Simple question about the headlights. I have a '95 Thunderbird with the normal (boring) headlight switch (knob) and panel dimmer dial next to it. But I've seen some '96/'97 Thunderbirds in the junkyards with an second dial for "Auto Lamp". Is that for having the headlights come one with the key start (like many modern cars)? Is that something that can be swapped onto a '95 Thunderbird or does it require a different light harness and, if so, how much of the harness is different?
