I bought these new awesome headlights for my M-2112 Freightliner and they are basically plug-in, with the exception of the red wire to "ignition on 12 volts" for the LED light bar. So, exactly where would be a good electrical connection point (possibly somewhere on the firewall) for the red wires to pick-up the M-2's ignition-on 12 volts?
