So is there a way to create a switch and battery pack so i dont have to use my car has the controller of the trailer?I was thinking like jury rigging a switch that would toggle the turn signals.and another switch to turn both on at night.and one of corse to toggle a stop.Maybe the stop on i can rigg under the brake peddal.<br /><br />by the way the van i speak of is a pontiac trans sport from 1992.
