i use the factory linkage for all of them Mode,temp and inside/outside air selectors. had to make a custom connector rod for each motor to do what it needed to do . The hardest part was mounting the 3 motors in a some what position and location like the 3S has. Right now i have zip ties holding all 3 motors in place until i make a custom bracket for a perm solution. I'm just happy that i made it worked with all of the sensors. Photo sensor and the inter temp sensor so the Auto function will work properly. Just finish up the custom dash panel this weekend will post the pic later.

The conversion took me about 4 days from start to finish. first day reading about what to pull out from the donor car and what they look like, finding a car at the Pick n pull place that has a car with all of the stuff i needed. One day pulling out all of the stuff from the donor. two days of installing into the car. total cost of this was about $300 in parts
