You are probably right about the resistor being NTC to protect against overheating
of the socket (due to loose contact with plug) or overloading. Notice the fuse in the negative (ground) side of the socket. This is common on modern cars so you can ruin the socket without blowing the supply fuse.
Most likely a thermistor to reduce the inrush of current, e.g. from a capacitive load, incandescent bulb. To reduce increasing current,
the device would need to be PTC (positive temp coefficient) device.
