Here is how they do the wiring.

Page 99 of this book expands on the wiring and plumbing. It basically just goes on the inside of the earthbag wall. They tie it into the bags with wire and brackets.

Horizontal plumbing goes in the floor, in the crevices between the bags or through a framed wall that intersects the earth bags. Vertical plumbing goes through the bags or stays exposed on the outside of the wall for easy access. The other option is to hide it under cabinets and behind benches built into the adobe wall.

Essentially, to connect plumbing, you'd come up through the floor like a normal household. If you'd like the plumbing to run flush with the wall, you create a strip anchor that attaches to the bags (the strip anchor is composed of a 10"x10" plywood sheet that has a 10"x2"x4" piece of wood. This 2x4 allows your to nail/secure utilies to the wall.

Strip anchors are also used to secure electrical conduits.
