Just an FYI to anyone looking to run wires through the seat. This video shows the approximate construction of the seat at 1hr 17 min.

The general process is as follows.
1. Pop the two connectors on the bottoms of the seats down. Use caution and leave the ignition off as one of them is an airbag wire. You don’t need to disconnect it.
2. Unhook the two elastic straps from the bottom.
3. Use a trip tool to remove the two plastic trim plugs that hold the seat fabric at the bottom corners.
4. Unzip both sides.
5. Release the clips from vertical wires.
