I rewired a friend's '98 T&C van for brights and fogs at the same time,there was a relay. I just had to pull the ground wire to the relay coil that came from the head light switch and replace it with a chassis ground. Models may vary so don't trust my word on your newer rig. I'm 99. 9% sure that there is a relay on all models though. The relay was under the dash on the T&C almost in the middle drivers side.
