I want to order the 6600 up grade kit for my fantastic fan and am wondering if they are all made for 12V?

I am not at the bus, so can't take a voltage check and because there are so many things on my bus that are 24V, I am hesitant to order the 12V kit without knowing for sure if it will be OK.

Any opinions out there? Has anyone installed the kit on an Elegant Lady?
