The yellow line basically comes through the firewall, hits the drivers footwell, goes across to the passenger side then down the right side of the car to the fuel door then trunk. I'm guessing on the sedan it must cross over to the back left door somewhere.

When finding door lock issues, always start with the fuel door. Bypass the actuator completely, if that doesn't fix it, head for the drivers door. The problem is usually in one of those places.
