Check the relay and is it the correct switch? Or is it connected correctly

Toyota uses a different cooling fan control system and when the fan switch is unplugged, the fans would come on. System uses a continously grounded fan switch until it is broken when temperaturerange is breached.

How long did you run the engine? Is it overheating when the fans do not come on?
