You can just tie the (OEI) Output Enable Input to ground. (No resistor required)

If you want more control later, you can connect OEI to a PIC pin. Then HIGH is LED"s OFF, and LOW is LED's ON.

But, you can still turn them ON/OFF by putting 0 or 1023 in the PWM register, so using OEI doesn't help all that much. Which is why I say, Just ground it.
