Thanks for the reply william1978.
The panels are self supporting. They attach to the floor and the ceiling framing using a bracket system and screws. There are no studs or framing, just 4' wide by 8' high panels that are 3 1/2" thick. The panels install next to each other in a line to form a wall. The wires are pulled with string, fished, or pushed through either the 1 1/4" channel that goes horizontally through the foam insulation, or are fit into a channel cut into the back of the foam as described in my initial posting.
Occassionally, electrical inspectors have some reservations about this system because it is new, and they cannot see the wires run through channels or the chases in the foam for the rough inspection, as they can in typical stud framing.
Of course they can see the wire at the electrical and junction boxes on the rough inspection, but some inspectors want to view this as "new work" and they ask about supporting and securing the wire because they view this as a new wall assembly, and others see this as "old work" as if we are fishing in a wall assembly that is already finished.
I'd like to have some exact code references that I have confidence in as ammunition if we are going to challenge the electrical inspector in the field on the issue.
Thanks for giving this some thought!
