cable in wall with Styrofoam and 1x3s
I need to run nm cable down this wall.
Can I just cut notches through the 1x3s?
They're not supporting anything.
Wood planks go on top as the finishing

I think I would try to go behind the wood in the foam and still use a nail plate.

I would just try to push the wire under/behind the furring. You may have to use a piece of stiff wire to create a channel. Definitely plates..... carefully installed.

Definitely don't cut the boards. Try your best to tunnel under the foam board or gyprock at the point of the cross 1x3's and run it under there. You can supplement what little insulation you have by spraying foam over the holes where the wires go.

Cut the boards! If they are over studs, you have a 3 1/2" cavity behind the insulation board. Unless they are nailed every 8" to concrete, you will have a weak spot. Since you are determined to do it, use mending plates to span across the gap instead of no-nail plates. You need to preserve the integrity of the boards.
