Furring Strips Up and a start at electrical

I got the furring strips up over the past week.  All looked good until I put a level up vertically on the wall.  I couldn't figure out why, until I realized I had sealed behind the rigid foam insulation with expanding spray foam.  The spray foam pushed out the top of the wall, so I had to do a little foam shaving to keep the top furring strip in line with the rest of the wall.

The electrical boxes are now all nailed in, and 4 of the 10 recessed light cans are installed.
