are 68 -74 headlight wiring the same because i found halos but they said for 71-78 i have a 68 nova will they burn my wires?
and in the add it says it will not hurt or burn wires for 71-78 i was just wondering if the wiring system in the headlights are the same for 68 and 71 like if they produce the same power or what ver so i dont have to do anything else but pop the bulbs in

Welcome to the site. If the lamps draw more than the stock sealed beams it would be best to use relays to power them. It is a simple circuit to build and will deliver full battery voltage to the lamps making them work to the full potential.
