I just replaced this before Christmas.
I hope you have a small body and hands. The bolts are a pain in the ass to take out (Well, one of them anyways)
issed:
You will have to take out a bunch of screws to take off the plastic cover. These are all easily accessible. Then there's 2 bolts holding the resistor board. The one further in the back is really hard to take out due to the way the floor plastic bends in that area. You can't get a straight tool in there.
