Back in the day, this is how it would be done. From the “ON” lug on the ignition switch or the lead that feeds the cigar lighter, run a hot wire, through a fuse (10A.) to the fog light switch. From there to both fog lights. Use #14 wire. From the second wire on the lights (ground) run a ground wire, also #14, to a good metal ground or body ground point. The lights will now function from the dashboard switch. The tail lights will not operate from this switch unless you do some fancy wiring.
