Corolla 2001

can anyone tell me if corolla 2001 with DRL got negative switched or positive switched?

What are trying to hook up. The DRLs use PWM - ie, they "pulse" power to the lamps, so they will appear to be running at lower intensity and use less power. But that design will also wreck HIDs and some LEDs mods - that's why they recommend disabling or bypassing the DRL system. As for the lamps themselves, they are constant ground (positive-switched).
