I'm replacing the headunit and this wire called "lights on signal" from the dash radio wire harness to be connected to one of the terminals on the new radio wire harness. There is no corresponding "lights on signal" terminal on the new radio wire harness. What does the "lights on signal" do and where should it be connected? Could it be connected to the "+12V ignition" wire to the radio?
Many aftermarket headunits don't require the signal to adjust the panel light brightness. Factory radios use this when the headlights are switched on, therefore it is a "[head]lights on signal". Just cover it with insulating tape; don't connect it to anything. If you do, you will likely blow fuses or cause other problems.
Bingo, thanks Walt!

It's not only a (digital) on/off signal, but a signal to dim the radio display with the dashboard lights.
