I assume you are talking about the black placeholders right next to the headlights?
Im sure the JDM ones would fit in there, make sure they are genuine and not some ebay knockoffs. To wire them in you can do it from either a switch or you can wire it in with your headlights (personally Id wire it in for when my low beams or parking lights were on). All you need is a ground and a power source, its your preference.
