Yes mtyler11, I made it myself. Each button acts as both a switch and an indicator. The two lighting controls are obvious. " Solar Vent " activates the vent system modifications I posted on earlier. When active and the ignition is turned off, it will run the vent fan from the battery for 5 minutes to dry the evaporator and then switch to the solar panel to keep the cab cool. As I've stated before, I have chronic lung disease so mold in the vent system would render the truck useless to me. I'd have to sell it and get another one. " Recirculate " takes back manual control of the trucks vent system recirculate function. The system will include a two step brightness for the LED's. They'll dim when the headlights are on.different... is it just an indicator or active control knobs? fab it up yourself?
