The thermostat sensor wire goes from the controller to the radiator and is inserted between two of the fins. Fan comes with fasteners that go through the radiator fins to secure it. Instructions that came with the controller are very good. Straight forward easy job, no cutting, no drilling no relocating.
In addition to what BC mentions, high-end aftermarket fan controllers may also need wiring for ignition and an over-ride (full-power) switch. Some controllers also have provision for a hook-up to the A/C clutch, so the fan RPM increases when the A/C is on.
