how do i go about doing that. my fogs give some decent light output now that they are faded. i came up on a whole bumper usdm fog lights with harness a,b, and c and switch. so what do i have to do so they turn on without my headlights being on

 

u install the switch into the center console. there should be a un-used port opposite the hazard light switch next to the clock (this is for 94-97 accord but 90 should be similar) there u can install the fog light switch. this switch will let u turn the fog lights on without needing the headlights. there are foglights on ebay which use this OEM/EDM switch placement and thats how i know
