Can a 78 Volare cruise control setup work in a 74 duster?

If you have any trouble, I drew up some charts on how it works.
Mike - any info about the wiring setup would be greatly appreciated. The turn signal stalk from the 80 Volare that I pulled the system from will not work on my steering column, so I need to find one. Do you have one for sale or know where I could get one? Thanks - BOB
