Anybody run the Rosta of DD cruise on their swap?

[Joyridin]

I bought the Rosta Cruise Control kit, but cannot seem to get it to work. I checked the part numbers and they seem to be different between the 2 kits, although many said they were the same.

I am getting the voltage in/out, but it won't engage. The LED in the back is not lit either. Whether that is for the DD version only, I am not sure.
