Variable Speed Controller
The variable speed controller is mounted on the fan shroud.
Wiring is zip tied to the shroud to keep them away from the fan blades.

The VSC also has overrides for Off, and High. However the A/C compressor negative signal input can be use for an override Low (assuming the temp doesn't have it on higher). But I don?t have any of the overrides wired up yet.

One of the things I really like about the Flex-A-Lite variable speed control system is that the fans are started gently so as not to create a huge current draw spike. Turning on the headlights creates a larger spike than this system does.
