cole hersee makes the switch
www.colehersee.com. The one i have is out of a blue bird school bus. The only place that i can find that carries cole hersee switches are heavy truck and bus places. If you get a switch for something other than a blue bird the wiring may be different cole hersee has a bunch of switches that look identical but they are different. And yes i was thinking of putting together a kit of sorts but i have to see if i can get a little bit of a break on the switch prices. I will post when i know more about that.
