I am restoring a 1986 champion telstar and would like to know if there is anyone that owns one or has owned one that may know what the red rocker switch that is mounted next to the rear bed area on the outside of the shower area may go to ? I have traced it up to the rear area behind the refrigerator and further to the control level indicator panel. From there it goes to the headliner area with other wires. It lights and sends 12 volts DC when switched on. So far i haven't been able to determine anything that it activates/powers when switched on. Have any Info?
