Like the original Vision, the Vision SLR must use stepper motors. This implies a requirement for centralized circuitry acting as a motor controller.
Getting this working won't be as simple as where to connect power and ground. However, with a little more information, it would probably be relatively easy to build a rudimentary motor controller around something as basic as a 555 timer.
I got one of thoseIf all you want is to switch independent color control, and not to have it stop or jog or do tricks, then there should be a way. FedSig had those dealer demo beacon models and as far as I know they did not run through a regular controller.
