You mean a "schematic"? If you want to get real information, become a member of the Spyderclub at www.Spyderclub.com. If they don't know the answer there, I doubt that no one does. There are members from the U.S., Canada, Australia, Mexico, Central and South America, and Europe.
As for your question, I don't know if schematics are available or not, but the members of Spyderclub can lead you by the hand so as to help you solve the problem yourself. If I remember correctly, the Chamonix was constructed by Beck (I may be wrong). Check with Carey Hines at Beck; they might have the wiring diagram for your car.
