago but recall that it wasn't terribly difficult. You do have to remove the steering wheel though. Then you will be able to see the little cam on the left side of the housing, there is a flathead screw in the center. Remove that and the plastic cam should come out. I seem to recall I had to pull the dickens out of it and that it was somehow in there pretty good. When you remove the old one make note of how to connect the wires because I can't remember where they went but I think there were only two. Anyway if you look at the pics you can see it there with the red and white wires. Above that is a lightbulb for the gear display and to the left is the horn contact wheel, you'll notice a copper wheel on the back of the steering wheel that comes into contact with that to operate the horn while in any wheel position. I found that pretty neat. And if you are tinkering around in there with a screw driver there is a very good chance you'll be sounding the horn if your battery is connected. My neighbors loved that part! So go to it! Get a steering wheel puller if you haven't got one otherwise that wheel isn't coming off
