In the block on the right front fender. Just unplugs and a new one plugs in. Check both of the fuses first though. The pumps get moisture in them that rusts the bearings and makes them run hard and fail. They tend to take out the AIR fuse (30 amp) in the same box when that happens. The pump is easy to change as well if you find it is drawing excessive current.
